Greetings!

I always try to keep in touch and answer questions from my own readers.

One of you was interested in how to correctly install sills on plastic windows.

The installation of the window was done by his amateur friend, but he did not bother about the external drainage of water from the window.

You can read what ebb tides are and at what angle to install them in this post.

I especially recommend reading to all those who practice self-installation of window structures.

Shimmers for wooden windows - types and installation

The ebbs in the window structure perform an important function - they protect the area where the frame and window opening meet from the destructive effects of precipitation.
Drains, in accordance with the installation rules determined by GOST, are installed together with any type of window - plastic, aluminum, or wood. It is worth noting that when talking about low tides, the term “external window sill” is rightly used to designate them. In order for the service life of the light-transmitting structure to be maximum and not dependent on external factors, it is necessary that the material from which the installed drainage system is made is resistant to the negative effects of weather conditions on it. Also an important circumstance affecting the service life of the window is the competent execution of work related to the installation of the ebb.

Let's take a closer look at the types and features of installing external window sills in relation to wooden windows.

From the article you will learn:

General requirements for geometric parameters of ebb tides

Before choosing a particular product, determine what size it will be and what basic requirements will be placed on it:

• Based on the width of the window opening, the length of the future product is determined, plus 2-3 cm are added on each side. When determining the width, it is necessary to take into account the angle of inclination.
• Unlike what material the building is constructed from will determine the configuration of the metal product. Thus, a design made for a wooden house differs from a product intended for a brick building.

Configuration

• The selection of colors depends on the color design of the window frames. It is advisable that they do not differ, because this will disrupt the decorative component of the overall finish.

Existing types of sills for wooden windows.

Modern wooden structures, although they are coated with compounds designed to prevent the development of rotting processes, nevertheless, with prolonged exposure to moisture, the applied protective layers may be powerless against it. Therefore, special, increased requirements are imposed for the ebb of a wooden window.

Today, drainage systems made from the following materials are most often used to organize effective drainage of water entering the window structure:

Installation instructions for drip tides

Tides are designed to provide protection from adverse weather conditions. Low tides allow water and snow to flow down to the ground and not accumulate on the window ledge or foundation. Flashings significantly extend the service life of facades. The main material for their production is aluminum and galvanized sheets.

Low tides are divided into

•Window sills

•Ebbings for the foundation

•Shields for fences

Specifics of installing ebb sills on wooden windows.

Before installing the drainage system, the following circumstances must be taken into account:

It should be noted that the Russian market for window products can also offer the end buyer soffits made of wood. It should be taken into account that such products are very sensitive to weather changes, and are also quite demanding in terms of care: protecting the surface from damage, periodically wiping it from dust, and frequent varnishing are indispensable companions for drainage systems, the basis of which is natural material.

How to install drip sills for a plinth with your own hands

Due to the active development of individual construction, thousands of houses made of wood and brick are built and repaired every year. In this case, special attention is paid to the construction of the foundation and plinth, which are the basis of the entire structure.

They must securely hold the building on the ground and prevent moisture from entering its walls.

Window sills and sills for wooden windows. Material selection

New wooden windows transform a house or apartment and give it not only an aesthetically attractive appearance, but also comfort, protecting it from dust, noise, and weather conditions. The atmosphere in the room largely depends on how well the window units are manufactured and installed. But, speaking about the windows themselves, we should not forget about such components as window sills and ebbs. The first ones are installed in the interior of the room. In addition to their decorative function (usually this is a place for placing indoor flowers), window sills also serve as a structure on which they rest when washing windows or hanging curtains. Therefore, the strength characteristics of window sill planes are no less important than their appearance.

The most affordable ones are plastic window sills. Despite the fact that the material for their manufacture is the same, the quality of finished products from different manufacturers can vary significantly. As a rule, cheap models from Russian manufacturers, so widespread on the market, do not serve their owners for long. After just a couple of years, window sills lose their attractive appearance, become covered with cracks, scratches, sometimes break in the corners, and are pressed through, especially with a large surface area. More expensive imported analogues withstand everyday tests much better. For example, the German company produces quite competitive products that are capable of successfully performing their functions; rather, they are decorative: plastic is plastic.

Window fixing

And yet, wood, wood and once again wood occupies a leading position in the window sill market and is installed under the windows in most residential buildings.

However, not all wooden window sills have the same properties and characteristics. The strength, hardness, and durability of the structure depend on the type of wood. Traditionally, hard woods are used to make window sills: oak, beech, Siberian larch. A cheaper option is pine, but the softness of this wood becomes obvious in the literal sense: traces from heavy flower pots and hard objects remain in the form of dents, spoiling the appearance of not only the window sill, but also the overall impression of the entire window.

When choosing a size, remember that during installation the window sill must lie on the window sill space at least 2/3 of its width. It is recommended to set the “removal” of the window sill into the space of no more than 5 cm. This is also important to ensure normal heat exchange in the window opening, where warm air from the radiators washes the inner glass of the double-glazed window. Installation of very wide window sills requires the use of additional supporting structures.

As with window sills, the width of the sills can vary. Manufacturing companies offer products from 90 to 360 mm. To give the ebbs a more attractive appearance, special side linings are produced, usually made of ABS plastic.

What materials are they made from?

The materials used to make external window sills are varied, but each of them has its own disadvantages and advantages. Next, let's look at the features of each material separately:

• Sheet steel products. Despite the fact that products made from this material are still in great demand due to their low cost, manufacturers have begun to produce them less frequently. This is due to the fact that the material is subject to corrosion. In order to prevent this process, it is necessary to additionally carry out powder paint treatment. Despite this significant disadvantage, there are also advantages:
  the material has increased strength;
• It is possible to cut a part of any size;
• has different colors;
• do not respond to temperature changes;
• easy to care for;
• resistant to sunlight.
• Drain made of aluminum. Structures made from this material will last longer than metal products. This is due to the fact that aluminum is not subject to destruction by corrosion. The width of the products can reach up to 35 cm. Designs are available for sale in only two colors - brown and white.

Aluminum drainage

If you want to change the color, you can always resort to powder paint of a different color. The only drawback:

1. Aluminum flashings are more expensive and require additional sound insulation, as they produce increased noise during rain.

• Plastic drainage. In terms of practicality, PVC products occupy a leading position. The material is practically free of flaws. Among the advantages the following can be noted:

1. the material is moisture resistant;
2. easy to install;
3. not demanding in care;
4. has excellent sound insulation;
5. aesthetic appearance.

Despite all the advantages, this material has one significant drawback - it is fragility. If any heavy objects hit, the drainage pipe immediately splits. When the temperature drops, this quality only gets worse. Therefore, in conditions with low temperatures, installation is not recommended.

Plastic

• Made from epoxy resin. The material is extremely durable because it contains fiberglass. External window sill made of epoxy resin, can be brown, black or white.
• Water drains made of polyester. An additional polyester cover is used on the galvanized window sill. Such a detail functions not only as protection, but also as a decorative layer. Manufactured from polyester, polyurethane and pastisol.
• Galvanized drains. The most common colors are white and brown.

Important! A significant drawback is increased noise during bad weather.

Galvanized castings are manufactured from alloy steel. They have an additional polymer coating that protects drainage from the effects of acid rain. In addition, the price of the product is quite affordable.

Types of tides for windows

Any windows from the outside are equipped with a flashing - this is a special board mounted at the bottom of the window opening. It needs to allow rain or melt water to flow down it. This is probably why this part is sometimes called drainage.

Installing window sills is the final stage of proper installation

Window sills can be:

If you install the window sill correctly, the wall will not be damp

Currently, external concrete castings are almost never done. Or rather, they are made, but they are still covered with either plastic or metal. Concrete slopes can, of course, be whitewashed, and this was once done. But today this type of window decoration is very rare.

If we talk about the exotic, we can recall stone tides. They are made from polished granite or marble. They certainly look great, they don’t make any noise, and you can only break them with a sledgehammer. But their cost is not for every wallet.

Stone tides - look gorgeous

There is another interesting type of external window sills - from facade tiles. It works great with any window - both wooden and plastic. If your basement or the whole house is decorated with similar tiles, it will look very “on theme” on the windows. At the same time, the house looks like a single ensemble. Such slopes are made extremely simply: the tiles are cut so that they protrude 1 cm beyond the walls, and the desired slope is formed using a cement-sand mortar. The seams can be sealed with cement laitance, or a hydrophobic impregnation can be used. It’s just better to install such slopes before finishing the exterior walls.

Flashings from facade tiles - easy to do with your own hands

Although window slopes come in different materials, the vast majority of homeowners settle on two: plastic or metal. Each of them has its own pros and cons, and we’ll talk about them in more detail, as well as how to install window sills.

Step-by-step installation instructions

Correct installation of the structure will not cause any particular difficulties. Start work by cleaning the window opening into which the ebb and slopes will be installed. To do this, remove all irregularities, cut off excess construction foam and rid the surface of dust and dirt. After that, carefully read the installation nuances and take into account the opinions of professionals.

Important! If, after filling with foam, voids are found in the inter-window openings, be sure to fill them by foaming again. Only after complete drying and trimming of excess polyurethane foam will it be possible to begin installing the metal window sill.

Let's consider the sequential installation of ebb tides:

1. Before installing the window sill, it is necessary to fill a platform of cement-sand mortar under the structure itself. After the surface has dried a little, remove any unevenness with a spatula.
2. Under the slopes, we cut a groove with a grinder with a diamond blade. The side parts of the ebb will be inserted there.
3. We take measurements for the future design.
4. We transfer the dimensions to the metal product and cut off the excess.
5. We apply “liquid nails” to the prepared window sill.
6. We insert a metal window sill into the cut grooves.
7. All seams and joints must be treated with silicone sealant (colorless).
8. After the window sill is completely installed, the window is transformed.

Plastic: good or bad?

Plastic window tints are considered the most “quiet”. When raindrops fall on them, there is almost no sound. And they are also considered inexpensive, which is important if the budget is limited. Only unpainted galvanization is cheaper, but its appearance, after several years of use, is not very attractive, the paint holds very poorly.

What are the disadvantages of plastic moldings? The fact is that plastic loses its elasticity under the influence of ultraviolet radiation, becomes brittle, and can crack under load. And, even if there are no serious cracks, there are always microcracks. They form over time and become filled with dust. After a couple of years, the once snow-white plastic becomes grayish or has a yellow tint. Nothing can wash it off. If installing window sills every five to ten years doesn’t bother you, you can use them too.

Plastic ebbs are two planes connected by jumpers. You have to step very carefully

The following disadvantages of plastic moldings are flammability and significant thermal expansion. Plastic melts at high temperatures. If a cigarette butt gets on it, a hole will be provided. It may not happen that often, but there is a possibility.

Thermal expansion manifests itself if the installation of window sills on windows is done rigidly - the strip is fixed with self-tapping screws. Then, in hot weather, it “goes in waves” and bends. Afterwards, it usually returns to normal. In order not to worry about thermal expansion, oblong rather than round holes should first be made in the edge of the ebb, to which it will be attached. When tightening the screws, do not press down the plastic too much. Then, when changing the size, the plastic casting will not “behave”.

Plastic drip installation

The second point is to leave a thermal gap on the sides, which is filled with silicone waterproof sealant (for outdoor use). In this case, thermal expansion will not cause a “wave”. The plastic will simply expand a little, compressing the sealant, then return to normal. So installing plastic drip sills has its own nuances.

Or you can do it somehow without them - they make too much noise

In the summer rain, you want to open the windows wide and breathe, breathe... Leave the shutters open all night... But the drops drum so hard on the ebb tide that you won’t be able to fall asleep sweetly. The question arises: have there been any other tides since our childhood? Sometimes it seems that with wooden windows it was not as noisy as with new ("quiet") plastic ones.

Explains a physicist, a specialist in ventilation and window systems.

Are tides needed on any windows?

No, only on quarter-length windows. What is meant? The fact is that the main walls of the house are thicker than the glazing thread (which is logical: after all, the house is not a bus). Therefore, when installing, the window block is moved towards the room.

“Quarters” are made from left to right to top. Below is the end of the wall. It will collect water when it rains. To prevent this from happening, an ebb sill is installed on the street side - an external window sill with a slope sufficient for water outflow. It is worth noting that in apartment buildings in Russia the majority of windows are of this design (options are possible abroad and in private houses).

What is there to argue about - low tide costs a penny! Take it and do it

The problem is not the price, of course. The problem is that if you install a low tide, the new windows begin to rattle. The poorly secured ebb tide rattles with every gust of wind. But if it’s (seemingly) well made, it bothers me during rainstorms: raindrops sound like a dull drumbeat. Why is this happening?

The point is in the design features of ebb tides from the “mass market”. What window companies usually offer at the time of window installation are flashings made from thin-walled materials. Most often we are talking about profiled plates: aluminum, galvanized steel, copper or plastic. At one end they are closely adjacent to the window profile, and at the other... they hang in the air. And this is the main problem.

From a physics point of view, we have elastic, thin-walled, lightweight membranes that produce sound when struck. Why be surprised - they should sound: a xylophone, timpani or a jew's harp work on the same principle of vibration of a metal plate.

Okay, but we have a “quiet window”... Shouldn’t double-glazed windows dampen this whole
“ orchestra ” ?
Firstly, as soon as you have opened the window, it is pointless to talk about its sound insulation parameters. Secondly, the sound of rain is transmitted not only through the air, but also through the structure of the window itself. The point is in the method of installing the thin-sheet plate: one end of such ebbs is adjacent to the window profile. Vibration (sound) is transmitted through this junction point into the room - that is, the window profile itself sounds. This means that the drumming rain will be perfectly audible in the apartment even with tightly closed “soundproof” double-glazed windows.

Average prices for creating a product by region

Depending on the region and the material used to create the tide, prices for products can vary significantly; average prices in various major cities are presented in the table:

City	Stone	Metal	Galvanization	Plastic	Concrete	Clinker brick	Tree
	Price rubles per m
Moscow	400	130	140	85	300	250	280
Saint Petersburg	410	135	120	90	310	265	250
Kaliningrad	420	130	140	82	310	240	260
Novosibirsk	395	140	150	89	305	245	270
Vladivostok	500	160	170	95	330	280	300

Step-by-step installation technology

The installation of the drip tide is carried out after the installation of metal-plastic windows, when they have already stood for several days, the mounting solutions and foam have already dried. All excess mixtures are carefully removed with a sharp screwdriver or a blade with a chisel. The dried polyurethane foam is cut off with a sharp knife so that there are no protruding nuances.

1. According to standards, the ebb should penetrate the side walls by at least 2 centimeters. To do this, use a thin screwdriver or drill to carefully knock out even holes at the level of the future surface.
2. Even if the product was made strictly according to the given technical parameters, a situation may arise that somewhere it still does not fit into the grooves. To do this, it is necessary to eliminate all interfering errors using a tool. It is advisable to start from the wall - carefully remove all construction debris from the work surface, knock down all protrusions, sweep away dust with a broom or brush. The window sill can be trimmed or wiped with a hacksaw or sandpaper, respectively. The main thing is not to scratch the surface, but to paint over all exposed metal with enamel of the appropriate shade.
3. Once both the surface and the ebb are ready, you can proceed directly to installation. The wall on which the ebb will be attached needs to be slightly moistened with water. Polyurethane foam sticks much more easily to a damp surface - and it will be the main fixing agent. The window sill is carefully inserted into the prepared grooves - there will be punched strips on the sides, and on the side of the window there will be a niche specially created for low tide. The gaps should be minimal, the window sill should not move in them, but there is no need to grind in, because this will damage the enamel surface.

1. The angle of inclination is set - it should be directed away from the wall so that the moisture drains directly to the ground. The horizontal slope is measured using a building level. The tilt in all directions is adjusted by plastic plates that move along the working surface depending on the desired result. The slope should be such that the exposed window sill can be pressed down with bricks wrapped in a rag. This will allow it to be securely fixed when the polyurethane foam expands.
2. After the ebb is exposed and secured, the cavity under it is carefully filled with mounting foam - this will glue the slope and ensure the insulation of the window opening from moisture and drafts.
3. After the tide has stood for several days, the bricks are removed, and all the seams around are rubbed and puttied. After completion of all work, the ebb is completely ready for use.

Metal - types and features

Metal window tintings are durable and there are no problems with them during operation. Installing metal window sills usually does not cause problems. Their disadvantage is “noisiness”. Raindrops can “knock” quite loud sounds out of metal. The problem is partially solved during installation - all cavities must be carefully filled with polyurethane foam. Any emptiness will act like a drum. So here we try to do everything as best as possible.

Metal window sills will be even quieter if foam rubber or any other sheet sound-absorbing material (for example, linotherm) is glued underneath. But it must withstand significant temperature changes - outdoor operation. These two techniques together will make the metal cast not too noisy.

When installing, do not leave voids and use vibration-damping, frost-resistant materials

As already mentioned, metal castings can be made of galvanized steel coated with polyester or plastisol. Galvanization with polyester - metal tiles are made from this material, so the technology has been proven. Such flashings are not too expensive, and you need to look for them in companies that produce or sell metal tiles or similar roofing materials.

Plastisol coating is a more expensive option, but it is thicker, making the metal less boomy. It is also interesting because the surface can be not only smooth, but also “leather-like”, embossed, etc. If your budget allows, try galvanized metal casting with plastisol coating. There are no negative reviews yet.

Another option for a “quiet” metal window sill is powder-coated aluminum. This metal itself is not so “ringing”, due to which the noise level is reduced. Everyone knows the advantages of operation, as well as the fact that the cost is not low. Installing window sills on aluminum windows is a good idea, but it is not so easy to find. Aluminum casting is not particularly popular, so you will most likely have to order it online. Especially if you live in a small city.

A bit of materials science

In addition to the drain board, metal and plastic flashings are used in wooden houses.

Metal products for water drainage are steel, aluminum and copper. Of the steel ones, the most in demand are galvanized castings and those coated with a polymer film. Their performance characteristics are higher, and they also have different colors.

Plastic products are good for everyone and there are even special elements for corner joints. They are inferior to metal ones in terms of strength, but win in price.

What are they, are they needed?

The ebb for the foundation plinth is a strip that resembles a shelf . The ebb is installed along the entire perimeter of the protruding part of the base with a 5-10 degree slope in the direction opposite to the wall. Installing such a strip allows liquid to drain from the surface of the foundation.

The ebb for the base is made from waterproof materials, either independently or to order in specialized stores.

Installing this structural solution allows you to extend the service life of the foundation and avoid its destruction under the influence of moisture and low temperatures.

Neglecting to install the drip lining for the base leads to rapid destruction of the base and a decrease in the load-bearing characteristics of the foundation. Subsequently, this becomes the reason for the formation of cracks on the surface of the walls of the house, requiring urgent reconstruction of the entire monolith. A particularly neglected foundation can lead to the destruction of an entire building.

Preparatory work

Usually, drip tides are installed together with new metal-plastic windows, then the installation is carried out by the same team, and this is already included in the cost of the contract. But the need for installation may be due to several factors, such as replacing an old, damaged sill, installing a metal window sill on a previously installed window (it can be either wooden or metal).

In any case, to independently install an external drip sill, the first thing you need to do is make or buy one. To purchase, you can contact specialized stores if your sizes are typical.

If you are unable to take measurements yourself or require a product of complex shape, then it is best to contact specialists who will competently take the necessary measurements and take into account all the nuances at the installation site.

Immediately before installation you will need:

ready-made and available low tide; hammer drill or impact drill; hammer and chisel, sharp construction knife; broom or soft brush; sandpaper and a hacksaw for metal; building level, plastic pads.

Deciding on the sizes

Metal castings can be sold in long strips - up to 6 meters long; you can find companies that will cut them into pieces of the length you need. The second option is good, since you don’t have to think about where to put the leftovers. The length of the window sill is determined by the width of the opening. The ebb board is usually made wider by 2-4 cm on each side. When preparing, the excess is cut off, leaving protrusions on both sides of the window opening. But you can cut it exactly to the width of the opening. It depends on the exterior wall finish and your desire/taste. In any case, if you order planks of a certain length, and do not cut them yourself, add a few centimeters - this way you can correct it if they are cut crooked.

The dimensions of the window tide are determined by the window opening

The depth of the tide on the window should be such that its edge protrudes a few centimeters. You don't need a protrusion that is too large - it can get in the way, but 4-5 cm is quite normal. In this case, the flowing water will not fall on the wall or under the foundation. With such a protrusion, moisture pours onto the blind area around the house, then goes into the storm drain.

Metal window sills have a larger range of sizes

When choosing a plastic casting, you may encounter difficulties. The narrowest ebb is 15 cm, and then the increase occurs in a certain step. Typically this step is 50 mm. So there may well be a situation - either too little or too much. You need to make a decision based on the situation - how critical is the ingress of water close to the foundation, how often do people walk along the windows. After evaluating these factors, you can choose a wider or narrower one.

Selection by size

The protrusion of the foundation relative to the wall can have different sizes, so most of the ebbs from all the listed materials are produced in several standard sizes according to the width of the shelf. For example, metal products are made from 5 to 40 cm wide in increments of 5 cm, and their standard length is 2 meters.

Each manufacturer sets the dimensions of heavy concrete slabs themselves, but most often on sale there are plinth sides with a length of 39 and 61 cm.

When selecting the ebb according to the width of the shelf, you should add an overhang of 2-5 cm to the width of the ledge, which is necessary to remove atmospheric moisture from the wall, as well as a slight slope for better drainage.

Installation of ebb and flow on PVC profile windows

Regardless of the material - metal or plastic - the window sill is installed according to the same scheme. In the case of metal, gaskets are needed to reduce noise, but the general procedure remains the same.

There is a special protrusion in the frame profile for installing the ebb. The upper edge of the ebb goes under it. But this protrusion is only available if the PVC window was mounted on a stand (mounting) profile. Then installing the slope is a very simple matter. It must be cut to the width; if necessary, rubber or other material must be “planted” on the back side of the plank with universal glue for “silence”.

Correct installation of sills on PVC windows

Then all that remains is to insert the projection of the ebb into the groove, blow out the required amount of foam, and fix the ebb to the stand profile with three or more self-tapping screws. To prevent leaks from the sides, the areas where the ebb tide joins the window opening should be coated with silicone sealant. It’s better to take a transparent one - it will be less noticeable.

What if we play it safe?

To be on the safe side, before installing the ebb in the groove, you can apply the same silicone sealant. This will definitely prevent water from getting inside, even with a very strong wind directed at the window. The second “control shot” also concerns waterproofing. It is relevant for materials that are very susceptible to getting wet. For example, this is exactly what it is advisable to do when installing slopes on windows mounted in a frame house. In this case, before installing the window sill, a waterproofing tape is laid. It is advisable that the tape hangs over the wall - then even if some of the water gets on it, it will still end up outside the walls.

For those who like to play it safe

For waterproofing, you can use any rolled material that is suitable for outdoor use and can withstand frost and heat. Installing window sills in this way will prevent the area under the window from getting wet, even if the rain is very heavy.

If a plastic window is installed without a support profile

What to do if a plastic window is installed in violation of the technology and the groove is inaccessible? During installation, a plastic window is often leveled using triangular bars. After alignment, the window is attached to the opening, and the bars are left as is. If this is your case, you can secure the slope to these bars. If necessary, they can be trimmed. You just have to work carefully so as not to move them.

If everything is already installed and sealed, only the frame frame is available, you can screw the ebb to the frame. To seal, you can use a sealing gasket (rubber tape) and coat it with the best possible sealant. Additionally, you can screw some kind of flashing on top. Maybe he can save the situation a little.

Incorrectly attaching the sill to the window frame

But even with this approach, there is no certainty that water will not flow in. Maybe initially everything will be fine, but over time moisture will clearly get in. So, if possible, it is better to dismantle the incorrectly installed plastic window and install it again - according to the rules.

Installation technology

Correct tide position

In general, the technology for installing window sills or ebbs is simple and can be done with your own hands.

To illustrate the technique, let's look at how to install the most popular version of ebbs - from a steel sheet.

In the sequence of actions given below, we tried to take into account all the features of this process, but we must take into account that for each type of material there are separate technical nuances.

First of all, please note that the correct design of the ebb means that there are no open joints between the window sill and other finishing elements.

This rule should be observed when installing drainage of any type, including installing a PVC window sill with your own hands.

So, instructions for installing ebb tides:

1. Assembly should begin with precise marking of the workpieces and determination of attachment points for decorative inserts (if any are used).
2. The next stage is marking and drilling holes for the screws with which the ebb will be attached to the landing strip. To install the window sill correctly, it must be attached to the mounting profile.
3. If the window opening is equipped with slopes, then it is necessary to consider the possibility of assembling the flashing in such a way that the side joints are also protected from direct water ingress.
4. Next, you need to create an elastic cushion between the frame and the ebb. To do this, we recommend using polyurethane foam with a low expansion coefficient.
5. Immediately after laying the foam, you can begin to fix the ebb in the working position, which can be done using self-tapping screws with closed heads.

Features of tides for wooden windows

A groove must also be made in the frame of a wooden window for installation. In this case, there are no problems and installing window sills is no different. To be on the safe side, you can also lay a strip of waterproofing under the tide, tucking it into the same groove. When using a sealant, you need to look for one that has good adhesion (adhesion) to wood and metal or plastic - depends on the type of casting chosen.

External tides on wooden windows

If there is no ebb groove in a wooden window, you can make one yourself. The groove is not made too deep and wide. This may be a narrow cut into which only thin metal can be inserted. To prevent wood destruction, treat the cut with protective agents before installation. As a last resort, you can apply paint.
