Size of a Quarter Window Opening in a Brick Wall

Installation methods in different openings are not fundamentally different. After all, the protrusions only additionally protect the structures from falling out, blowing and exposure to moisture. At the same time, frames in different types of openings are subject to the same loads, so they must be fixed taking them into account. Installation of quarter windows is carried out according to the requirements contained in GOST 30971-2012, which can be found in a special review on OknaTrade.

This method of constructing external walls is also effective in the construction of concrete and wooden houses. In all cases, the resulting side does not completely cover the frame and serves as an additional barrier and support for it. The presence of a protrusion makes it possible to install a quarter window according to GOST.

If the necessary measures are not taken during the installation of windows in openings without a quarter, then depressurization of the installation seam and premature wear of the hardened foam are possible. As a result, the energy efficiency of any windows decreases, condensation occurs, mold and mildew develop, and even there is a risk of structural deformation. To avoid such unpleasant consequences, you need to correctly measure and then install.

Quarter window measurement

However, situations often arise when knowledge of the dimensions of window structures is necessary to obtain a preliminary cost estimate. In this case, a small error is not terrible, and you can measure the window for such purposes yourself.

When performing this procedure, you need to correctly measure the light opening and determine exactly how much overlap the frame profile will have with the protruding section of the wall. After all, a quarter of a window, the dimensions of which ideally should be 65 mm on each side, in practice can be anything. According to the rules, the window frame must go inward beyond the light opening:

The recommended algorithm of actions can be used only in cases where the openings do not have significant distortions. In more complex situations, another technique is used, based on inscribing a rectangle into a trapezoid, parallelogram or irregular quadrilateral. These actions should only be performed by the master.

Although all of the above advantages are of great importance, it is necessary to place special emphasis on a high level of tightness. Thanks to this characteristic, heat loss is significantly reduced, windows fog up less, and mold does not form on frames, sashes and slopes.

If the installation is carried out incorrectly, dampness and mold will quickly appear in the room.

The frame should fit easily into the opening intended for installing a window. Window sills inside and outside are secured with a thin layer of mortar; a niche is provided for cladding.

Pitfalls of buying plastic windows without installation

Even installers from a specialized company can make many mistakes, let alone installing plastic windows on their own.

A modern person does the right thing when he decides to replace old worn-out windows with new plastic ones, since they are convenient, durable and have good thermal insulation. But many people do it completely wrong when they choose the installation of structures as one of the savings, since the degree of functionality of the windows directly depends on it.

Of course, the statement that professional installation does not require costs is false. But once you do everything properly, you can avoid future expenses.

Window installation is a labor-intensive process. And even professional installers make mistakes, let alone installation with their own hands.

Self-installation is a very labor-intensive process, and it is better for a person without experience to turn to specialists. In case of mechanical damage to any part of the window, no claims will be accepted against the manufacturer. There are many pitfalls when a person orders plastic windows without installation or uses the services of a company that did not fulfill the order. Even if the product sold was ideal in all respects, incorrect installation will not protect against frost or drafts.

When the structure has just been installed, it is impossible to determine the quality of the installation seams made, which always look solid and durable. But after time, wind begins to blow through them or water accumulates, leading to the formation of mold. This happens either due to savings on materials and the unprofessionalism of the installer.

All mistakes made during installation inevitably lead to a decrease in service life and ease of use.

One of the common problems is installing windows with glazing beads on the outside, which leads to unimpeded entry of ill-wishers.

It is very difficult for one person to install a purchased product strictly according to the level, which leads to difficult opening or closing.

Often they forget to isolate the polyurethane foam from direct exposure to ultraviolet radiation, which destroys it over time.

Without practical experience, it is difficult to accurately measure the installation height of the window and the window sill, as a result of which the window unit is installed low and the window sill does not fit. Then you have to compare it with the window frame.

Those who do not secure the frames and simply fill the openings with polyurethane foam also act incorrectly. This quickly leads to the formation of cracks on the surface of the slopes, and the structure itself becomes mobile over time. In cases where the window is without a quarter, the entire structure runs the risk of falling out onto the street, examples of which exist. Foam does not act as a fastening element here, and the structure must be resistant to loads even without it.

In addition to poor opening or closing, you should pay attention to the amount of force required for this. A window that does not close tightly and is ventilated also indicates improper installation. In this case, the sash will sag downwards or the window will not hold firmly in the opening. You should never allow the window to “hang” on the dowels, since the plastic structure has a lot of weight, and foam and dowels will not be able to hold it. It is correct to place the window on supporting blocks that cannot be removed at all.

Even installers from a third-party company can leave a gap between the structure and the wall. But there it will be possible to make claims, and if you work independently, you will only have yourself to blame.

It is very important that the product is sold and installed by the same company, since each profile has its own individual characteristics. As an example, we can cite “warm” aluminum windows that are installed exclusively on anchor plates, and not on anchor bolts or self-tapping screws. The latter can very easily damage the polyamide thermal insulation layer located inside the frames. Even if a master knows all the features of fastening window structures, this does not mean that he will not make mistakes. The installer may also fail to check the level of the frame by installing it askew. Third-party companies very rarely admit such a mistake, because they will have to dismantle all the slopes again and correct the position of the window.

Thus, only the company that sold the plastic window can professionally install its product, and in case of violations, claims can always be made against it.

Installation of window blocks in openings without quarters

If there are openings without quarters, the position of the window block along the depth of the opening can be any. True, for architectural reasons, as a rule, it is preferable to have a solid surface of the facade, which predetermines the requirement that the box be as close as possible to the outer plane of the wall. The considered design for installing window units, according to Schild, is most often the cause of defects that appear in the area of window slopes. In most cases, the gap between the frame and the slopes of the opening is filled from the outside with sealing mastic, which does not lose elasticity over a long period of operation, and from the inside the same gap is closed with strips (platbands) or a special profile, which can simultaneously serve as a beacon limiter for internal plaster. Research has shown that the weak point of the structure is mainly the possible shortcomings of the sealing mastic for filling the seams and negligence in performing operations to seal the seams, namely: - poor-quality installation of the sealant associated with its insufficient plasticity; - the presence of too wide seams; — no pre-treatment of internal joint surfaces with primers; — lack of heat-insulating seal (caulking) in the seam; — loss of the sealing mastic’s elastic qualities (sealant fragility). From the above, we can conclude that when installing window blocks in maximum proximity to the outer surface of the walls, subsequent defects can be avoided only if the measures for sealing joints in areas adjacent to the masonry are provided for by the project and carried out in kind with skill and exceptional care. But even if the connections are made flawlessly, there is also the danger of getting wet due to rain moisture penetrating from the side into the sealing area of the window block, for example, when laying external walls. In addition, if there are window openings without quarters, one should be wary of insufficient thermal insulation in the area of the window slopes. Often you are trying to find a situation with poor thermal insulation; equalize by laying light building slabs on the inside, with the help of which they organize a semblance of the missing inner quarter. It is more advisable to clad the internal slope by filling the gap between the masonry and the facing board with mineral wool; in this case, the adjoining of the window slope casing to the internal plaster of the wall is carried out using fillers or special profiles.

Windows: illbrook-installation when there is no quarter

Good day everyone!

I want to change the windows in my house, I have been looking for a good company with good installers for a long time. But apparently we (Ukraine, Donetsk) don’t have such people. For half a year now I have been carefully inspecting the quality of the installation of all my friends, relatives, wherever possible. Absolutely everywhere it’s the same thing - the work is a mess, the foam is rubbish, 99% of the slopes are simply covered with cement, and usually they don’t even cover the foam on the outside. In addition, everything is done crookedly and clumsily. Therefore, I decided to install the windows myself - I don’t mind the time, I’m getting carried away - but I’ll do it right.

The essence of the problem: a careful examination of the window openings showed that the quarter (street slope) as a phenomenon is completely absent. That is, the opening I have everywhere is square-cornered (the brickwork is one and a half bricks long). There is no overlap on the frame from the outside at all - at the junction of the frame and the wall there is a thin layer of cement grout, which has long since moved away from the frames and there is a gap along the entire perimeter of the window

2mm (between wall and frame).

Question: how to perform a high-quality installation in this case? Where to glue PSUL on the outside? Maybe break out the old window, clean the brick and make quarters? If so, how best to make them (I have only one idea so far - stuff dowels, tie them with wire and fill them with cement). Will the quarter peel off from the masonry over time? What height should I make the quarter?

Related question: I tried to find PSUL and vapor-proof tape on the construction market - so far the result is zero. Apparently they don’t use this in our window business at all. What can replace these materials? Maybe they are used somewhere else besides window installation (well, to make it easier to explain to sellers what I’m looking for)?

Has anyone encountered the problem of quality installers or purchasing PSUL/vapor-tight tape in Donetsk?

I look forward to your advice, thanks in advance!

Installation technology

Today it is necessary to think about any possibilities for saving energy and fuel, reducing useless losses during the operation of consuming devices and structures. Serious sources of energy loss are external walls, roofs and roofs, basements, translucent structures, seams and joints of buildings made in violation of technology and regulatory documentation requirements.

About 8% of all heat loss in buildings occurs at assembly seams connecting window blocks to wall openings. This is a huge amount of burned natural gas, coal and fuel oil that could have been saved! How can we minimize losses through assembly seams and at the same time ensure maximum durability of these seams? The answer to this question is given by GOST 30971-2002 Assembly seams of joints connecting window blocks to wall openings; it regulates all parameters of assembly seams. GOST implies a three-layer construction of assembly joints, where each layer has its own parameters and performs a certain set of functions.

The outer layer of the installation seam protects the insulation from moisture getting into it, protects the insulation from the effects of ultraviolet radiation and helps remove moisture from the installation seam to the outside. The material that best meets GOST requirements for the outer layer of the assembly seam is vapor-permeable self-expanding sealing tapes (PSUL). This material works on the principle of a compressed spring, compensating for any permissible deformations of the window block and window opening. PSUL provides UV protection, waterproofing, but remains vapor-permeable.

The middle layer of the assembly seam plays the role of insulation and sound insulation. Polyurethane foam insulation - polyurethane foam - has received maximum distribution in this capacity. But it needs high-quality protection from climatic and deformation influences.

The inner layer of the installation seam plays the role of a vapor barrier, airtight layer between the warm, humid air in the room and the insulation in the installation seam. For this layer, the main properties are vapor permeability and deformation resistance.

PSUL Robiband

Vapor permeable self-expanding sealing tape. Designed to organize the external level of the assembly seam. Provides waterproofness, protection from UV rays, etc. It is used in various construction seams and joints, but is most often used when installing window blocks.

Vapor barrier tape Robiband VM

The vapor barrier tape is designed to create the inner layer of the assembly seam. Prevents the penetration of warm, humid air from inside the room into the assembly seam and does not allow moisture to escape from the assembly seam onto the slope. The tape is used when plastering slopes, i.e. finishing using wet methods, although it can also be used when finishing slopes with various panels.

Vapor barrier tape Robiband PB

Robiband PB tape is used for vapor barrier of the installation seam from the inside of the room in the lower part of the window block. Remove the protective paper from the tape. Glue the tape with one side to the stand profile or in the fold intended for installing a window sill, and the other to the bottom of the window opening. It is recommended to seal the mounting seam “over the wet foam,” but an option is possible when sealing onto cut foam.

Waterproofing vapor-permeable tape Robiband NL

Waterproofing vapor-permeable tape. It works on the principle of a membrane, allowing passage in only one direction - to the street. It is used for sealing various construction seams and joints, but most often when installing window blocks, under the drain. It can be used when installing a window unit in an open joint (without a quarter joint), but it requires protection from ultraviolet radiation.

The process of installing plastic windows can be divided into several stages: dismantling the old window, preparing the opening for installing a new window, installing a PVC window with complete sealing of all seams, installing ebb and flow sills.

Installing translucent structures is a complex process, on which the level of functionality of your windows directly depends. The specialists of Cascade-Via Company LLC have invaluable experience and qualifications, regularly improve their professional level and undergo certification. During installation, high-quality materials and modern tools are used. Our specialists carry out installation of plastic and aluminum products of any complexity, all work is guaranteed.

All this guarantees you flawless installation of plastic windows, ebbs and slopes at any time of the year!

Finishing slopes “turnkey window”

Finishing PVC slopes is the final stage of work on updating window openings.

Our specialists perform three main operations: finishing the internal slopes, making the final seal of the window sill and sealing the external seam.

Finishing balconies and loggias

We offer you an affordable and at the same time reliable option - glazing of balconies and loggias made of plastic and aluminum. It must be taken into account that glazing a loggia with aluminum structures will not provide high thermal insulation. This is a way to protect a balcony or loggia from wind, snow and rain. PVC glazing will provide a higher level of thermal insulation, but to make your loggia truly warm, you need to think about insulation. This will make it a pleasant place to relax and work and bring comfort to the adjacent room. And our experienced, highly qualified specialists will help you with this: they will carry out work on landscaping your loggia or balcony with high quality, on time and with a guarantee.

What do you need to know?

One of the works associated with the construction of external walls is the design of openings for windows in them. When preparing window openings in brickwork, remember that the performance of the building as a whole largely depends on the quality of your actions. Pay close attention to the situation if the window opening needs to be laid out when finishing walls that have been partially dismantled.

Let's start with a definition.

Even during the factory production of concrete panels for apartment buildings, the panels were cast with quarters of window openings in accordance with all construction canons.

"Window quarter" or quarter in a window opening.

And although there are a huge number of specialists in installing plastic windows, knowing what a quarter of a window opening is is important for the home owner.

Quarters are not provided in doorways.

The dimensions of window openings in brick walls depend on the area of the room and the location of the room relative to the cardinal direction.

It is necessary to plan everything in advance, mark the space for the opening, prepare and install a lintel that will take on the entire load of the wall above the opening, so it must be carefully calculated, taking into account the following factors:

When reconstructing a house or making major repairs, there is often a need to remodel. However, an obstacle to this may be a load-bearing wall, which is extremely undesirable to be introduced into the structure, but is possible if all actions are carried out correctly.

Installation algorithm in an already finished wall

The second option for arranging a window opening involves performing work on an existing wall. The workflow looks like this:

First the marking is done. This stage involves identifying zones for placing jumpers and technological holes. The working stage is carried out using the triangle method, the lintel is marked so that its top is in the lower masonry row;
Having made such marks, fifteen centimeters are added for each edge of the jumper. This distance is necessary to install supports that secure the lintel made of metal structures or reinforced concrete;
installation of the support begins. It is necessary to provide a distance of seventy to eighty centimeters between the load-bearing wall and the supporting element;
as soon as the support is placed, a wooden beam is laid on it, which is necessary to redistribute the load effects;
a mark is made along the outer surface of the wall corresponding to the placement of the beams;
in order to place these marks on the inside of the wall, drill holes into which studs are installed, supporting them on each side with supporting elements;
the next stage is fixing the support. This can be done with ordinary nails, driving them into boards and studs;
Using a hammer and a sharp chisel, the plaster layer is removed from the surface of the wall. The cleared area should correspond to the size of the future window opening. An additional three centimeters are added on each side;
Having removed the plaster material, we begin dismantling the brickwork section. It is best to move from the place where the jumper is located, after that all that remains is to install it;
all protruding bricks are adjusted;
Having finished installing the jumper, use a grinder to make a cut. This will help to level the edges of the brickwork of the opening area, remove irregularities above the window, and facilitate subsequent processing of the slopes;
At this stage, the design is completed, it is allowed to proceed with the installation of the window structure.

Window opening technology

You can make a window or doorway in a load-bearing brick wall without weakening the structure of the structure.

We recommend entrusting all work to professionals, especially if you plan to make an opening in a load-bearing wall.

What can I say: an experienced mason can lay out not only the window areas, but also the entire wall, as it is now fashionable to say: in “3D format”. This is exactly the kind of art, without exaggeration, that we see in the picture above.

In this case, one of the most popular options for framing the opening today is most often used, which is called a “quarter”. In any case, this is the simplest option.

The dimensions of windows, the width of the walls between them, the height of the window sill area - all this is regulated by standards. But even if the dimensions of the openings do not correspond to them, there is no big problem in this - any company today will manufacture window blocks according to individual sizes.

Wooden windows
Window and door openings

1. Openings are made both in stone and in frame and chopped wooden walls, as well as on the side of the opening up to the bottom and in stone, plaster, wooden and other partitions

The openings are made wider than the window frames and door panels by the thickness of the frames. In addition, a gap must be left between the frame and the structure of the stone walls or partitions for subsequent sealing with thermal insulation or other material.

2. In frame buildings, the opening is formed by the appropriate installation of frame posts; in panel houses, an opening is left in the panels, while simultaneously with the manufacture of the panel, a box is installed and the frames or doors are hung.

Layout of decorative elements

As a rule, a window opening in a brick wall starts from the 14th row of masonry. The last one in the window sill area should be the butt row.

When erecting the walls of the designed building, all masonry work is carried out according to the drawings. Surely, there will be no disproportions in such a structure, which cannot be said about houses that are built “by eye.”

Options for laying bricks around windows

So, removing 6 cm of the wall - namely, the size of a quarter of a brick - does not imply any measures to provide support for the lintel. It’s a completely different matter if you need to radically expand an existing window, combine two openings into one - or even cut an opening in the masonry where there was not one originally.

In the modern world, with the development and improvement of window production, large, panoramic windows have become fashionable.

Thus, we remove the load from the old beam and transfer it further to the brickwork. Then you can remove the old lintel and remove the unnecessary part of the wall.

Where is it used?

This building material remains traditional. When constructing all kinds of buildings, a certain type of brick is used. In order to save building materials, it is not advisable to use solid bricks for continuous masonry. It is better to make a solid wall from light and hollow material. Quarter brick masonry is used for the construction of internal partitions of a room. With modern capabilities for the production of building materials, bassoon and facing bricks are produced that are equal in size to quarters of ordinary building materials and are used for external finishing work of buildings and decoration, cladding the foundation.

How to expand a window in a brick house

That is, if you have a beautiful view from your window, then you want to expand the view as far as the building’s design allows.

Whatever tool you use to expand window openings in brickwork, you must not forget about personal safety.

Prepare for the fact that for the sake of a fashionable French window you will have to install an additional reinforcing frame.

One of the most important stages in the construction of a building is the laying of windows; in this case, a certain amount of brick will be required, which will depend on the size of the window. Since a window opening violates the integrity and strength of a monolithic wall, the reliability of operation of the entire house depends on the quality of its execution.

Construction of lintels for window openings

The window opening must be reliably supported, because... violates the integrity of the structure of the house.

Brick windows are laid with the installation of two types of concrete lintels:

A metal channel is one of the popular ways to create a lintel that forms a brick window with a small purlin. A channel is a device that is a corner made of metal, usually 12-14 centimeters in half-brick piers and 24-27 centimeters in whole-brick piers.

First of all, you need to conduct a survey of the premises, inviting specialists to do this. If the house is already old and multi-storey, then due to its dilapidation it is unlikely to be able to obtain such permission. Another situation is when the neighbors above or below have already done redevelopment. Then the new door can only be made on the same level as the one in their apartment. Because placing openings in one wall at different levels can greatly weaken its load-bearing capacity.

To carry out the work efficiently, you will need the following tools:

When you need to strengthen

Most often used for windows of brick buildings:

If a new house is being built, then when drawing up the project, the most suitable method of strengthening door and window openings and arches is taken into account. But there are situations when it is necessary to strengthen the opening in an existing building.

The strengthening technology is selected depending on the thickness of the wall, what material it is made of, and the size of the hole itself. Several options are used to strengthen brick walls:

Arched brick purlin of window opening

To create a decorative element, the brick is made to protrude from the wall by 5-6 cm with the butt side. It is most convenient to make quarters on small steel channels. In addition to its decorative function, quarter masonry improves thermal insulation properties, which reduces the likelihood of drafts entering the house through the window.

Wedge lintels made of bricks

Stages of installing a wedge purlin:

A reinforced concrete block is inserted into the upper part of the window opening, with its ends secured to the brickwork. After installation, subsequent rows of material can be laid.

Installing a purlin in a window opening of a brick structure is the main part of the work. The purlin is a jumper at the top of the window opening, thanks to which windows can be mounted into a brick wall.

Sequencing

The design is measured in a certain sequence:

determination of opening parameters;
determining the internal dimensions of the frame;
calculation of possible deviations from the norm based on the data obtained above;
determining the size of the elevation of the lower part of the window above the plane of the opening;
calculation of frame parameters.

Discuss in advance with the team of window workers what measures will be taken to protect the installation seam from harmful environmental factors; it may be necessary to knock down brick irregularities on the wall or panel. In general, window openings are similar in structure to door openings.
