Remember
that there should not be excessive force on the handle when locking the sash, otherwise the fittings will quickly fail or the window handle itself will break. If a large force is observed, then it is necessary to adjust the pressure (usually on the trunnions themselves) by turning the eccentric with a 4 mm hexagon wrench, with pliers in the case of flat trunnions, or, if the manufacturer has provided for this, with a regular figured screwdriver.
Window alteration refers to work to change the opening of a sash or door. These are two types of work. The first is that a blind (non-opening) sash is converted into a turning or tilt-and-turn one, and the second is that a turning sash is converted into a tilt-and-turn one. The alteration also includes work on replacing double-glazed windows in order to increase the noise and heat-insulating characteristics of the window. If you want to restore the original (and now lost) properties of the window, then you need window repair or adjustment of fittings.
Common breakdowns
No matter how high-quality the product is, for some reason it can break. It is important to identify these reasons, then the repair will take place quickly and effectively. To get rid of a breakdown, they call a specialist, but often you can deal with them yourself.
Sometimes on an old plastic product it is necessary to replace the fittings with a swing flap and handles. Like any other, it fails.
In this case, you need to unscrew the old handle and screw on the new one. This part of the profile may jam. Most often this happens in the open position.
Then, check the blocker. It is located on a loop at the top or under the handle itself and looks like a metal tongue. This part is important, since the ability of the structure to work depends on it.
If the sash opens in two positions at the same time, the system must be completely closed. It should fit snugly against the profile, then turn the handle to a horizontal position. Then, the profile will return to its usual position and will be able to open normally.
Don't forget about proper care. To avoid various breakdowns, it is recommended to remove all contraction, clean it from dust and dirt and lubricate it with a special product.
Regular maintenance will prevent rapid wear of the device, which means the system will last for many years.
Changing a pivot window to a tilt-and-turn window.
When performing the work, the entire “piping” of the fittings (all the metal) is replaced with a new one, only the bottom loop remains. It is better to install the fittings of the same brand as the old one, then you will not have to change to a new one and reinstall the top hinge. This is important, since it is not easy to install the top hinge correctly and efficiently without a template, and even in “field” conditions. An incorrectly installed top hinge can become loose over time, especially on large sashes. Which threatens their downfall. It is advisable to find an agreement to determine the brand of the profile system. This is necessary to select “standard” strikers. Cost (including Roto NT fittings) (only plastic windows) - 5000 rubles / sash.
Functions of a modern window
To ventilate and ensure normal air exchange, it is no longer necessary to open the entire window; it is enough to switch it to one of the available plastic window modes.
To ventilate the room, just turn the handle up and the sash will tilt to the desired position.
When the window handle is turned 45 degrees, the micro-ventilation mode is set
Micro-ventilation becomes available by turning the control handle at an angle of 45 degrees from the vertical. This creates a gap of several millimeters, which is enough for fresh air to enter the room. .
Additionally, ventilation can be provided even without unlocking the sash, but for this it is necessary to make changes to the design itself and install an additional ventilation valve.
These functions, as well as full opening and closing, are available thanks to a mechanism that is adjusted when installing the window package.
Converting a fixed window into an opening one.
Before you decide to convert a fixed window into an opening one, compare the cost of this service with replacing the window completely (just don’t forget about the slopes).
If the window is single-leaf and not large, then the amounts can be quite comparable, but the warranty periods for the work will differ. To remake a window - 0.5-1 year, when replacing an entire window - 3-5 years. Fixed (non-opening) glazing can be of two types: 1. Glazing in a frame
- when a double-glazed window is installed in a window frame.
2. Glazing in the sash
- a non-opening sash is installed in the window frame, and a double-glazed window is installed into it. This is done to maintain a symmetrical appearance when there is an opening flap next to the blind one. As a result, a blind sash looks like an opening one, only it does not have hinges or a handle.
Sash glazing. When converting such a window into an opening one, the following work is performed: - reinstallation of the double-glazed window - to remove the sash (it is screwed on with self-tapping screws from the inside) you need to remove and then reinstall the double-glazed window, - installation of locking fittings (trimming) and handles, - installation of hinges. This is the most responsible job. Why, it is said below. It is advisable to find an agreement to determine the brand of the profile system. This is necessary to select “standard” strikers. Cost (including Roto NT fittings) (only plastic windows) - 6000 rubles / sash.
Glazing in frame. This is more labor-intensive and expensive work. It should be trusted to trusted performers. It is highly advisable to find the contract to find out the name of the profile system. The sash must be of the same system or its complete analogue, otherwise there will be problems with blowing or difficulty (physical effort) in turning the handle. It is not necessary to choose the same brand of locking hardware for a new sash, and it is even advisable to install a new one, then there is less chance that it will soon be discontinued. But it is better to choose high-quality fittings: Roto, Mako, Ziegenia, Winkhouse. When installing fittings, the main attention should be paid to fastening the hinges. This needs to be done according to a template. The hinges have special supports; they support the weight of the sash,
therefore, the counter holes for them must be drilled with high precision, otherwise the weight of the sash will be supported by the self-tapping screws, and their purpose is different - to press the hinges to the frame. Combining these appointments will inevitably lead to loosening of the hinges and, possibly, the fall of the sash.
You should also be prepared for some possible inconsistencies: 1. The tone, gloss, “structure” of the surface of the new sash will most likely differ from the existing ones. 2. The following may differ: welds in the corners of the sash, spacer frames of double-glazed windows, geometry of glazing beads, glass tone if it is not completely transparent.
Cost - we don't do it.
Sash replacement procedure
Provided that competent specialists are involved, the active sash of a plastic window can be installed very quickly without any problems.
When upgrading, there is no need to cover furniture and interior items with films, since no debris is generated during the replacement. The whole process looks like this:
- The blind sash is measured.
- Based on the data obtained, a new element for the old window is manufactured in the workshop.
- At the agreed time, the product, completely ready for installation, is delivered to the address.
- The old glass unit is removed from the frame.
- Fixing elements for the mosquito net are attached to the outside of the window.
- In the vacated opening, window hinges are fixed onto which the active sash is hung.
- The fittings are adjusted and checked.
At the end of the work, it is recommended to check the tightness of the window and the tight fit of the new sash. For the easiest way to do this, read on OknaTrade.
Replacing a conventional double-glazed window with a double-glazed window with heat-saving glass.
At the beginning of the development of the window market in Russia, many, out of ignorance or because of cost savings, preferred a single-chamber (two-glazed) double-glazed window to a double-chambered one, or installed windows with a double-chamber (three-glazed) double-glazed window, but with a thickness insufficient for our climate zone. Now people have become convinced of the shortcomings of this preference and are striving to correct the mistake. There are two ways to solve this problem: The first is to replace the old double-glazed window with a new one of the same thickness, but with heat-saving (low-emissivity) glass. The second is to replace the old double-glazed window with a new one with a greater thickness (possibly with heat-saving (low-emissivity) glass). In this case, you will have to change the glazing beads to beads of smaller thickness, but problems may arise with this: 1. The profile from which your windows are made may no longer be produced, which means there are no glazing beads, so before deciding to replace the double-glazed window with new one with more thickness, make sure that the contractor has the required glazing bead in stock. 2. It is important that the new beads are no longer than required, otherwise, during installation, they may split the sash at the welded corners.
