What if there is no money to replace the windows, or are the old windows still in quite a good state, and only in places there are crevices? The solution is - heat the windows using Swedish technology. You will spend a minimum of money( 5-7 times less than on new windows), and in return you will forget about drafts, frozen glasses and noise from the street. You can further reduce costs by making the insulation yourself.
Technology
The very name of this method of insulation came from the fact that the original tubular seal - the main component of the technology - was of Swedish manufacture. Now the market has many analogues of not worse quality, but much cheaper in price. The name has stuck firmly.
"Swedish" insulation - a hollow, highly elastic tube of rubber rubber, the most common version of EuroStrip from the company Trelleborg. It is very flexible, withstands large temperature changes, is resistant to ultraviolet radiation. It fills all the cracks or shrinks into a thin layer depending on the specific window and blocks the penetration of wind from the street. The sealant itself can be washed, dyed. Even with a sufficiently active operation it will last for 10-15 years.
In addition to installing the sealant, adjust the flaps, align them, if necessary - re-align( this is described here).Fix the glass itself in the frame, seal the cracks under the windowsill. If the binders are double, clean the space between them and make up the cracks.
Restrictions Almost any window can be warmed by Swedish technology, except for those that have completely rotted from time to time. To warm the warped windows, with sagging doors and broken hardware, is problematic. It's easier to put plastic.
The work on insulation is best done in summer or early autumn, as the window will remain open for several hours, and in case of painting and longer.
Material and tool
It is worthwhile to fight for self-sealing if you have the experience of carpentry and the corresponding tool. You need to make channels in window bindings, so you need a cutter. Do not do without a screwdriver, chisel, plane and sandpaper( or grinder).If you plan to paint, then you need a building hair dryer, a primer, paint on wood, a roller and a brush. Of the consumables needed:
- interframe seal,
- tape EuroStrip( or similar),
- transparent silicone sealant,
- putty on wood or mastic.
The required number of seals can be calculated by measuring the perimeter of all the flaps.
Preparation of
First of all, you need to remove the hinges from the hinges. Inspect loops, ties, bolts and bolts, and specify whether they need replacing. If the paint on the window is old, leaves in places or is unevenly applied in many layers, it is better to remove it. The easiest way to do this is by warming the area behind the site with a construction hair dryer and taking off the paint using a chisel. Cleaned frames and doors are planed by a plane, if previously poorly closed, sanded. Scratches and depressions on the wood can be puttyped.
Thermal insulation of windows
If the doors are cleaned of paint, then they are painted again, and when they dry, they are collected. Between the frames insert interframe seal. It protects the space between the doors from dust and serves for additional insulation.
The flaps are then twisted, and along their perimeter a thin groove is cut through the milling cutter, into which the EuroStrip tape is laid. You can not make a groove, but paste the tape on a tree, but in this case it wears out faster, and it will not be so tight.
Glasses in the areas of abutment to the frame, the joints of the bezel with the frame are glued with silicone sealant. This is done to prevent moisture from getting inside and improve noise insulation. Also, the sealant is laid in the gap between the window frame and the wall. Large slots are easier and faster to seal with mastic or putty. The voids and crevices under the window sill are frosted with mounting foam.
The doors are hung on hinges, adjusting the fittings. If everything is done correctly, then the window closes easily, and the handle rotates effortlessly. You can check the quality of the seal by passing a lighted candle around the perimeter of the window and all the doors. If the light does not deviate, then the wind in the winter will not blow in the gap.
Windows, insulated by Swedish technology, are almost completely sealed. To ensure that fresh air is supplied in sufficient quantities, it is better to install a fresh air supply valve under the window.
