Modern insulation of windows
After a couple of dozen years of work, any window appears, distortions of structures, clearance and cracks. Drafts appear in the apartment. Of course, the best option in this case is to change the windows to modern – metal -plastic windows. But if this option is not satisfied for some reason, the windows can be insulated and repaired.
First we remove the wings from the loops. Open window opening at this time must be closed with a protective screen. A groove filled with silicone insulation is cut in the sample. Frames are also insulated in the same way. Grands of frames, as well as joints between glass and frame are filled with insulation. Sales are strengthened on frames. They should fit them so that they move freely. It remains to change the bolts, accessories and locks, paint the frames, and the windows are provided for many more years of full work: the minimum service life of silicone insulation is more than 15 years. A rational solution will be the replacement of glass with the so -called “insulated”, that is, covered with a special composition. Glass acquires thermal insulation properties comparable to the properties of the double -glazed window. Another option is to fix on the outer side of the glass with a special film for a hydraulic tank. It is produced on the basis of polyethylene supplemented with fiberglass nets. The film is attached using an industrial stapler. The tightness of silicone joints significantly increases noise insulation, but this may not be enough. One of the options for protecting windows from noise effects is to install a glass of various thicknesses. The sound passing through one thickness of the layer, then through the other, weakens.
