Old proven methods of insulation of wooden windows with foam rubber and paper have served for decades. Until as long as in the distance did not loom "Swedish technology of insulation" windows. What is the appeal of this technology and will the costs for insulation measures be justified, it is better to immediately buy a new PVC window?

The history of the emergence of "Swedish technology"
The emergence of the "Swedish technology of warming" we owe the history, and more specifically, the retreat of the French and Swedes in December 1812. It was then, in the severe Russian frosts and under the powerful onslaught of Kutuzov's army, that the enemy retreated swiftly. To warm, in the course were any warm clothes, including blankets, as well as found boots and sheepskin coats.
Therefore, the concept of "Swedish technology" sounds rather skeptical overtones. Naturally, the technology of warming the windows with a hollow tubular heater, the Swedes have nothing to do. What, even a very poor Swede, will come up with the idea to insulate the old, swollen from time and weather window 10-15 years of age? Yes, no! Home-grown technology can be considered a national miracle. Our miracle.
But the approach of winter does not care about the lack of money from the owners of old windows. I'll have to use any way to warm the windows and doors.
A new kind of Swedish technology TLT (Thin layer technique) has proved by testing ISO815 that the properties of the new product significantly exceed the previously existing methods of insulation.
Than it is really possible to warm an old wooden window?
Struggle for Degrees
Natural savvy and diligence more than once rescued humanity in serious trials. Broken windows of apartments were pasted with strips of thick paper, welding glue according to an old recipe. For two hours the family diligently "glued" the windows in two layers with paper tape. Do not hide it, it was warm. But whether the paper is over for humanity, or whether the paste is lost ...
Therefore, the technology of window insulation has acquired other dimensions and methods. In place of paper and foam rubber came sintepon, silicone and mortise heaters Euro-Strip.
Distinguish the following household sealants, intended for insulation:
• one- and two-component seals for doors and wooden windows
• Seals for doors of metal
• Mortise heaters Euro-Strip.
The sealed seal and the size of the profile should ensure free movement of the window leaflets and a good seal.
silicone sealant
Silicone miracle can be confidently called the best our time. Soft and flexible structure of silicone is suitable not only for the insulation of cracks in the windows. Manufacturers of silicone claim that the silicone sealant will last two decades. It is sufficient to select the required diameter of the insulation under the slit.
For slots of windows of any width there are sizes of the sealant from 5 to 12 mm. In this case, it is necessary to remember the ability of a hollow heater to keep the shape.
This means that the sealant inserted into the slots and slots instantaneously acquires the original shape. By the way, the profile of the sealant can be not only of round shape. Let's say that traditional Chinese gaskets will last a couple of seasons.
But not a high-quality sealant brand Euro-Strip, which is inserted into the prepared groove. Silicone single-channel tube, seated in the seam, is not afraid of frost, heat, dust and moisture.
two-component gaskets
For the industrial production of two-component heaters for the insulation of windows in Swedish technology, porous EPDM is used, with excellent resistance to ozone and UV radiation. Such improved qualities were achieved by applying an additional protective layer, which allows the sealant to be used in the temperature range from minus 40 ° C to plus 70 ° C.
mortise seal Euro-Strip
The mortise seal can be made of such materials:
• EPDM
• Silicone rubber.
EPDM or a copolymer of propylene, ethylene and diene monomer is considered the best * window insulation material. The material has the following technical parameters:
• maximum resistance to weathering
• Mechanical structural "memory" for the preservation of the original form
• pores with closure, ensuring watertightness
• Self-adhesive profile.
In accordance with the Swedish technology of insulation on the old wooden frame, it will be necessary to mend a groove where the heater will be placed.
For grooving the groove, special equipment is used - a hand mill equipped with a high-speed end mill.
We make our own insulation according to Swedish technology
stages of insulation
The process of window insulation will consist of the following stages:
• Removing the window leaf
• Preparing the frame for packing the sealant
• scraping the places of grains
• milling of the technological groove for laying
• rolling up the seal into the formed groove
• cleaning glass from paint residues
• processing seams glass sealant
• Installation of the leaf in place.
milling groove for sealant
The groove on the inside of the frame must be selected for the height of the seal. It is preferable to place the recess near the valve line. Milling of the groove is made around the perimeter of the leaflets prepared for insulation.
how to roll up the sealer with your own hands
The technology of laying the seal is simple, like three pennies. Take the roll of the sealant (the sealer is sold with rolls) and cut off the necessary ribbons. Then the sealant is inserted into the prepared groove with antennae inside and tightly rolled.
The process of window warming is shown in detail in this video.
All of the above seals, as practice shows, are able for several seasons to provide a warmed room with a temperature increase of 3-5 degrees. Is the thermal insulation in the economic plan justified by Swedish technology? Severe Russian winter will judge, as then, in 1812.
