How to glue the foam to the wood is the most reliable

Is good foam?

Tree - a material that "breathes" and is the main advantage of wooden houses.Therefore, there are doubts about the warming of the house from a tree foam.Some people argue that it is possible and necessary to do so, while others believe that the foam under the tree will begin to rot.However, experts argue that it is possible to do, but "breathing" insulation.Otherwise, you are depriving the building of its advantages.

There is a rule that states: vapor permeability of materials towards the outside must be increased, so as not to obstruct the exit of moisture out.If we neglect this rule, on the border of dense material will condense moisture, which comes out of the room, which regards to the formation of condensation and rotting wood.Therefore, the water vapor permeability - a very important factor when choosing insulation.

foam has a water vapor transmission rate lower than wood, so it is not the best option for warming.But the organization of high-quality ventilation system the amount of escaping steam will be minimal, hence, will not harm him.Therefore, if you have a well-designed ventilation, the foam can be used for thermal insulation of a wooden house.

Important!In no case do not use this material for thermal insulation of buildings and buildings with high humidity (bath, sauna, kitchen, and so on).

installation process

Before starting the insulation necessary to check all joints between the logs or timbers.If the insulating material is uneven, then update it and fill voids with foam.Next to the wall vertically nailed boards - so that its outer surface is flush with the wall plane.If need be, then this would require separate log abate.At the center of these boards nailed slats, which will serve as a framework.Step installation rails should be 5 millimeters less than the width of the insulation.

Next foam is inserted into the frame from the bottom.If the frame is sustained right away, then the material will be retained therein by interference.If the paper will fall out, they must be secured with wedges of foam or nails.The main condition is that there are no gaps between them.Further material is placed diffusion membrane.Fastened it stapled and glued seams with tape.You can then bind the selected wall facing material.

Important!When mounting the diffusion membrane carefully read the instructions for use, so that it is adjacent to the right side of the heater.

The foam glue to the tree?

figure out how warm the house with foam, it is necessary to elaborate on the methods of its fastening.There are several ways to do this:

• mount between the crate due to tightness (as described above);
• Installation special nails (fungi);
• Fixing using adhesives;
• mount assembly foam.

use special nails - it is a common practice when installing the heater, because they firmly hold the sheets.But it has a drawback, which is necessary putty all the places where the nails are hammered.It is also necessary to take into account the fact that metal nails will act as an additional bridge for the cold, because the metal is a good conductor of it.To solve this problem, you can use plastic molds.

Adhesives do not have problems like nails, but when they are selected have to be very careful.Thus, the adhesive must necessarily be resistant to moisture and temperature changes, otherwise it will be useless.Most often used for this mortar with addition of an adhesive.Regarding the foam, it is rarely used for mounting, mainly it is needed to fill all the gaps.

Tip!It should be noted that the most effective way of fixing is considered a "landing" pages on the mortar and further strengthen their nails.
