According Senin walls in the house are a variety of functions: these are elements of the supporting structure, thermal and sound insulation, protection from rain, etc.Consider just one aspect - how to design a wall of the house to be warm.
best thermal insulator is air.The more air in the insulation, so that insulation is less dense, lighter and "warm".The main enemy of any insulation - moisture, it impairs thermal insulation properties, as water - a good conductor of heat.Therefore, insulation is necessary to protect against moisture, and protect both sides.
Firstly, the outside of the wall damaged by water (rain, snow), the wall gets wet and ceases to be "warm".Protection against water is waterproofing.
Secondly, the inside space of the wall falls pairs - the same water, but in the air, with the same unfortunate consequences.
protection vapor is steam.Steam occurs indoors because human breathing, digestion, cooking, drying etc.The vapor always moves from warm to cold.Some of the
consider several types of walls and evaluate their strengths and weaknesses.The walls will be considered in layers, as it were, in the context, in the direction of the room to the street
room - wood - the street.
good solution.Because of the high vapor permeability of wood steam comes out.The house is warm and fuzzy.Ventilation is desirable, especially in insulating glass units.The sensation of "breathing walls".
disadvantage - the wall is not protected from rain, wood rot, becomes wet, the wall is no longer a "warm".
room - wood - facing brick street.
bad, though a popular solution.Dignity - protection of wood from rain.Disadvantage - pairs from the room, passing through the tree comes to bricks and he a vapor.Hence, the moisture from the steam remains in the wood.Wood gets wet and rots, the wall ceases to be warm.How to rectify the situation so that at least the wall is not mokla?On the side wall of the room upholster glassine or other vapor barrier.Because of the high humidity in the room there is no feeling of comfort possible mold on the walls, condensation on windows and pipes of cold water.Room ventilation is required, especially in insulating glass units.
room - wood - foam - facing brick street.
Same as item 2, only warmer wall.
room - wood - air zazor5-8sm-facing brick street.
good solution if masonry diagonally in the upper and lower corners of the wall to make the opening.The circulating air in the gap will make steam outside through these openings.Room ventilation is desirable, especially in insulating glass units.The house is warm and fuzzy.This is the "fashion" is now "ventilated facade".
room - wood - fiber insulation (URSA etc.) - The air gap (5-8) cm siding street.
excellent solution.Same as in claim 4, only a wall is easier, and heat.The fibrous insulation should not interfere with air circulation in the air gap.
room - foam block - facing brick street.
According to its thermo-physical properties of the foam block is close to the tree.Therefore, the same as in claim 2.
room - foam block - air zazor5-8sm-facing brick street.
Same as in claim 4.
warm and light, but the vapor barrier wall made of concrete with Styrofoam (polystyrene) insulation.Same as in claim 2.The feeling of comfort in the room is only possible if effective ventilation (sometimes with electric forced) to remove excess moisture.The house should have a special plan to ensure adequate ventilation.
