Constant moisture is fraught with the appearance of mold in the rooms. INSULATION INSIDE WALLS Exterior insulation increases the life of the building, preventing the formation of mold, increases energy efficiency, acoustic and waterproofing the walls, and, moreover, is not "stealing" living space. To insulation was effective, you need to keep the consistency and density of layers. Water vapor can come out only if the vapor-permeable to the wall itself, and water vapor permeability of each layer in sleduyushego inflicted on her, will be greater than the previous one. INSULATION WALL OUTSIDE heat flows away through all the building envelope at home: windows, walls, basement, roof, basement, doors and even through the ceiling. This process is influenced by two factors: the difference temperatures indoors and outdoors (loss is greater than the figure above), as well as insulating properties of building envelopes.
The greatest heat loss (30%) were in the walls, as compared to other structural elements they have the largest square. Filed under: Stephen M. Ross. Cold bridge – a piece of outdoor home construction, which is characterized by a low, that is the worst insulated than the neighbors. Such weak and vulnerable portions of the building is considered to be the joints of the walls with a roof and foundation, ledges, windows and doors, any place to fix these or other structural parts of the building to the box. administrator. Cold bridges – an extremely undesirable, as a point cause cooling surfaces. As a result, in places such condensation can occur, appearing fungus and mold. The recommended thickness of insulation material and thickness of exterior walls, mm Insulation thickness, mm reinforced concrete, sand-lime brick 230 150, 510 100 Clay bricks, hollow ceramic 510,100 bricks, 510 100 Bruce (pine or spruce), 150 100 Bruce (Pine or spruce), 200 50 underground poverhnsti in need of insulation and ground surface, in particular foundation. On its walls and slabs lie all the constants (weight of structures and finishing materials) and variable loads (the weight of snow, people, pressure, wind). Heat insulating materials in contact with the ground, must be resistant to moisture and mechanical damage. The best solution for this case is extruded polystyrene. It has good insulation material, waterproof and strength characteristics.
