Do I need to insulate the house of hollow porous ceramic blocks

Many people faced with the loss of heat in the house. When construction is necessary to pay special attention to resolve this trouble because the heat loss occurs not only through the walls, and windows, roof, basement

The first thing to decide on materials for construction, and then select the appropriate proper construction to keep warm in accordance with standards for energy efficiency.

Question often arises when using hollow porous ceramic blocks - whether you need to insulate the walls by using such blocks? To get the correct answer, you should find out what the width of blocks used and how they were built.

The walls in the construction of hollow porous ceramic blocks are divided into two types: single-layer (consisting of some blocks) and multilayer. The latter, in turn, are subdivided into two-layer (block and insulation), and three-layer (block, insulation and facing brick). For the erection of single-wall units are used most frequently width 38, 44, 50, see Concerning the insulation, we can say that insulate these walls are not appropriate, since the material has a sufficient coefficient of heat transfer resistance. Of course, if the construction does not belong to the class - the economy, and the climatic zone is from the favorable, then why not insulate.

Sometimes they build a wall of porous ceramic blocks width of 25 cm and 30 cm are mainly happens when construction work is already underway, and wall material is not already selected. The walls of the ceramic blocks better insulate slabs of mineral wool, which have good water vapor permeability. For wall insulation fastened to the glue or dowels, so that it tightly to the wall surface. Further walls made of your choice, such as outdoor decorative plaster, clinker brick, siding, wood. With regard to the thickness of the insulation, then the unit width of 25 cm it is 100 mm, block width 30 cm - 60 mm.

Another important point to consider when insulation of houses - is the use of masonry blocks with a "light" ("warm") masonry mortar. In this solution also has a cement, which acts as a binder. As an insulation material - filler used - expanded clay or perlite sand. If you replace the cement - sand mortar "easy", then the wall will improve thermal performance by 17% due to the large difference in thermal conductivity of these solutions. By "easy" mortar may include dry hydrophobized building a mixture of mineral binders and mineral fillers, including perlite. When mixed with water it forms a homogeneous gray mass. This solution is designed for laying and connecting walls of the blocks with high thermal insulation properties. Mortar is recommended to apply to the tile layer thickness from 8 to 15 mm.
