Thermal blocks

Choose the warmest wall material which is thermal blocks Betler

Do you want to reduce the cost of heating your home?

Thermal blocks of cellular concrete Betler is one of the most popular elements used to climb masonry exterior and interior walls. Betler is ideal for single-layer walls, has a very high resistance to mechanical and fire. Composition of cellular concrete eliminates fungi, bacteria, mold and other harmful micro-organisms, it is resistant to chemical corrosion.

Wall-layer cellular concrete Betler has the most favorable thermal performance of building materials used in the construction of the walls. Aerated concrete is well insulated, it is resistant to high temperature changes so you notice a lower heat loss and save on heating our homes. Uniform wall made of cellular concrete creates the healthiest climate in the house, as a result of very good humidity control inside the building. Building a house of aerated concrete provides the lowest cost of manufacture of 1 m³wall. Aerated concrete is resistant to biological agents (mold and bacteria).

For the production of cellular concrete raw materials that are used for health: quartz sand, cement, lime and water. Only from cellular concrete walls can be made single-layer thermal insulation complying with the requirements, without additional thermal insulation. The porous structure of AAC makes walls to "breathe". Very good heat storage makes house made of cellular concrete is not sensitive to rapid changes in temperature.

Betler thermal blocks can be cut and make them different size holes for all types of installations. It's an easy job that can be done using simple tools.

Concrete blocks Betler are available with smooth or profiled face "tongue and groove". Blocks with a width of 240 mm and above are the mounting bracket.
