Which foam block is not suitable for building a house

The foam block is an environmentally friendly material that is suitable for low-rise construction. Due to its lightness, shape and technical characteristics, it is possible to build a house from a foam block as quickly and economically as possible.

Before choosing building materials, you need to pay attention to such an indicator as density. This is because one type of block can be used for the construction of load-bearing walls, and the other is suitable only as an additional insulation on the inside of the house.

How to choose a foam block for construction?

If the task is to build a house from a foam block, you need to give preference to a material having a density index from 600 to 1200 units. The best choice for the construction of a two-story house will be a material with a density of 900 units.
As for the dimensions, standard blocks of 20x30x60 cm are suitable for external walls, and for installing partitions it is better to choose 10x30x60 cm.

Another important selection criterion is the hardness of the material. So that the walls can withstand loads and not let cold air into the premises, it is recommended use foam blocks with a hardness index ranging from 2.5 to 7.5 units.

It is worth paying attention to the fact that this material is one of the few hardening over time. Thanks to this, the house becomes stronger and more stable every year.

How to determine the quality of foam blocks?

Many beginners are interested in the issue of how to determine the quality of the building material and gain confidence in its reliability and durability. This is easy to do, without even having special skills in the construction industry.
When choosing, you need to pay attention to the uniformity of the texture of the foam block. To do this, it is necessary to study the block in the context. Small air bubbles indicate that the material has an increased level of strength and can be used for the erection of load-bearing structures. If in the section you can see a large number of volumetric cells, then such blocks are best used for additional thermal insulation of the house. They have a lower density, can not withstand heavy loads, but they can maintain the set temperature in the house and isolate the premises from extraneous sounds from the street.

You also need to pay attention to the color of the foam block. High-quality material is gray, similar in shade to concrete. Lighter shades may indicate incorrect manufacturing techniques.
