Currently, very high requirements are presented to the construction of houses not only regarding strength, but also regarding the environmental purity of materials. One of these materials that combines environmental friendliness, reliability and strength is foam block. Most often this material is used to build walls in small houses. And if the construction of high houses occurs, then foam concrete is used as a heater for the bearing walls of the building. Penoblock can be used in construction if you took a project of a brick house as a basis. You just need to replace the brick with foam block and continue construction. Such material does not differ in high cost, so when erecting a summer cottage, you will significantly save.
