Penoblock is truly unique material — in its characteristics it is similar to a tree, relatively excellent thermal insulation, but unlike wood is not at all afraid of high temperatures and open fire. These qualities are valued by both professional builders and homeowners, and that is why the projects of houses and cottages from foam blocks are so in demand in our time. From foam blocks, houses are built on average not higher than three floors, the floors are also built from the plates of foam concrete, which are not inferior in strength to ordinary reinforced concrete, but at the same time much lighter and warmer than these.
