Construction technology has made a significant breakthrough in recent years. This was largely due to the large amount of scientific research in this area.
Many high-quality materials have appeared, which enable the rapid and high-quality construction of houses, the cost of which is much lower than that of the brick traditionally used in this role.
One of these materials is a heat block, reviews of which clearly indicate that the owners of cottages from it were completely satisfied.
Features
In general, here we should make a small "lyrical digression", telling about what it is. So, a composite material is called a heat block, the front side of which is represented by ordinary concrete. More often than not, it does not differ in any frills, but sometimes originally painted versions are released.
In the second row, the heat block, reviews of which we will consider, contains expanded clay concrete. It provides low thermal conductivity. It is this factunderlies most of the positive feedback: the owners are pleased that they began to spend much less money on heating.
In the third layer (in the middle) there is a foam plastic, due to which the heat block is almost comparable to wood in terms of the ability to conduct heat. Needless to say, how positively this affects the thermal performance of the finished building?
Other benefits
Since of the really heavy components it uses only concrete, the heat block, the reviews of which are very eloquent, has a very low mass. In any case, those owners of houses who built them on their own talk about the high speed of construction, as well as the simplest installation, which the same brick does not differ in any way.
You can work with it even in winter, as its low weight and ease of handling contribute to this.
Negative opinion
As it usually happens, there were also "spiteful critics". What are their claims? They say that the laying of heat blocks does not provide proper thermal insulation of the room. Allegedly, the gaps between them turn out to be too wide, which is why it blows in them.
Here it should immediately be said that the blame for all this disgrace lies solely on themselves! The fact is that only the first (!) Row of heat blocks can be laid on a conventional cement-sand mixture. All subsequent masonry is carried out only (!) On a special glue, and all vertical seams on the first row are filled with it.
And more. Any construction from heat blocks involves the application of sealant or glue not only on the front side, but also on the foam layer. Otherwise, you will not achieve normal masonry strength!
Conclusions
What to say as a result? We will stay somewhere in the middle. Yes, the heat block, the reviews of which we considered, really refers to fairly cheap and high-quality building materials. But if you lay it strictly according to technology, then it will take more than one hundred tubes with sealant to seal the seams, the cost of which cannot be called low.
So the final decision on construction is up to you, based on financial capabilities.
