Aerated concrete blocks have different density: I use less dense to warm the structure, more dense — for construction.
The characteristic features of foam concrete are excellent thermal insulation, fire safety and efficiency. Like aerated concrete, it has different density and various areas of application. It is preferable to build monolithic walls from it. However, it has a significant humid shrinkage and lower strength. Nevertheless, foam concrete has low moisture supply and does not require protection by plaster or lining material.
