Foam Concrete Gravity Wedges as a Thermal Insulation of Flat Roofs

Abstract:

Proper selection of thermal insulation materials is an essential part of almost any construction project, whether it is a new construction, renovation or revitalization. There is a large number of materials available on the market and it is often very difficult to have a good grasp. Though some material has very similar features, they often cannot replace each other. The same applies to single-shell flat roofs. So far the most often used thermal insulation boards are from polystyrene and mineral wool. Their installation is accompanied by a large volume of waste. The experimental part deals with the general assessment of the behavior and properties of foam concrete. This allows simplification of technology of thermal insulation laying. Besides the construction speed up and the overall cost reduction the improvement in mechanical properties of the roof structure has been achieved.
