foam concrete insulation is an insulating material that can be used in buildings and other constructions to reduce the transfer of heat through the structure. The foam insulation can be applied by spraying a liquid onto the concrete surface and it will expand once it dries forming a thick layer that prevents heat transfer from the ground through the concrete. It also prevents condensation and water penetration which can cause damage over time.
Foamed concrete is a kind of light weight concrete that contains a significant amount of air, which makes it very lightweight and therefore does not exert any stress on the sub-structure. It also has good thermal insulation properties, which can save energy and money on heating costs in buildings, as well as soundproofing properties.
In the production of foam concrete, a protein-based or synthetic foaming agent is used to create an air gap inside the cement matrix. The foamed concrete is then cured in the same way as conventional concrete. The type of foaming agent used has a direct impact on the quality and properties of the final product. Protein-based foaming agents produce stable bubbles and allow the use of more air, resulting in a lower density.
Foam concrete has been successfully used as an insulator in various construction projects around the world. The low density of the material means it is lightweight and does not impose any vertical stress on the sub-structure, while the large number of pores provides good thermal insulation. It is also durable and has a good freeze-thaw resistance.
