Foamit can be used as an infill in flat roof structures. Foam glass is lighter than lightweight gravel, and it can provide adequate thermal insulation for the structure. Before compaction, Foamit can easily withstand the loads exerted by people walking on top of it, and the material is easy to handle. Foamit therefore cuts costs on building sites. Foamit also does not promote corrosion.
Foamit can be installed using a lifting bucket and by blowing.
