Once the resin and foaming agent meet, the setting process begins to occur – but not too quickly – allowing the fresh foam to be at a free flowing state.

The other big difference is the safety equipment needed by the installer, who is using the product. In recent testing, vermiculite masonry insulation used in a standard 8″ lightweight block performed better than urea formaldehyde foam polystyrene beads, and polystyrene inserts.
Once in place, this product has very minimal settling properties. This eliminates the use of heavy and expensive masonry units used to obtain these ratings in the past. Annual savings in heating and cooling frequently exceed the initial cost of the masonry insulation thus providing a constant reduction in utility bills for the life of the building.
