Foam-Control Direct-to-Deck is a cost-effective, durable, and energy-efficient solution for roof insulation. Molded polystyrene insulation can be applied directly over steel roof decks without the use of a code specified thermal barrier, resulting in reduced material and labor costs.


Foam-Control Direct-to-Deck is compatible with all major roofing materials and assemblies. Additional benefits such as design flexibility, resistance to moisture, and high R-value make Foam-Control roof insulation the preferred roofing solution among Contractors, Architects and Engineers. It is also one of the most cost-effective steel deck roofing insulations on the market.
