Direct-to-Deck EPS Roof Insulation

About Direct-to-Deck Roof Insulation


Direct-to-Deck expanded polystyrene (EPS) is a cost-effective, durable and energy-efficient solution for roof insulation. With the release of ICC-ES Evaluation Report ESR-2043, expanded polystyrene (EPS) roof 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.

ACH Foam Technologies’ Direct-to-Deck EPS roof insulation is compatible with all major roofing materials and assemblies. Additional benefits, such as design flexibility, resistanceFoam-Control EPS Roof Insulation to moisture and high R-Value, make ACH Foam Technologies' EPS roof insulation the preferred roofing solution among Contractors, Architects and Engineers.
