Roof Insulation

Flat Roof InsulationACH Foam Technologies has been producing quality EPS roof insulation for more than 30 years. ACH's EPS roof insulation is reliable, cost-effective and compatible with major roofing materials and systems.

Expanded Polystyrene (EPS) stands the test of time, and EPS roof insulation is a proven performer in roofing applications. Field studies of EPS roof installations that are 20 to 25 years old and older show that EPS roofing insulation performs well in roof applications.

EPS roof insulation has no thermal drift and does not use blowing agents that diffuse out of the insulation. EPS roof insulation R-values remain stable over its entire life without loss of R-value.

Roof Drainage

ACH EPS Tapered Roof InsulationACH Foam-Control™ Tapered Roof Insulation was developed more than 30 years ago with a dual purpose: to drain and insulate dead-level roof decks. Lightweight Foam-Control™ EPS is a value-engineered system that has been proven in new and reroof applications all over the country.

The roofing industry accepts that membrane performance and roof drainage go hand in hand. Membrane manufacturers will not guarantee the performance of their system without positive drainage, and building codes mandate positive roof drainage.

Simply stated, all single-ply, modified bitumen and BUR roofing membranes are less likely to leak and fail if water is not standing on top of them. Potential water damage to the building and its contents is thus eliminated. ACH Foam-Control™ EPS Tapered provides the drainage and insulation necessary under all commercial roofing systems and has been used successfully in millions of square feet of single-ply, modified bitumen, and built-up roofing. ACH Foam-Control™ Tapered Roof Insulation is a great solution for low slope roofing.

Also, pre-engineered factory cut cricket and saddle systems provide effective and economical drainage on structurally sloped roof decks.
