Flat EPS Roof Insulation

About Flat EPS Roof Insulation

ACH Foam Technologies' Flat Roof Insulation provides high long-term R-Values and saves labor installation time. Suitable for use with all roofing membrane materials, expanded polystyrene (EPS) roof insulation is compatible with loose-laid and attached single-ply membranes, conventional built-up roofing or modified bitumen systems.

Flat Roof Insulation is unfaced EPS and is suitable for use with loosely laid single-ply membranes. Flat EPS Roof Insulation is also used with conventional BUR and mechanically or adhesively attached single-ply and modified bitumen membranes when field-applied cover boards are used. 

Foam-Control® PLUS+® Flat EPS Roof Insulation

Foam-Control® PLUS+® is an architectural insulation product line with high compressive strength, stable R-value, and superior moisture resistance. Foam-Control PLUS+® is a premium grade insulation manufactured to provide architects, specifiers, distributors, and contractors all the features and benefits inherent in a high quality architectural insulation.

• High compressive strength of 15, 25, 40 or 60 psi
• High R-value that never changes and is stable over time
• Closed cell insulation with superior moisture resistance
• High drying potential to rapidly release absorbed moisture
• Meets code requirements for direct-to-deck
• No thermal barrier required (see ICC-ES ESR-1006 and UL ER11812-01)

Foam-Control® PLUS+® Flat EPS Roof Insulation Outperforms XPS and Polyiso

• Foam-Control® PLUS+® provides more R-value at a lower cost
• XPS and Polyiso use blowing agents that cause R-value loss over time
• Polyiso loses R-value during cold and extreme high temperature exposure
• Foam-Control® PLUS+® available in 15, 25, 40, and 60 psi strengths at a lower cost
• Foam-Control® PLUS+® has a superior drying potential
• Foam-Control® PLUS+® is more vapor permeable to help avoid moisture problems

Foam-Control® PLUS+® & Foam-Control® Flat EPS Roof Insulation

Foam-Control® PLUS+® and Foam-Control® Flat EPS Roof Insulation are recognized for use in direct-to-deck applications.  UL Evaluation Report ER11812-01 and UL Roof Deck Construction No. 458 recognize Foam-Control® PLUS+® 150 up to 6.7" and Foam‑Control® 100 up to 10” being installed directly over steel roof decks along with a Class A, B or C roof covering of 80 mils or less.

ICC-ES Evaluation Report ESR-1006 recognizes Foam-Control® PLUS+® 150 up to 6" and Foam-Control® 100 up to 9” to be applied directly over steel roof decks along with a Class A, B or C roof covering of 45 mils or less.

Manufacturing procedures for roof insulation that are identified in quality control manuals include: material tracing, in-plant testing of product, random sampling of product by outside independent laboratories and labeling of finished product for in-field identification.

ACH Foam Technologies’ quality assurance program is the most comprehensive in the expanded polystyrene (EPS) roof insulation industry. It allows for complete code compliance, certification to critical physical properties and roof listings from UL, FM and others.

ACH Foam Technologies' Flat EPS roof insulation is recyclable and environmentally friendly. It contains no CFCs, HFCs, HCFCs or formaldehyde, and it comes with a 50-year thermal warranty.
