Polyiso Roof Insulation
• Designed for use in practically any low-slope roofing application, including BUR, modified bitumen, and single-ply systems
• EnergyGuard™ Polyiso and EnergyGuard™ NH Polyiso both provide the highest R-value per inch compared to non-polyiso types of insulation of equivalent thickness
• Offers various facers and compressive strength options depending on your specification needs
• Low water permeability means a lower overall perm rating than many conventional insulation boards
• Product’s light weight makes material easy to handle on the jobsite and fast to install
• Easy cutting in the field provides simplified fabricating on the roof deck, minimizing on-the-job damage
• Manufactured with EPA-compliant blowing agents containing no CFCs or HCFs
• Has zero ozone depletion potential (ODP) and negligible global warming potential (GWP)

EnergyGuard Polyiso
EnergyGuard™ Polyiso provides a higher R-value per inch compared to non-polyiso types of insulation of equivalent thickness, making it one of the best thermal solutions for your property.
EnergyGuard™ NH Polyiso also provides one of the highest R-values per inch compared to non-polyiso types of insulation of equivalent thickness. In addition, EnergyGuard™ NH Polyiso provides all the same features and benefits of EnergyGuard™ Polyiso but does not contain any halogenated flame retardants — making it an ideal choice for a sustainable building design.
• Ideal for projects that require higher R-value and a stable substrate
• Provides an economical solution — high insulation value for your dollar
• Pre-consumer ranges from 3% – 9% and post-consumer ranges from 10% – 33% depending on thickness. Total Recycled Content ranges from 14%–45%
• Available in thicknesses ranging from 1.0" to 4.6" (24.5 mm to 116 mm)
EnergyGuard Ultra Polyiso
EnergyGuard™ NH Ultra Polyiso Insulation provides the highest R-value per inch compared to non-polyiso types of insulation of equivalent thickness. In addition, EnergyGuard™ NH Ultra Polyiso provides all the same features and benefits of EnergyGuard™ Ultra Polyiso but does not contain any halogenated flame retardants — making it an ideal choice for a sustainable building design.
• Suitable for buildings with high humidity and roofs that are exposed to excessive moisture, including fitness centers, hospitals, and data centers
• Coated glass-fiber facer reduces potential for mold growth compared to paper-faced boards*
• Offers an alternative to a paper facer; coated glass-fiber facer reduces adhesive absorption and helps to improve nail pull strength
• Available in thicknesses ranging from 0.5" to 4.6" (12.7 mm to 116 mm)
* GAF warranties and guarantees do not provide coverage against mold or other biological growth. Refer to gaf.com for more information on warranty= and guarantee coverage and restrictions.
EnergyGuard™Barrier Polyiso
EnergyGuard™ NH Barrier Polyiso provides all the same features and benefits of EnergyGuard™ Barrier Polyiso but does not contain any halogenated flame retardants — making it an ideal choice for a sustainable building design.
• EnergyGuardTM NH Barrier Polyiso is the first non-halogenated polyiso board that achieves up to an ANSI/UL 790 Class A roofing fire rating over a wood deck with just 1" (24.5 mm) of insulation
• EnergyGuardTM Barrier Polyiso achieves up to an ANSI/UL 790 Class A roofing fire rating over a wood deck with just 0.5" (12.7 mm) of insulation
• Consists of a coated glass-fiber facer that reduces the potential for mold growth, as compared to paper-faced boards*
• Available in thicknesses ranging from 0.5 – 4.6" (12.7 mm – 116 mm) for Barrier Polyiso and 1" – 4.6" (24.5 mm – 116 mm) for NH Barrier Polyiso
*GAF warranties and guarantees do not provide coverage against mold or other biological growth. Refer to gaf.com for more information on warranty and guarantee coverage and restrictions.
EnergyGuard HD/HD PLUS Polyiso
EnergyGuard™ NH HD and NH HD PLUS Polyiso Insulation provide all the same features and benefits of EnergyGuard™ HD and HD PLUS Polyiso but do not contain any halogenated flame retardants — making them ideal choices for a sustainable building design.
• Ideal for low-slope roofs with high foot traffic or that are prone to hail events;*also suitable for metal retro-fit applications
• Offers R-value of 2.5, higher than any non-polyiso type of cover board
• Coated glass-fiber weave provides increased moisture resistance
• Available in 0.5" (12.7 mm) thickness
*GAF warranties and guarantees do not provide coverage against traffic (except where GAF walkways are applied) or hail (unless additional puncture coverage is purchased on eligible jobs). Refer to gaf.com for more information on warranty and guarantee coverage and restrictions.
EnergyGuardTM NH Polyiso Products
All EnergyGuard™ NH products use non-halogenated flame retardants, making them ideal for your sustainable building design projects. Now you can pursue certifications under a green building rating system, such as LEED® v4 or Living Building Challenge, to create a more sustainable roofing system.
• Ideal for practically any low-slope roofing application, including built-up, modified bitumen, and single-ply roofing systems
• Unique and innovative chemical composition of non- halogenated flame retardants helps in attaining green building certifications
• EnergyGuardTM NH Polyiso and EnergyGuardTM NH Ultra Polyiso both provide the highest R-value per inch compared to non-polyiso types of insulation of equivalent thickness.
EnergyGuard™ Tapered
We offer a full line of tapered panel options to help you create the most effective design for your project — and get the performance and longevity you deserve out of your roof!
• Ideal for use over structural roof decks to divert water to drains
• Extended panel design uses up to approx. 30% less applied polyiso, which translates into up to approx. 30% less material handled and 30% less adhesive — resulting in less labor for you!*
• Available in glass fiber-reinforced cellulosic felt facer (Tapered & NH Tapered) and a coated glass facer (Ultra Tapered & NH Ultra Tapered)*Savings dependent on roof size/design and cost of material/labor.
