Benefits

• Improved fire resistance — achieves a Class A rating over combustible decks without the use of a gypsum board or fire-rated slip sheet. When used with single-ply TPO, a total of at least 3" (76 mm) of EnergyGuard™ Ultra Polyiso Insulation is required; a Class B fire rating is also obtained when using at least a single layer of 1.5" (38.1 mm) EnergyGuard™ Ultra Polyiso Insulation.
• Meets the requirements of ASTM D3273 for resistance to growth of mold.
• EnergyGuard™ Ultra Polyiso Insulation is designed for use in practically any low-slope roof application, including built-up roofs, modified bitumen, or most single-ply roofing systems.
• Offers an alternative to a paper facer; coated glass-fiber facer reduces adhesive absorption and helps to improve nail pull strength.
• Provides the highest R-value per inch compared to non-polyiso types of insulation of equivalent thickness.
• Because of its light weight, this material is easy to handle on the job site and installs faster.
• Easier cutting in the field provides the installer with simplified fabricating on the roof deck.
• Available in thicknesses ranging from 0.5" to 4.6" (12.7 mm to 116 mm).
