Closed-cell polyisocyanurate (polyiso) foam core integrally bonded to heavy weight high performance ACFoam®-IV inorganic coated glass facers. Manufactured in accordance with ASTM C1289, Type II, Class 4, Grade 1 (80 psi (551 kPa) minimum, up to 110 (758 kPa) compressive strength).
Available in 0.5” thick 4ft x 8ft (1220mm x 2440mm) and 0.5” thick 4ft x 4ft (1220mm x 1220mm) panels.
Provides an R-value of 2.5 as determined by ASTM test method C518 at 75°F mean temperature.
Manufactured using CFC-, HCFC- and HFC-free foam blowing technology with zero ozone depletion potential (ODP) and virtually no (negligible) global warming potential (GWP).
Contains 2.5% recycled materials by weight (Atlas Technical Bulletin: TB-2).
Recognized by the GREENGUARD Environmental Institute as resistant or highly resistant to mold growth based on independent testing using GREENGUARD Test Method GGTM.P040 (ASTM D6329) for microbial resistance.
Typically specified for use in new and re-roofing applications. ACFoam®-HS CoverBoard is used in built-up (BUR), modified bitumen, mechanically attached single-ply and adhered single-ply roofing systems. These roofing systems depend on proper installation for successful performance. Refer to FM Approvals® RoofNav and UL Online Certifications Directory for additional application details.
Field testing has confirmed significantly more efficient use of solvent-based adhesives than with organic faced insulations.
