ACFoam®-HS CoverBoard

ACFoam-HS Coverboard

  • 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.
