Johns Manville has developed a glass fiber insulation board with a polypropylene (PP) coated (poly-top) facing. Johns Manville has developed 800 Series Spin-Glas Ultra, a glass fiber insulation board with a polypropylene (PP) coated (poly-top) facing.
According to the company, the PP coating allows the board to be wiped down for better cleanability.
‘Most facings used on mechanical insulation have a kraft paper component, but the new facing we are using on our 800 Series Spin-Glas Ultra board has no paper,’ said Meredith Westerdale, Johns Manville’s mechanical product manager. ‘We’ve found that for fiberglass boards, this can improve their wrinkle-resistance,’ she said.
800 Series Spin-Glas Ultra can be used on any ASJ specification as it meets the requirements of a polymeric film type ASJ per the NIA Glossary. Additionally, it meets the highest rating for low permeance vapor retarders as a Type I classified material per ASTM 1136.
