The insulation is designed with a facing that provides a similar aesthetic to Johns Manville’s Micro-Lok® HP Ultra pipe insulation, which also features a polypropylene coated facer. This polypropylene coating allows both 800 Series Spin-Glas Ultra and Micro-Lok HP Ultra to be wiped down for better cleanability.

Lance Bonin, Johns Manville’s Mechanical Portfolio Manager, said the idea for this new facing began at one of Johns Manville’s Contractor Advisory Councils.

“We regularly host events where we can get feedback from the contractors who install our products,” Bonin said. “Over the last year, one thing we heard repeatedly was that contractors want a poly-top facing for our Spin-Glas board insulation that is similar to the poly-top facing we use on our Micro-Lok® HP Ultra pipe insulation.”

The new facer is a scrim-reinforced, polypropylene-coated, metalized polyester.

Meredith Westerdale, Johns Manville’s Mechanical Product Manager, explained that this new facing is unique from other mechanical insulation facings. “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. 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.

800 Series Spin-Glas Ultra will be available from Defiance, Ohio, in late April. For more information about 800 Series Spin-Glas Ultra, download the data sheet or the FAQs.
