by Brianna Crandall — May 24, 2019 — Johns Manville, a Berkshire Hathaway company and building products manufacturer, recently announced the release of its 800 Series Spin-Glas Ultra, a rigid fiberglass insulation board with a new polypropylene-coated (poly-top) facing that allows it to be wiped down for better cleanability.
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.
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. Bonin stated:
We regularly host events where we can get feedback from the contractors who install our products. 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. Westerdale pointed out:
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.
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 is now available from Defiance, Ohio. For more information about 800 Series Spin-Glas Ultra, download the data sheet or the FAQs from the Johns Manville website. The company has operated since 1858, now on three continents.
