Insulation Systems and Vapor Retarders

Insulation Systems and Vapor Retarders – August 2020

Insulation systems and vapor retarders featured in Metal Construction News’ August 2020 issue.

Bay Insulation Systems Inc.

Bay Insulation Systems faced metal building insulation is comprised of a resilient, light density, fiberglass blanket (NAIMA 202-96 insulation only) laminated to a vapor retarder facing. Faced fiberglass can be installed as a single layer or combined with un-faced metal building insulation fiberglass and support hardware to create a high R-value system. It is Home Innovations Lab certified to meet R-value, noted on the label, and has UL on the label to certify it meets Fire Class Rating A for interior use.

CertainTeed Corp.

CertainTeed’s MemBrain vapor retarder is a polyamide film that changes permeability with ambient humidity conditions. It reacts to relative humidity by altering pore size, allowing water vapor to pass through it. When relative humidity goes above 60 percent, pores in the material expand and permeability increases, permitting drying to occur in either direction, through vapor diffusion.

Covertech Fabricating Inc.

Covertech’s rFOIL Reflective Insulation 2200 Series is a single or double layer of polyethylene bubbles bonded to and sandwiched between a radiant barrier metalized foil and white polyethylene sheet. It can be taped to purlins, stapled to rafters or studs, or rolled out onto roof decking or existing shingles prior to installation of metal roofing or siding panels.

Huntsman International LLC

Huntsman International’s Icynene ProSeal hydrofluoro-olefin (HFO) is a high-density, closed-cell spray polyurethane foam insulation. Its HFO blowing agent is Honeywell’s Solstice, which has a lower global warming potential (GWP) than hydrofluorocarbon (HFC) blowing agents. Icynene ProSeal HFO includes formulations suitable for use in all climate zones and temperatures.

Silvercote LLC

Silvercote’s Energy Saver FP (fall protection) is made of glass mineral wool insulation and welded fabric panels. Bright fabric panels are welded to exceed ASTMD-751 and sized to minimize field modifications. The fabric panels are installed to roof interiors with a network of banding straps. There is an outer perforated foil laminated layer that reflects heat gain in the wall double layer system. Energy Saver FP provides OSHA-compliant fall protection at leading edges.

Therm-All Inc.

Therm-All’s R-Seal rigid insulation system for metal building roofs and walls provides a one-step insulation and air barrier installation. The rigid polyurethane board has high compressive strength and a durable finish. R-Seal rigid insulation board is available in tongue-and-groove and has integral tape tabs.
