Spring, Texas -- Bayer MaterialScience llc has revised its International Code Council evaluation service report (ESR) 2072, which lets architects, contractors and building inspectors, know that a product meets all required life safety and building codes.
Bayer's revised ESR 2072 has five significant changes and eliminates the requirement for a separate ignition barrier and thermal barrier. ESR 2072 covers Bayer's residential spray polyurethane foam (SPF) insulation, Bayseal Closed-Cell insulation.
The changes are as follows:
The ESR now addresses all four formulations of Bayseal Closed Cell SPF insulation - Bayseal CC, Bayseal CC Polar, Bayseal CC X, and Bayseal CC XP, the company said in a 22 Aug news release.
Bayseal CC X and Bayseal CC XP may now be used in service-only attics and crawlspaces without the prescriptive ignition barrier or additional fire-retardant coating.
DC315 (manufactured by International Fireproof Technology Inc.) may now be used as a coating over all Bayseal Closed Cell SPF products. DC315 serves as an interior finish without the separate 15-minute thermal barrier.
Fireshell BMS-TC (manufactured by TPR2 Corporation) may now be used as a coating over all Bayseal Closed Cell SPF products. Fireshell BMS-TC serves as an interior finish without the 15-minute thermal barrier.
Each of the four formulations of Bayseal CC SPF insulation are now recognised as a water-resistive barrier without additional building wrap.
"Even though ESRs are not mandatory for product use, Bayer's position is that an ESR provides the assurance our customers need to know that they're in compliance with all applicable codes," said Jose Luna, technology manager, BMS spray insulation and roofing materials.
He added, "We're particularly pleased to get the reissued ESR 2072 into the hands of the builder community; the changes in ESR 2072 will help residential architects and builders to meet prescriptive code requirements with fewer products and lower installation costs."
