Spring, Texas - Why use two products when one will do the job? asks Bayer MaterialScience llc. The group has revised its International Code Council Evaluation Service Report (ESR) 2072 for SPF insulation, and eliminated the need for a separate ignition and thermal barrier.
An ESR lets architects, specifiers, contractors and most importantly, building inspectors, know that a product meets all required life safety and building codes, BMS points out.
Bayer's revised ESR 2072 has five significant changes. ESR 2072 covers Bayer's residential spray polyurethane foam (SPF) insulation, Bayseal Closed-Cell (CC) insulation.
Changes to the reissued ESR 2072 are:
* The ESR now addresses all four formulations of Bayseal Closed Cell (CC) SPF insulation.
* The CC X and CC XP types 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 Corp.) may now be used as a coating over all BMS closed cell SPF products. Fireshell BMS-TC serves as an interior finish without the 15-minute thermal barrier.
* Each of the four formulations 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, Bayer MaterialScience llc Spray Insulation and Roofing Materials, in a company statement.
"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."
