Spring, Texas The US construction industry uses the International Code Council Evaluation Service Report (ESR) to let architects, specifiers, contractors and building inspectors know that a product meets all required life safety and building codes.
Bayer MaterialScience llc has added new data to its ESR 1655 that outlines significant changes on thermal resistance values, fire-rated assemblies, prescriptive barriers, and code compliance. ESR 1655 covers Bayer's spray polyurethane foam (SPF) insulation, Bayseal Open-Cell (OC).
These changes cover DC315 (manufactured by International Fireproof Technology, Inc.) which may now be used as a coating over all Bayseal OC SPF products. DC315 serves as an interior finish without the separate 15-minute thermal barrier.
Fireshell BMS-TC (made by TPR2 Corp.) may now be used as a coating over all Bayseal OC SPF products. Fireshell BMS-TC serves as an interior finish without the 15-minute thermal barrier. Fireshell BMS-IC (manufactured by TPR2 Corporation) may now be used in attics and crawlspaces.
There is also more detail on National Fire Protection Agency (NFPA) 285 tested exterior wall assemblies using Bayseal Open Cell (OC) in Types I, II, III and IV construction, including updated R-values for insulation installed at thicknesses greater than 3.5 inches.
When required by the code, all SPF insulation must be used with the appropriate ignition or thermal barrier; the specific combination of SPF and fire-resistive coating is dependent upon the type of construction.
As the technical evaluation services subsidiary to the International Code Council, ICC-ES provides unbiased, third party building product technical evaluations.
"As with our recently reissued ESR 2072, ESR 1655 is a particularly good tool for the builder community," said Bayer spray insulation and roofing materials chemist Richard Romero, in a company statement. "We know builders and residential architects are challenged to keep up with code requirements.
"ESRs are a single-source resource to quickly find manufacturer usage requirements in response to applicable codes. Plus, the Bayseal OC SPF ESR has a table to easily find the R-value in all common installation thicknesses."
