A Buffalo laboratory with sixty years of operation behind it, running full-scale fire testing alongside acoustic, structural and building envelope work, and testing materials and assemblies to ASTM, UL and NFPA standards at both large and small scale. Accredited by NVLAP (lab code 200291-0) and by the International Accreditation Service as a testing laboratory (TL-216) to ISO/IEC 17025, with state approvals in New York, California, Ohio and Florida. It is owned within the National Gypsum group and sells testing to external clients — worth knowing when weighing a report on a gypsum-based assembly, which is why it is stated here rather than left out.
