Metacaulk® On-site Testing

In 1995, an on-site fire test laboratory was built for the purpose of conducting UL witnessed burns for through-penetration and construction joint assemblies. Our laboratory has been designated by UL under their Witness Test Data Program for fire testing to UL 1479 & UL 2079.

Firestop Metacaulk
A computerized control room monitors all phases of test burns as specified by ASTM E-814 (UL 1479) or ASTM E-1966 (UL 2079).
Firestop Metacaulk
Two on-site test ovens allow for quicker response to customer needs for UL approved systems and speed the development of new systems.
Firestop Metacaulk
After test burns, assemblies are immediately subjected to a hose stream test to complete the ASTM E-814 (UL 1479) or ASTM E-1966 (UL 2079) procedure.
