The superior fire performance of timbers can be attributed to the charring effect of wood. As wood members are exposed to fire and the wood begins to burn, a char layer is formed. The char layer acts as an insulator and protects the core of the wood sect...
The Fire Test Laboratory of NGC Testing Services (NGCTS) conducted testing for American Wood Council (AWC) on a load-bearing, Cross-Laminated Timber (CLT) and gypsum board wall assembly to evaluate its fire resistance properties when exposed to fire acco...
Fire Resistance Performance Evaluation of a Penetration Firestop System Tested in Accordance with ASTM E814-13A: Standard Test Method for Fire Tests of Penetration
The objective of the test described in this report was to evaluate the ability of multiple through-penetrations to provide a fire barrier. This test also evaluated the ability of the through-penetrations to maintain their structural integrity when subjec...
The objective of the two tests described in this report was to evaluate the performance of cross-laminated timber (CLT) and nail laminated timber (NLT) construction protected with two layers of %-in. (16-mm) type X gypsum board when exposed to the therma...
