For information about the fire performance of timber, including LVL and glulam, click on this link https://www.woodsolutions.com.au/articles/design-fire. Note particularly the advice that Fire tests have shown that glulam or LVL members can be regarded as solid timber for the application of AS 1720.4. The glue is not considered to affect the fire performance of these engineered products. Therefore the same Group Number will apply for glulam as for solid timber of the same species (Group 3 for all species tested so far).Glulam in fire
