Fire on £20M Engineered Timber Building Brings Wood-first Policy into Question

Thu, 2 Oct 2014

According to NZ Wood , when it comes to fire in engineered timber buildings, large sized timber members, whether sawn timber or glulam, have the inherent ability to provide fire resistance because of the unique charring properties of wood; moreover, even though wood does burn, it is claimed that the contribution from the timber building materials to the fire load is usually small compared with the contribution of the building contents which constitute the main source of fuel. Whilst these statements probably are attributed to laboratory tests, this month’s fire on the £20 M GlaxoSmithKline (GSK) Carbon Neutral Laboratory building for Sustainable Chemistry at the University of Nottingham in the UK brings into question these statements...
