Lucideon has released a new testing guide for manufacturers of cross-laminated timber (CLT) in offsite buildings

CLT is an engineered timber product made from bonding layers of sawn timbers together. This provides a sustainable and tough panel which is ideal for use in offsite construction and is becoming more popular as a building material for the whole construction industry. The treated engineered wood can be used in walls, floors and roofs to construct the full building envelope.

Design using cross-laminated timber panels falls within the timber code EC 5 but is often considered by many to fall between timber and masonry design; panels act as solid planes and there is no need for an infill. Design by standard will often give a much more conventional answer than design by testing.

The testing within the guide includes thermal performance, durability, acoustic and airtightness, and water tightness of connections, and can be executed to establish load span characteristics of floors and roofs and to ascertain the maximum span and load characteristics of walling panels.

Author of the guide, Joanne Booth, business manager – construction at Lucideon, said: “This is the third guide in a series we’re creating for offsite and modular building product manufacturers.

“The guide is designed to help manufacturers launch new products into the market by detailing test requirements to understand the structural integrity and physical performance of both panels and the full composite system.”
