This revolutionary material not only allows the creation of environmentally friendly and energy-efficient buildings but also significantly reduces construction time, which is a priority in today's dynamic reality of the construction industry.
Cross Laminated Timber or CLT panels - massive building material made of wood. Due to its excellent physical and mechanical properties, it has excellent thermal insulation properties and withstands heavy loads. The vertical lamellas of the slab determine the bearing capacity, while the horizontal lamellas determine the longitudinal stiffness. The adhesive seam between the lamellas is formed at the molecular level and is absolutely harmless, due to these factors it is widely used in Europe.

Cross Laminated Timber or CLT, is an engineered product from wood, similar in construction to an extremely durable plywood, used for fabricated structural applications. From residential dwellings to apartment buildings CLT technology allows for a durable construction made from wood.
Layers of timber, known as lamellas, are glued together with the grain alternating at 90 degree angles for each layer. The exterior layers’ grains run lengthways, giving optimum strength. CLT is manufactured in a similar way to glulam, except that glulam is layered with the grain. Cross-laminating layers of wood veneer improves the structural properties of wood by distributing the along-the-grain strength of wood in both directions, and this means that CLT panels can be used to form complete floors, walls and roofs.
While CLT is a timber product, it should not be thought of as a timber frame product – it is a timber panel product that actually has similar characteristics to that of a pre-cast concrete panel. The advantages this offers new buildings is quite exciting – timber panels are much lighter than concrete, more easily worked and easier to erect.
Oxley Trade sources CLT panels from Europe, from manufacturers who go through a rigorous quality selection process and comply with all relevant laws and regulations. All wood is FSC and PEFC certified. Get in touch today, to find out how you can use this innovative building material in your next project!
