Cross-laminated timber panels are large, rigid, solid timber construction sheets used for all elements of a building’s superstructure – walls, floors and roofs.
They are made from kiln-dried, finger-jointed timber planks (typically spruce), cut into sheets and bonded under pressure in perpendicular layersCLT is an ideal material for off-site construction, with panels arriving on site machined to precise sizes, including apertures and trunking conduits
Timber products that have been engineered to remove natural weaknesses and enhance natural strengths. They provide stronger, longer, wider and more stable solutions than natural timber.
They deliver sustainable, low carbon structural solutions with a unique elegance, low weight and natural beauty.
Engineered Wood Products include:
Cross-laminated timber (CLT) is a solid-wood construction panel made from at least three layers of lamella (pine or spruce) glued crosswise. The normal size is 3 x 16 metres, but panels are also available in a range of dimensions and grades. The CLT panels have pre-cut openings for doors and windows, according to customer requirements. CLT is suitable for both interior and exterior walls, as well as ceilings and flooring.
The product has attracted a great deal of interest. Major CLT-based building projects have both been completed and are ongoing all over the world with the aim of developing the market and demonstrating the competitiveness of the technique compared with concrete. As a product, CLT has experienced double-digit growth since it was introduced in early 2000 and this trend is expected to continue in the years to come.
Timber is the most sustainable mainstream building product. It is naturally renewable. Over 90% of timber used in UK construction comes from Europe, where more trees are grown than harvested (source: TTF Statistical Review 2016).
Softwood and temperate hardwood forests in Scandinavia, Europe, Canada and North America are stable or growing. Growing forests act as carbon sinks; wood products act as carbon stores.
Ask for PEFC or FSC Chain of Custody certification.
