Wood is the construction material of the future as growing social awareness of resource conservation and simultaneous technical developments are bringing mankind’s oldest building material back into the spotlight. Through the intensified use of wood, “new forests” are emerging in our cities and towns, providing a substantial store of carbon which eases the burden on the environment. Building with CLT makes an important contribution to protecting the climate and the environment.
Widely available everywhere, wood is a natural and sustainable raw material which grows back faster than it is used up. During its growth, a tree absorbs carbon dioxide from the atmosphere and a building constructed with wood stores carbon for centuries. At the same time, with the help of solar energy and photosynthesis, new trees grow back and absorb more carbon. 1 m³ of wood stores approx. one ton of CO2, thus the use of wood plays an active role in reducing the greenhouse effect. A timber house which is disassembled after centuries of use does not leave behind worthless rubbish, but rather utilisable wood. Individual elements can be reused, while scrap wood can be used as a source of energy. CLT by Stora Enso is made from PEFC-certified softwood derived from sustainably managed forests and controlled sources. A PEFC certificate guarantees that CLT is produced according to the highest environmental and ethical standards.
CLT is a solid wood construction product consisting of at least three bonded single-layer panels arranged at right angles to each other. From five layers, CLT can also include middle layers (transverse layers) without narrow side bonding. CLT panels are made of spruce or pinewood, consist of several layers and are available in different panel thicknesses depending on structural requirements. The layers are bonded using environmentally-friendly adhesives. CLT is an approved and tested construction product and its production process is subject to strict external tests that ensure high-quality and safe construction with CLT. Diligent production planning ensures that the raw materials for producing CLT are used in the most efficient way. With correct planning, construction and protection against adverse weather conditions and damp, CLT buildings can last for centuries.
