CLT (Cross laminated Timber) is a wood element that typically consists of 3, 5, or 7 lamstock layers. The layers are laminated at a 90 degree angle and pressed to a complete structural element. Due to the cross lamination, the complete structural element has a dimensional stability, great strength, and rigidness.CLT can be structural elements up to 20 meters long or complete sectional elements that can be used as walls, ceilings, and floors.
CLT stands for cross laminated timber and it is a mass timber product that typically consists of 3, 5 or 7 layers of lumber boards that are stacked, glued, and pressed at a 90-degree angle on each other. This cross lamination creates a very rigid element. In addition to this CLT, elements are very dimensionally stable.
CLT is a relatively new laminated wood product but it has quickly become a very popular element in different constructions because it has a lot of advantages.
· CLT-elements weigh less than steel and concrete.
· A building with laminated wood elements typically weighs less which means that the foundation can be smaller.
· Less concrete is used which is good for the environment.
· A smaller crane can be used to lift the CLT elements into place due to the lower weight of the elements.
Every CLT element is specially made for the function it is going to fulfill in the building. In the production phase, our machines can omit laying wood where the door and window openings will be. This means that less tree is wasted and that the CLT elements are ready to leave for the construction site as soon as they leave the press line. The production can be optimized for a just-in-time production which makes the need for construction site storage unnecessary. The production can also be organized so the CLT elements arrive at the construction site in the order they are needed in the building. All this contributes to a very efficient and quick project completion which also reduce the costs.
Another good reason for building with CLT elements has to do with the natural qualities of wood. From natures hand wood has good insulating properties – including sound and warmth.
Buildings made with CLT elements also perform well in earthquakes. A CLT building does not suffer as much damage as a concrete and steel building.
CLT also performs well in case of fire. CLT is a mass timber product that does not burn through, but chars on the surface at a predictable rate. The structural integrity of the building is also maintained over a long period in case of fire.
