Cross Laminated Timber (CLT) is a timber product commonly used for pre-fabricated structural applications. The main benefit of CLT is the reality it’s bringing to structures construction using wood. It is widely considered as the engineered wood of our time and the future.
The benefits this offers new buildings is amazing – timber panels are much lighter than concrete, much more effortlessly worked and less tedious to erect. Nonetheless, there are other benefits offered by CLT to building construction. This article will give a brief overview about some of them.
1. Stability and Strength
CLT panels form a sturdy, structurally strong building system which outperforms concrete structures and offers top-notch dimensional stability. It likewise provides substantial overall shear strength performance at a stunning weight to strength ratio when compared to other typical structural materials.
2. Seismic Strength
CLT panels provide a unique and strong horizontal load resisting system due to their dimensional stability and rigidity. Experts have actually done considerable seismic testing on CLT and have discovered that they perform wonderfully without any residual deformation, especially in multi-story applications. The experts tested a seven-story building in Japan and discovered that the building suffered virtually no damage after suffering fourteen consecutive seismic events.
Research outcomes revealed that the acoustics performance of a building is contributed to by the mass of the wall. Building systems of CLT provide awesome sound control for impact and airborne sound transmission. Some membranes of the timber and the use of sealants ensure that the building structure is airtight and sound insulation of the surface of walls and floors is improved.
4. Thermal Performance
The U-value or rather coefficient of heat transfer determines the thermal performance of CLT. Thicker CLT panels have lower U-value and hence, require virtually no insulation because they better insulators. Due to the fact that CLT panels are solid, air infiltration to the building envelope is nearly zero. This is why interior temperatures of a finished CLT construction can be maintained with only one-third of a typical cooling or warming energy.
5. Fire Resistance
The thick cross-section of CLT offers essential and exceptional fire resistance. Because of its mass, CLT panels char slowly. When charred, burning slows down and eventually stops because the source of air is taken away. Also, CLT assemblies have a lot fewer concealed spaces which, therefore, decrease the probability of fire circulating undetected.
All explained properties above are what were put into consideration when Qijik when we develop our CLT solutions with pannaq OHT ® wood . Our pannaq OHT ® wood with CLT is engineered in such a way that you can use them for any residential, commercial, or industrial structure with the guarantee that they are strong enough to last long, resist tough weather conditions and decay.
