CLT wood, why?
April 28, 2022
Halzebatz has designed its solutions around the use of CLT wood. What are the advantages ?
Cross-laminated timber (CLT) is a wood-based construction material, which comes in the form of a multi-layered panel consisting of 3 to 11 layers of lamellas or slats of wood glued together. Each layer contains lamellae arranged in a single direction.
The solid wood structure used in our modules ensures good thermal inertia , while the CLT panels ensure the bracing: the stability of the structure.
CLT can do without a general vapor barrier and offers little to no risk of air “leakage”.
It can also be used as an interior finish , thanks to its rigidity, and offers a low floor/roof thickness .
What are the differences with a wooden frame?
The alternation of the wooden frame and flexible insulation causes for its part a low thermal inertia and the need to add additional bracing.
In a wooden frame, the general vapor barrier is mandatory and involves many risks of “leakage” of air.
Finally, the wooden frame means that interior finishes must be provided and offers a floor/roof thickness that is clearly greater than the CLT for an equivalent span.
