INSULATION AND FIRE RESISTANCE
Each CLT panel consists of several massive planks of wood glued together, therefore, it already offers decent thermal insulation and soundproofing properties. However, to achieve better results in these parameters, it' recommended to add a layer of insulation. Besides, as already mentioned, insulation can be attached to the panel during the manufacturing process, therefore it won't require any effort on the construction site. Meanwhile, when it comes to fire safety, CLT is one of the best materials available on the market, as in the event of a fire it will slowly char, instead of burning with an open flame. Just make sure that you use appropriate cladding materials that won't compromise these properties by igniting the fire.
