About XTR Soffit
dasso.XTR® is a strand-woven bamboo composite compressed under high heat and pressure to reach a density above 1150 kg/m³
Delivered with concealed suspension system and matching perimeter trims.

Microscope views of dasso XTR® bamboo cells: before the thermo treatment the cells are still filled with sugars and starches, the food source for mould and fungi. After thermal treatment those nutrients are decomposed, leaving no breeding ground for decay.
