Construction at Le 8 Duplessis is advancing! In February, the walls and floors of the 3rd and 4th levels have been installed. Once fully completed, the structure will incorporate over 2,000 TRIFORCE® open joists, covering 30,500 linear feet or about 10km if they were installed end-to-end!
As for the walls, the prefab type preferred for this project are from our Multi-Residential Energetic Performance line. This means their R-Value, used as a measure of a material’s isolation efficiency, stands at 27.3. These walls are made of an air barrier, expanded polystyrene, OSB, R20 wool insulation, and a 0.15mm clear vapor barrier.
