Unlike other building materials, wood is a renewable resource that grows naturally, right here in Quebec’s forests. It also has a lower environmental impact than other materials in terms of energy, climate change and air pollution.


Solid wood panels are as strong as concrete but five times lighter—they are even 15 times lighter than steel—, meaning less weight on the foundation and ground supporting the building.

Thermal insulation and resistance to fire

Wood is more resistant to heat loss than other materials: seven times more than concrete and 500 times more than steel. It therefore takes less energy to heat and cool buildings built of wood. CLT solid wood panels also deliver good acoustic performance that complies with the existing standards.


Using CLT solid wood in a building increases its fire resistance and lowers the propagation risk, as heat has very little impact on the strength of wood.

Efficient construction

Prefabricated panels cut to the required dimensions are delivered to the site, and the openings for doors and windows are cut to an accuracy of one tenth of a millimeter using computer numerical control (CNC) precision machinery. Everything is planned and organized so the building can be erected quickly.

The carbon story here is a really good one. If we built a 20-story building out of cement and concrete, just manufacturing that cement would produce 1,200 tonnes of carbon dioxide. If we built it with wood, we'd sequester about 3,100 tonnes, for a net difference of 4,300 tonnes between the two scenarios. That's the equivalent of about 900 cars removed from the road in one year.

Health and aesthetics

Did you know that the presence of wood indoors promotes better health for a building’s occupants? In addition to knowing that they live in a home built with a renewable material, urbanites can now comfortably enjoy wood’s pleasant surface temperature and its ability to temper sudden changes in temperature and humidity. Not to mention the character that the majestic wood posts and beams add to the interior of their condominiums.

Small environmental footprint

In addition to providing long-term carbon storage, CLT solid wood panels consume less energy, both during the manufacturing process and when used at the construction site.


Nordic Wood Structures, who makes the CLT solid wood panels used in Sotramont’s construction projects, is FSC-certified by the Forest Stewardship Council. The Chibougamau-based company manages the boreal forest sustainably, together with the Cree Nation.

Acoustic efficiency

The project was designed and monitored by a professional in acoustics to ensure compliance with standards. Buildings made of solid wood must be insulated with care to ensure their soundproofing for the comfort of their occupants. For example, the wood must be protected from rain and moisture.
