Wood is a natural insulator
Wood has a lower thermal conductivity compared to concrete, steel-frame and masonry construction and is ideally suited to energy-efficient design. As a natural insulator, it provides some of the world’s coldest climates with warm and comfortable dwellings.
Advantages and benefits of wood construction
Wood is valued for its beauty, strength, flexibility and practicality. It can be cut, carved, planed, milled, bent, joined, glued, nailed, bolted, laminated, spliced and weathered. It can be a load-bearing structure, a finish material or an exterior cladding. As a building material, wood is easily adapted, reused or recycled. It is well suited to additions and retrofits, and wood systems can be dismantled with relative ease and used elsewhere. Wood construction has long been used for energy-efficient design and provides some of the world’s most affordable and comfortable housing. Wood is used in the vast majority of single-family homes in Canada and many multi-family projects.
Experienced wood contractors are widely available, and workers of varying skill levels can quickly learn wood construction techniques. Wood construction can be done on site, allowing for quick solutions when changes are required.
Wood is used in many types of buildings, from single-storey homes to condominiums, multi-storey offices, schools, industrial facilities, recreational centres and arenas. And as we grapple with an ever-growing need for affordable housing, wood is delivering economical, comfortable and safe solutions.

Wood is well-suited to affordable, prefabricated and low-carbon construction
Wood can be a compelling alternative to other more carbon-intensive materials, offering distinctive value and savings. It is well suited to rapid all-season prefabricated construction that is quieter, cleaner, lighter to transport and saves time. As cities continue to grow exponentially, this means less noise and disruption in dense urban settings. Modular wood building systems can be easily put together akin to life-sized Lego.
They can be assembled by fewer workers in tight more difficult-to-reach construction sites. Precisely manufactured assemblies, such as prefabricated light-frame walls and mass timber panels, provide thermal benefits and can help make building envelopes more energy-efficient and airtight. Wood buildings are well suited to energy-efficient construction and the rigorous standards of Passive House and net-zero-ready design. Whether made of light-frame wood systems, panelized products or factory-built assemblies, wood construction is economical and expedient. This is increasingly supported by benchmarked studies (PDF) and reports (external link).
Wood can often be locally sourced and manufactured. Wood’s smaller environmental footprint means it can meet the anticipated regulatory requirements for buildings to achieve carbon targets. This combined with its lighter weight can reduce greenhouse gas (GHG) emitted during transportation to construction sites. Along with environmental benefits, this reduction in weight lessens the need for more costly foundation work and in some cases, in poor soil conditions, timber buildings can be built taller than steel and concrete.

Wood delivers benefits beyond cost and design efficiencies
When considered over its lifetime—from the harvest of raw materials through manufacturing, transportation, construction, disposal or recycling—wood has less embodied energy, reduces air and water pollution and has a smaller carbon footprint. Wood can help maximize a building’s energy efficiency. Its low thermal conductivity compared to steel and concrete makes it well suited to high-performance Passive House and net-zero ready design. It is part of B.C.’s climate solution.
Beyond environmental benefits, building with local wood products boosts communities, jobs and the economy. For example, through a collaboration of the local, regional, and Gitxsan governments, the community of Upper Skeena realized their vision of a new multifunctional recreation centre built with wood. Beyond offering a cost-effective solution, the all-wood facility brought value to the community in the form of jobs, culture, social support and community pride.
