Cork flooring: Eco-friendly alternative

What: Cork is the outer bark of a tree, Quercus suber, which is grown primarily in the Mediterranean region.

Application: Installing cork flooring is an environmentally responsible alternative to wood for a number of reasons. Cork is durable, strong and requires little maintenance.

Despite having to be shipped from the Mediterranean, with the associated energy costs, cork is considered resource efficient because it limits pressure on forest products and the environmental services they provide. It is also preferable because it lasts so long, and avoids the need to replace less durable products.

Cork is environmentally responsible because the bark is carefully harvested to preserve the tree and to ensure its productivity year after year.

Benefits: Cork is naturally moisture, mold and rot-resistant. It even absorbs sound.

These aspects promote good indoor air quality by limiting the number of items in a house that can harbor molds and other forms or fungal growth.

Challenges: Cork can cost more than conventional flooring. Care is required during installation to provide adequate cure time. Any adhesives used should be low-VOC (volatile organic compounds).
