Green Flooring Options

When it’s time to replace flooring, think outside the big box stores. Sustainable flooring is both durable and beautiful.

Cork



Cork is made from the peeled bark of Cork Oak trees, which can be sustainably harvested every nine years without harming the tree. It is naturally resistant to fire, insects, and microbes. Cork is available in snap-together floating floor systems or adhered tile. Showercork is made from ¼” slices of wine cork adhered to a paper backing. It’s designed to be grouted in place and then coated with urethane finish, so it’s especially appropriate for wet areas. Cork flooring is foot-friendly, sound-dampening, and durable.

Earthen Floors



Earthen flooring is earth mixed with fibers, compacted by hand and trowel, and then coated with a natural sealant like hemp or linseed oil. Very high traffic areas may require a flagstone inset. Earthen floors are durable, easily repaired, and kind to feet. Because they are made primarily with materials straight from the building site, their resource impact is near zero. Earthen floors are most often installed over a bed of gravel, but they can be even be layered on top of pre-existing flooring such as concrete or wood, as long as the structure can support the weight of the earth. Because of their high thermal mass, they are ideal for the passive solar home.

Linoleum

A linoleum floor will last 30-40 years, compared to 10-20 years for vinyl flooring. At the end of its lifespan, it is fully biodegradable. Marmoleum, the most popular brand of linoleum, is made of linseed oil from flaxseeds, rosin from pine trees, wood and cork flours, limestone, metal-free pigments, and jute, in a waste-free process. Natural linoleum is available in a rainbow of colors in sheet, tile, or click-style flooring.

Local, Sustainably Harvested or Reclaimed Wood
LemRusticHemlockWant a wood floor? First check with local green builders, who may know locals harvesting their wood sustainably. A local builder may also know sources of reclaimed materials close to home. If you’re looking for a rustic look, try aged wood from barns. Reclaimed wood tells a story, whether it’s maple from a factory floor or flooring from an old bowling alley. Very often, the same dealers who sell reclaimed wood also sell sustainably harvested wood. Forest Stewardship Council certification gives you a starting point for learning about how wood is harvested, although there is the predictable controversy about whether or not their standards are stringent enough.

Woven Bamboo Flooring

Bamboo




Bamboo’s advantage over wood is its fast renewability. It is a grass ready for harvest within three to six years that regenerates without replanting and requires little chemical input. However, due to the recent popularity of bamboo,


corporations are clearing forests in China to plant it. Monocrops of bamboo decrease biodiversity and increase erosion in these clearcut areas. The more industrial bamboo farming becomes, the more chemicals are used to manage the crops. The lesson here is that not all bamboo is created equal. Look for companies like Teragren, who explicitly detail their commitment to sustainability.
