Green Flooring Materials
Many kinds of flooring materials can be considered green, including:
There are basically two types of wood: softwoods, which come from rapidly growing trees like pine and fir, and hardwoods, such as oak, maple, teak, etc. Be sure all wood is FSC certified and does not come from old-growth trees. Even better, use reclaimed/recycled wood. Wood flooring is easy to clean with simple products like vinegar and water. Only use zero- to low-VOC and plant-based sealants.
There are more than a thousand different species of this fast-growing woody grass. It is stronger than most hardwoods, and, like wood, can be sanded and refinished multiple times. (Luckily, the type used for flooring is not the kind pandas feed on.) After harvesting, it quickly regenerates. TIP: Even if it comes factory-finished, experts recommend resealing it to protect it from doggy water-bowl spills.
Made from linseed oil, a byproduct of flax (Oleum Lini). It is antibacterial, making it ideal in kitchens and bathrooms. It is also antistatic, so it repels dust and dirt. It comes in a wide range of colors, and even though it does offgas due to the oxidation of lineolic acid, it is less harmful than vinyl, and is considered to be more environmentally friendly.
From the outer bark of the cork oak tree (Quercus suber). The bark naturally sheds and regrows about once a decade, so harvesting does not harm the tree. Cork resists rot and mold and makes a great sound-absorber and insulator. It also adds an extra cushioning and “bounce” to the step, great for the long-standing cook and indoor ball-tossing!
Other good flooring materials to consider are concrete, brick, tile (ceramic, porcelain and glass), terrazzo and stone.
Even though its low cost and wide variety of colors and patterns make it a popular flooring choice, polyvinyl chloride (PVC) continues to be the subject of considerable controversy. Its production releases an extraordinarily toxic chemical–dioxin–and many, including the Healthy Building Network, consider PVC to be one of the “most environmentally hazardous consumer materials produced.”
Does Green Building Cost More?
It doesn’t have to. Many green building features and products cost the same as, or even less than, their conventional counterparts. Other green features may cost more upfront but result in savings year after year. Energy-efficiency upgrades, for example, usually pay for themselves by lowering your monthly energy bill.
