More about air quality

Volatile Organic Compounds (VOCs) are present in many building products such as treated wood products, insulation, adhesives, carpeting and some paints. They can even be found in hairspray, Deodorants and Air fresheners. They can cause dizziness, headaches, eye irritation and Asthmatic reactions (New Zealand has the second highest Asthma rates in the world). At high concentrations, they can even be toxic.

VOC chemicals evaporate into the air and are dispersed throughout the life time of the product, a process known as off-gassing. Some products like spray foam insulation will cure quickly, and within a few days the VOCs are virtually gone or are at non-detectable levels. Other products, like pressed wood cabinets, will off-gas for many months. And, if the material is exposed to high temperatures or high moisture levels, emissions will be even higher.

But you have options; such as Glass, ceramics, metal, stone and other hard and inert materials don’t release any VOCs. Solid wood is better than composite. Tile and hardwood are a better choice than vinyl flooring. Natural carpet like wool is better than synthetic. Water-based products, such as latex paint and caulking, have lower levels of VOCs than solvent-based products.

Points to note

Buyer Beware when buying products and materials that say they are “low VOC”. There are no standards for using the term; it can mean one thing to one manufacturer and something different to another. Your best option is to buy products that have been tested and certified to emit low levels of VOCs.

One standard to look for is the Green Seal (GS). This tells you a product has been rigorously evaluated and tested and meets certain international environmental standards. A list of Products can be found on the Environmental choice New Zealand website.
