Once you have created a tight building envelope the need to examine indoor air quality is essential. Many builders are using spray foam insulation to reduce air infiltration but do little or nothing to address indoor air quality. With the use of spray foam in your exterior walls and rafters the air is trapped inside the home. This is good for maintaining air temperature but not for air quality.
One of the steps we implement is installing an Energy Recovery Ventilator (ERV) that allows us to change the air in our homes 2 – 3 times a day. The ERV brings in fresh air and has the ability to reduce molds, dust and allergens.
We are very concerned with the products used inside our homes. All of the paint has no VOC’s (Volatile Organic Compounds). Our cabinets are built with wood that has no Urea Formaldehyde and are finished with Low or no VOC stains and finishes. Flooring is also of great concern, we use an organic concrete dye that is not an acid stain to eliminate off gassing or wood flooring with no formaldehyde or toxic finishes.
