You Save Money

Energy savings of 20% – 50% can be achieved by using spray foam insulation. We will create a thermal envelope around your home or business. In addition to controlling temperature, spray foam insulation acts as an air and moisture barrier which windproofs and seals wall, floor and ceiling cavities to prevent air movement. Unconditioned air cannot seep in from outside bringing with it spores, pollen, noise, and other environmental pollutants which are transported through traditional insulations. The occupant is able to truly control his indoor air quality. 

Environmentally Friendly


Green Advantage uses the highest quality spray foam insulation products in the marketplace. The foam we use is water blown and has zero global warming potential. There is no HCFC-245a blowing agent to off-gas from the foam during or after installation. Many of our competitors use "245a foams" which are potentially harmful to the environment and your indoor air quality. In addition, our foam is VOC Free. The U.S. Green Building Council endorses products that do not contain Volatile Organic Compounds. By using environmentally conscious spray foam insulation, you are doing your part to conserve natural resources for future generations.
