    1.Outstanding Attic Insulation

    Brian 11/5/2012

    We had our attic insulated up to recommended standards and GNI were just amazing with the product and service! Our heating bills have come down significantly and we immediately noticed the upstairs being much warmer even without turning up the heating during colder days. The upstairs is also much cooler during the hot summer days as the air does not escape through the attic as it once did. GNI did a wonderful and professional job and have saved us a lot of energy costs and the insulation pays for itself over a few years. Best way to save on energy costs without spending a lot of money.
