Blown-in Insulation FAQ's
Q: How does insulation really work?
A: Insulation creates a physical barrier against conductive and convective heat. Conductive heat travels from one surface to the next and convective heat travels on air currents.
Q: What is R-value?
A: Insulation is rated by its R-value, which is a thermal resistance measurement, or its ability to resist heat flow. The higher the R-value, the greater the resistance. According to Energy Star recommendations, most attics require R-38 , which is about 12” of thickness, depending on the insulation type.
Q: I’ve lived in my home for 30 years, but it seems like it’s getting harder to stay warm in the winter. Could the insulation be the problem?
A: Absolutely! Many homes built in the ‘70’s, ‘80’s, and even in some cases the ‘90’s were insulated with less than R-38 values in the attic. Additionally, it’s very possible that the insulation in your attic has compacted or shifted over the years, which means its effectiveness has been compromised.
Q: I already have insulation in my attic, but I know it isn’t deep enough. Do you have to remove the old insulation before you add the new?
A: No, as long as the insulation in your attic is fiberglass, we can just supplement it with like materials.
Q: Are there different types of blown-in insulation?
A: Yes, there’s cellulose, rock wool and fiberglass. We choose to use fiberglass insulation because it doesn’t hold moisture and is less likely to compact over time.
Q: Are there energy credits for installing insulation?
A: Yes, in 2009 and 2010! For existing homes, and for 30% of the cost of materials, up to $1500!
