A well-insulated attic significantly reduces air movement throughout the home. As the warm air rises in the winter, it will find any path it can to escape. When the attic is air-sealed and insulated, the energy used to warm the air remains in the living space, right where you want it! This saves the heating system from working overtime and keeps your utility bills low.
R-value is a measure of insulation’s resistance to heat flow. For gas and oil heated homes in the Northeast, an R-value of 38 is recommended. For homes with electric heat, an R-value of 49 is suggested. We primarily use two types of insulation at Energy Protectors. Fiberglass batts provide an R-value of 3.1/inch compared to Cel-Pak cellulose which provides 3.8/inch.
Prior to insulating, proper ventilation must be installed in the attic. Air must be free to flow from the soffit to the ridge, unobstructed by the new insulation. This can be achieved by installing baffle vents in each rafter bay. Baffle vents channel air while preventing insulation from covering the soffit.
