When faced with warm weather, your HVAC system works harder to keep you comfortable. One way to ease the workload on your equipment: add more attic insulation.
Chances are the attic insulation in your home was installed when your home was built, and the contractor probably used only as much as the building code mandated. Building codes only serve as minimum requirements. It’s perfectly acceptable and advisable to install extra insulation in the attic. When you boost the attic insulation, you not only decrease the workload on your HVAC system, but you’ll decrease your energy bills as well.
When the sun heats your roof, the temperature in your attic space can climb to 150 degrees or more. With nowhere to go, that heat will transfer itself into the building components (trusses, rafters, ceilings, etc.) and then radiate into your living space. This means your home’s A/C unit must work harder to reach the temperature on the thermostat.
During heating season the same principle applies, only in reverse. Extra attic insulation will keep your heat from rising into the attic, sending your heating bills through the roof.
The most common way for a homeowner to increase their attic insulation is with fiberglass blankets, or batts, available at your local home improvement retailer. Regardless of what type of insulation you currently have, or how much, you may still be able to add a new 6″ (or more) blanket to it. The added R-value — the insulation’s resistance to heat flow — will save you money in heating and cooling costs and increase the life span of your equipment.
