Types of ENERGY STAR Attic Insulation
Attic Insulation is an often overlooked space in your home. Most homeowners don’t consider it until a problem occurs, such as a ceiling leak or a rodent infestation. But a properly insulated attic is an important part of your home’s comfort, energy efficiency and moisture control.
Attic insulation is one of the most cost effective upgrades you can make to your home, and it can significantly reduce air leaks that waste energy. Low attic insulation levels and air leaks cause your heating and cooling system to work harder, which drives up energy costs. Proper attic insulation can save you up to 20% on your energy bills.
The Benefits of Spray Foam Insulation for Your Attic
Fiberglass batt insulation is the most common attic insulation type. It’s made of small glass fibers that are blown into the attic or placed between wall studs. It’s relatively inexpensive, but prone to settling over time and may need top-ups. Fiberglass is also not resistant to moisture, and when wet it can lose its effectiveness.
Mineral wool attic insulation is composed of rock mineral materials that offer high thermal resistance. It is often installed in new homes, but can also be a great option for insulating older attics.
Rigid foam attic insulation is panels of polystyrene, polyisocyanurate or polyurethane. It’s a good option for insulating existing attics that are open and free of obstructions, and is relatively easy to install. It does emit gases during and after installation, requiring adequate ventilation. The table below shows various types of ENERGY STAR certified insulation and their relative insulating properties, as well as the varying degrees of skill needed to install each.
