Six Common Attic Insulation MistakesSix Common Attic Insulation Mistakes
Insulation is a hugely important part of energy efficiency, helping to regulate indoor temperatures and keeping the HVAC system working smarter. However, improper installation can actually reduce a home’s energy efficiency and lead to costly problems in the future. Here are six common mistakes that do-it-yourselfers and even some professional contractors make when insulating attics.
1. The insulation is not in contact with the attic floor.
Insulating an attic roof installation fully sealing the area under the attic floor is a major mistake that wastes money and creates ice dams. Insulation should be cut and fitted to cover the entire attic floor, making sure it’s in direct contact with the drywall ceiling below.
2. The attic vents are blocked or obstructed.
Every attic needs a minimum of one attic vent to allow fresh air into the attic, helping to prevent condensation and mold buildup. These vents should be positioned in the soffit, along the underside of the eave or on the ridge of the roof. If the existing attic ventilation isn’t sufficient, additional vents should be installed.
3. The attic knee walls are not properly sealed.
Knee walls (half walls in the attic) should be insulated on the nonliving side, but gaps around the penetrations of wires, pipes, ductwork and recessed lights allow warm air to seep into the attic. These gaps should be tightly sealed with aluminum flashing and high-temperature caulk.
Getting old, wet or moldy insulation out of an attic isn’t always easy, and it’s not something you want to try on your own. If you’re not sure what you’re dealing with–especially if it looks like contaminated vermiculite or asbestos–it’s best to let a trained professional handle it.
