Can’t I add insulation on top of my existing attic insulation?
If you are considering adding insulation to your attic, chances are you are experiencing some comfort concerns. Maybe your daughter’s bedroom is freezing cold in the winter or your master bedroom is too hot in the summer. Depending on the condition of your existing attic insulation, simply adding more insulation on top of your existing insulation could be like throwing a rug over a hole in the floor without repairing the floor…It may look better on top, but it’s still going to be quite uncomfortable and dangerous when you step into the room.
When should you remove your existing insulation?
Sometimes it can be perfectly fine to reuse your existing attic insulation, but in the following cases we recommend you remove the bad stuff and start with a clean slate:
- Traces of critters or rodent damage
- Water damage
- Sensitivity to dust or allergens
- Poorly installed insulation
While critters and water damage may seem like more obvious reasons to remove your insulation, the most common, and unfortunately most overlooked reason to remove your existing attic insulation is that the insulation you have was not properly installed. Not all of the rolled-out pink stuff is created equal.
Don’t make the common mistake of covering up poorly installed insulation.
Fiberglass is a very common type of insulation used in attics because it’s cost-effective and easy for builders to have installed. For fiberglass insulation to be effective it needs to be fluffy and in contact with the surface, it’s trying to insulate. The construction and tight spaces of your attic make it challenging to achieve these basic requirements. During our comprehensive home energy audits, we typically find fiberglass insulation compressed under plumbing and electrical wiring and bridged over joists and light fixtures. These obstacles are prevalent throughout attics causing hundreds of efficiency leaks that can add up to a big waterfall of energy loss and uncomfortable rooms.
