Replacing Your Attic Insulation

OAKLAND — Does the inside of your home get hot in the summer and cold in the winter? One thing to check is the condition of your attic insulation. The attic is the first place where conditioned air escapes to, so if yours isn’t properly insulated, it can be difficult to maintain a comfortable indoor climate. It can also require your furnace or air conditioner to work harder to maintain your desired temperature. If your attic insulation is thin, outdated or in generally poor condition, you should consider replacing it. Not only will your home be more comfortable in the warmer and cooler seasons, but you’ll save money due to reduced energy bills.

Types of Insulation
There are two types of insulation commonly used in attics. One is batting insulation, which comes in the form of large blankets or “batts.” The other is blown-in insulation. Instead of large, uniform blankets, blown-in insulation consists of loose pieces of insulation that are literally blown into the attic with a machine. The advantage of this type of insulation is that it can fill in smaller gaps.

Both batting and blow-in insulation can be effective for insulating your attic, so the one you choose will depend on your attic’s structure and how accessible it is. Your insulation contractor can help you determine the best choice for your situation.

The Insulation Replacement Process
The process of replacing attic insulation is fairly simple. After assessing the attic for any potential hazards, a contractor will use a large vacuum to remove the old insulation. Next, they’ll air seal the attic space using expansive foam and caulking; this will help prevent air leakage and improve energy efficiency. If your attic had any signs of rodent infestation, the contractor will also disinfect the area to eliminate any hazardous germs and foul odors. Finally, they’ll install the new installation.
