Insulation materials play an important role in determining the comfort of your home. Wall insulation helps to prevent the transfer of heat between your home's interior and the outside environment. This keeps your interior living spaces warm during the winter and cool during the summer.
The more energy-efficient your insulation is, the less you will pay in heating and cooling costs over time. Maximize the efficiency of your wall insulation by keeping these useful tips in mind.
1. Ensure an Exact Fit
Every open space within your walls should be insulated if you want to maximize the amount of heat transfer that is eliminated. Your wall cavity is not just a single open space. There are several studs and support structures that create smaller compartments within the wall's design.
You will need to trim fiberglass insulation so that it is an exact fit. A strip of insulation that is too wide can lead to crumpling and the creation of uninsulated air pockets. A strip of insulation that is too small can leave gaps where heat can escape. Measure each opening carefully, then cut the insulation to the exact specifications for maximum efficiency.
2. Pair With Spray Foam
You may notice that there are some small gaps between the insulation and window or door frames. Fiberglass insulation sheets are often too large to fit securely inside these small gaps. You will need to pair the fiberglass insulation with a specialized spray foam to reach maximum efficiency.
Use a minimal-expanding insulation product to prevent the door or window jamb from warping. The combination of fiberglass insulation with spray foam can create an airtight-insulated cavity within your walls.
3. Split to Accommodate Pipes and Cables
A series of pipes and cables run through the interior cavity of all residential properties. These pipes and cables can pose a unique problem when it comes to adding fiberglass insulation.
You don't want to stuff the insulation behind pipes and cables, and you don't want to lay the insulation over the top of these structures either. Both methods will create air pockets that allow heat transfer to occur.
Split a sheet of insulation in half, then sandwich the pipe or cable between the two halves. This approach will maximize the efficiency of the insulation while preserving the function of your pipes and cables over time.
The right approach to wall insulation can maximize the energy efficiency of your home in the future.
