Properly insulating your house is one of the most important steps to take to have an efficient home. Insulation works like a blanket to keep the warmth inside your home during the winter and the heat outside during the summer. Insulation is measured in R-values, which is simply a measurement of how much resistance it has to heat transfer. The higher the R-value number, the more effective it is in stopping heat.
What Types of Insulation are Available?
Insulation is available in many forms to keep your home cozy and comfortable all year long.
Blown-in insulation is available in both cellulose and fiberglass. Loose fill, blown-in insulation is convenient and effective for attic applications. Because it can be applied at any depth, it can be easily customized to a specific insulation level. Blown-in insulation also provides seamless cover over existing insulation products.
Fiberglass Batt Insulation
Fiberglass batt insulation is used for many different applications and is sized to fit between studs and joists. Fiberglass batts come in a range of R-values for different locations. Fiberglass batt insulation performs at its peak when enclosed on all six sides.
Radiant Barrier Insulation
Insulation that is combined with a reflective radiant barrier makes a superior shield against hot summer attic temperatures. By reflecting 97% of the radiant heat entering your attic, it can lower your attic temperatures by as much as 30 degrees.
How is Insulation Installed?
To be most effective, insulation needs to be properly specified and installed by an experienced insulation contractor. It’s a very common problem in our area—when installed improperly or in the wrong place, insulation just doesn’t do its job. The insulation team at Energeyes works with existing homes in the North Raliegh, NC area every day, and we understand how and where to install your insulation to provide top performance, comfort and energy savings. Here are three keys for effective insulation installation:
Contact — Insulation must be in contact with the interior house walls. Insulation that is is pulling away from the walls or falling down beneath your house is not functioning. Anytime air can move between the insulation and the drywall, it becomes ineffective.
Continuous barrier — Insulation must be installed to provide continuous, even coverage without being compressed. When insulation is compressed, the air pockets that create the R-value can’t prevent heat transfer.
Air sealing and ventilation —Insulation must be installed with proper air sealing and ventilation. Air sealing prevents air from leaking in and out. It allows insulation to perform to its specified R-value. Attic insulation should have baffles or blocking to provide continuous ventilation. Walls that are adjacent to the attic require an air barrier to prevent the insulation from falling and to keep air from penetrating.
