If your attic insulation is inefficient due to faulty installation, then how can you really save on your energy use? Fortunately, there are a few ways to maximize what energy efficiency your insulation has regardless of its installation:
Keep your attic storage-free
You might consider turning your attic into a storage site or an extra bedroom. However, your contractor generally sets up insulation in the attic because it is close to your ceiling and your roof. Your contractor can only do that if no heavy items are bearing down on the insulation material.
Maximize your insulation’s R-value
If you have a new home, head to the attic and identify the type of insulation there. Specifically, try to measure its R-value by looking up charts that indicate typical R-values of common insulation materials per inch of depth. Also get rid of any moldy, wet, or compressed insulation there.
Seal any air leaks
Look for any air leaks in the attic. Your attic insulation will not deliver much savings unless you or your professional seal all those air leaks. Among the likely places for leaks to occur are the attic entrance, vent ducts, water and furnace flues, and window frames.
By following the above tips, you can still keep your insulation energy efficient despite the way it was installed.
