There are very few home renovations that pay for themselves and boost your home’s value over time: one that does, however, adding attic insulation can accomplish this. It’s not the most beautiful home improvement project, but it’s the best investment. If you’re ready to add some insulation to your home to save on energy bills, you might save even more money by doing it yourself — at least for the attic.
Think of attic insulation as a thick blanket over your house that holds in heat in the winter but keeps it out in the summer. Adding insulation to the walls is best left to the pros, but once you understand how to insulate the attic, you can do this yourself in a weekend if you’re handy. Keep these tips in mind to get this smart home improvement job done right:
Fiberglass insulation works well to keep in heat, but it can be incredibly irritating to your skin. Wear long sleeves and pants as you work with it, and invest in a good pair of work gloves to protect your hands — otherwise you’ll be very itchy. A respirator mask is also a good idea.
Choose the Right Insulation:
You can use loose fill or batts, which comes in paper-backed rolls. If you have regular joists that are 16 inches apart, batts will be easier to work with. If you have an older property or lots of odd corners and acute angles, blowing in loose fill could be faster.
Seal Out Drafts First
Before you roll out insulation, check for cracks or any broken spots that could be letting in drafts — sunlight shining through is a good indication that you have a breach. Use a can of expandable spray foam to seal these areas first to help your new insulation work better.
Maintain Air Flow
Be sure that you don’t block off any vents in your attic as you install insulation. These are crucial for keeping moisture levels appropriate in the space, and soffit vents help prevent ice dams. Use rigid foam baffles to preserve proper air flow.
As always, measure twice and cut once! Once you’re finished, you should notice an immediate drop in your utility bills, which will prove you did a good job on your insulation project.
