If you’re remodeling your home, or just looking to save on your energy bills, updating the insulation in your basements and crawlspaces should be a priority. We’ve discussed insulating your attic, but, according to energy.gov, insulating your basement or crawlspace is just as important. As usual, we’ll highlight a few products that we trust can help you get the job done in 4 unique scenarios!
Insulating Exterior Foundation Walls
For this job, we recommend using Owens Corning’s FOAMULAR rigid extruded polystyrene foam. That’s a mouthful, but it sure gets the job done! This insulation is great for installing directly against the concrete foundation walls. It can withstand long-term exposure to moisture and decay from soil.
Insulating Interior Basement Walls
Inside a heated basement, assuming that your foundation walls have already been checked for any water leakage, you should install Kraft paper-faced or unfaced exterior wall insulation between 2×4 wall studs. Remember, you don’t need to insulate the ceiling of a heated basement, but doing so will quiet the noise from people walking on the next floor.
Insulating Conditioned Crawlspaces
If your crawlspace is heated, or one which does not have insulated ducts or water pipes, then you should insulate the walls in order to keep the space warm. We recommend EcoTouch PINK FIBERGLAS insulation, which will help keep the energy from escaping through your pipes and ducts.
Insulating Unconditioned Crawlspaces
In an unheated crawlspace, the cold air will rise up through the floor into your home, and forcing your heating system to work harder to maintain a comfortable temperature. To combat this, add batts of the same EcoTouch PINK FIBERGLAS insulation that we recommended above between the joists in the ceiling.
Following the simple tips above, you’ll cut back on your energy bills and save money, with just a few hours of work invested!
