Remodeling your home brings exciting visual changes for sure, but did you know that it’s also one of the best times to update your insulation? Considering that 90% of homes are under-insulated, this is the perfect opportunity to add more insulation while attic roofs and wall studs are open and exposed. The insulation pros at A+ Insulation have some great tips for insulating during a remodeling project. There are two basic areas to consider; the walls and the attic.
Insulating the Walls During a Remodel
If you’re replacing drywall or building new walls, make sure you get the insulation right. Remove all old, wet, or compressed insulation. While you have this opportunity, it’s best to install new insulation so you know it’s all fresh (no mold here) and meets the recommended R-value.
Fiberglass batts or rolls are usually the easiest for homeowners to install. Spray foam will give you even better insulating results, as it expands to fill in any nooks and crannies and seals as it dries forming a vapor barrier. Though spray foam costs more as it is not a DIY kind of product, it will yield the best R-value.
Attic Remodel Tips for Insulation
Attic insulation is critical to keeping your home comfortable especially in the winter months since heat rises and escapes through the roof. Your choice of insulation will depend on the roof framing system.
If the roof is framed with rafters, and the floor space is open, and you can lay insulation batts between the horizontal joists. If the floor is finished, focus on adding insulation to the ceiling of your attic, between the sloped rafters. If you plan to finish a living area in the attic, use paper-faced fiberglass batts in the rafter space, with the paper side facing downward.
If you have roof trusses, blown-in cellulose fiber works well because cutting and laying fiberglass batts in a trussed attic can be labor intensive and tedious. Blown-in insulation creates a uniform blanket of insulation, and it can get into smaller spaces as well. Just make sure that insulation doesn’t block soffit vents or cover heat-producing lights.
Many times, the homeowners start their project only to find their insulation is thicker than the depth of the rafters. To keep the insulation flush with the ends of the rafters so drywall can be added later, furring (attaching strips of wood to add depth to the space between the roof and the rafters to match the depth of the batted insulation) may be necessary. To insulate without furring the rafters, you can install regular batts in the existing rafter spaces, and then add a layer of rigid foam board insulation over the rafters for added R-value. Drywall can be installed on top of the boards for a finished attic.
Add Exterior Insulation with New Siding
If you are adding new siding as part of your remodel, make sure it’s insulated. You can buy insulated vinyl siding that comes with rigid foam attached to the back for additional insulation. It’s a great way to add another layer of thermal protection to your home that’s offered by many different manufacturers.
