When talking about insulating a home, most people think about attics and walls. But insulating the floors over the basement or an unconditioned crawlspace can improve your home's comfort and improve energy efficiency. Sealing up the gaps and spaces where air can infiltrate into the main floor living areas can also prevent moisture and mold from building up.
High-Performance Floor Insulation Improves Comfort & More
If your home feels cold and drafty, deficient floor insulation is one place to look. Wisconsin Home Improvement's home performance audit will help identify overlooked and under-insulated areas in your home, from top to bottom, including floor areas that separate conditioned spaces from those that are not heated or cooled.
Underfloor insulation can improve the cozy feeling of rooms that might feel drafty or damp. By placing a radiant barrier between the main level and basement or crawlspace level, our certified and trained team also can keep moisture and mold from seeping up into main living areas.
Here are just a few of the benefits you can expect when you have well insulated floors:
Warmer floors in your living spaces
An overall cozier feeling home
Increased home energy efficiency
Greater utility bill savings
How Much is Enough Floor Insulation?
Most floors can hold quite a bit of insulation between supporting joists. Insulation board is one option for adding insulation to floor areas. For new construction, R-49 is required to meet energy efficiency codes, but most retrofit options will add the equivalent insulation of R-19 to maximize comfort.
What Kind of Insulation Is Best?
Wisconsin Home Improvement has several options to recommend for floor insulation. Dow Thermax™ rigid foam insulating panels, which have an aluminum foil facing on both sides and are available in different thicknesses and R-values, is one great choice. Owens Corning fiberglass batts, which can be fitted between joists, are another excellent option. If the underfloor floor area is adjacent to a crawlspace, an Icynene spray foam insulation application provides both added comfort and a barrier for moisture.
Where in the Floor Will I Need to Insulate?
Insulation should be applied to floor areas that are adjacent to heated areas. Most times, insulation is placed between floor joists, around any ductwork and air returns, plumbing, wiring and other components that are attached to the floor structure. In places where the floor connects with the foundation walls, we typically use fiberglass batts or spray foam Icynene insulation.
