Attic Insulation

attic insulation in Wisconsin

The attic can be the site of a good portion of your home's heat loss and energy inefficiency, primarily because heat rises. Poorly-insulated homes can lose as much as 25% of their energy through the roof and attic! For this reason, our team pays special attention to everything directly under the roof when we conduct a home performance audit.

Proper Attic Insulation Improves Comfort

Our home performance audit will measure and review your attic's current insulation as well as identify areas where conditioned air is leaking from your home's living areas. We'll determine the proper R-value -- or measure of thermal resistance -- that is needed for your home's attic. Generally speaking, new homes in our area need R-49 thickness of insulation to meet energy efficiency codes. Most existing homes will be comfortable with R-30 levels of insulation in the roof and attic, especially when the gaps and cracks are sealed.

Local codes may vary; our team will be sure to check to see what the requirements are in your area.

What Kind of Insulation Should You Choose?

There are many types of insulation on the market today, and all perform in different applications. Since most attics already have some insulation in them, oftentimes new insulation can be added right on top to total a thicker layer and higher R-value. However, if the insulation is damaged by water, is moldy or has compressed too much, it may be best to remove it and replace it.

Here are our preferred types of high-performance insulation:

Fiberglass Batts or Loose FIll

As an Owens Corning Certified Energy Expert, we have the expertise to properly apply fiberglass insulation to ensure a comfortable home.

Icynene Spray Foam Insulation

For some attics, closed cell spray foam is a great solution to not only insulate, but to also provide an impenetrable barrier to pests, noise and tiny, invisible leaks.

Cellulose Insulation

Made from recycled paper and treated to be mold and fire-resistant, cellulose can be applied on top of existing attic insulation.

Where in the Attic Will I Need to Insulate?

Attic insulation is most commonly applied to the "floor" of the attic space to insulate the ceilings of living areas below. If the attic includes living spaces that have been finished off, the ceilings, knee walls, dormer walls and areas beyond the visible ends of joists should also be treated with added insulation.
