Basement Rim Joist

box still foam

In many homes across southeast Wisconsin, basements are cool, damp and not very comfortable. While many basements are designed for housing mechanicals like furnaces, water heaters and laundry appliances, they can also provide extra living space for families. Making sure these areas are comfortable and properly insulated is crucial. That's where Wisconsin Home Improvement comes in!

Proper Basement Insulation Improves Moisture Control

Even though basements appear to have good insulation, concrete has a relatively low R-value (a measure of thermal resistance) and the added element of moisture can make basement living areas uncomfortable. Fortunately there are plenty of options to improve the comfort and energy efficiency of basements with specific types of insulation products. Wisconsin Home Improvement has the expertise to help seal off basement areas from dampness and add insulation to transform your basement into a comfortable, safe living area.

What Kind of Insulation?

For basements in the Menomonee Falls and Pewaukee area, 1.5 to 2 inches of Thermax™ can provide R-15 to R-19 level of insulation recommended by the Department of Energy. Thermax™ consists of a rigid foam insulation board with smooth aluminum foil facings on both sides that can help to maintain proper humidity control.

In the box sill areas, where the basement walls meet the floor, the best solution is an application of Icynene spray foam to insulate and seal areas where exterior grading might allow water in. A well-insulated and moisture-controlled basement can contribute to a comfortable, efficient home.

Where in the Basement Will I Need to Insulate?

A home performance audit with our team will reveal areas in the basement where excess moisture is collecting. If the basement floor is dirt, we can apply a 6-mil layer of plastic to the floor and interior walls before installing the Thermax™ insulation rigid foam sheets. Depending on whether the basement is heated and cooled or not, the underside of the main level floors may also require additional insulation in the form of fiberglass batts or spray foam.

    Dear Steve, 

    We at Grace are so pleased with the quality of work and the professionalism of the crew that did the insulation. Mike and Igor were so respectful of the building and its contents, and so nice to everyone in the congregation who was working at church.

    I really feel compelled to give a "shout out" to everyone I have come into contact with at WHI. First off - Jody. You are so friendly and helpful on the phone, forgiving me for my inability to "on-line sign", switching up of dates, declining work and then changing my mind.

  • Tim S.

    Steve, just a side note and I would not send this if it was not completely true - Mike and Pete were both fantastic. I was impressed. We had just had other major construction and have many comparatives for the work WHI did. I would come home and never know they had even been there.

  • Mike & Erin M.

    We wanted to provide feedback on our experience with Peter, who did our home energy audit.  We felt he went above and beyond what was expected of him.  He was very thorough and was genuinely concerned about any issues causing inefficiencies in our home.  He explained things in terms we...
