A good foundation has insulation.

Properly air sealing vulnerable spots in your home can significantly reduce heating and cooling costs and create a healthier indoor environment.

First, we recommend a home performance test. The test includes depressurizing your home to measure air changes per hour, infrared scanning to identify air loss, insulation level evaluation, humidity testing, and combustion safety check. Then, we give you educated recommendations for optimum energy efficiency. We can usually improve on both the interior and exterior of your foundation. It will save you energy and money, while also making your basement more comfortable. Foundation insulation may even qualify you for rebates.

Interior Benefits of Foundation Insulation: On the interior of your unfinished concrete/block walls, we recommend the installation of a Thermax foil faced foundation insulation. It's the only product that has been fire tested, allowing you to leave it unfinished. Any other choices of foam board like Johns Manville or Pink board work equally as well, but you must install a fireproof finish such as drywall over them after the installation.

Exterior Benefits of Foundation Insulation: We install 1-inch rigid foam around the exterior perimeter of your home to a minimum of 10 inches below grade. After installation of the foundation insulation, you will instantly notice a much more comfortable basement, because the warm to cold transfer can no longer take place. This can drastically improve the comfort of your home. We offer a crushed rock or stucco finish as our standard option and can install custom colors to match almost any color scheme.

Rock & Tait also provides air sealing, blown-in insulation, dense pack insulation, and spray foam insulation.

Great job on a very large re-roof that was done perfectly.  Done in March-April 2018 during the time of the great snow falls.  Everything was done perfectly by Trevor and his team.  We were kept appraised with comments and pictures as we were not home when they did the work.  Included a new roof, all new gutters and guards, re-insulation of our great room and installation of a solar tube in one bathroom.  Could not be happier knowing they use their own crews and stand behind the work they do.  GREAT JOB!

Rock & Tait insulated and dry-walled my garage. It made a huge difference in the temperature inside the garage. Work was done quickly and clean-up was done promptly. The cost was minimal and saved me many labor hours. I highly recommend Rock & Tait!

Mike Drexler

I started out with Steve, he was the only contractor to repair the bedroom ceiling without ripping out all of the dry wall, that really was a game changer for me.  Steve also gave up time to work with the insurance company which ensured coverage minus the deductible.   When the job was started, the crews and crew leaders were exceptional and very respectful.  All of them understood their jobs and got to work.  I will always be grateful for their work ethic. I would never hesitate recommending Rock & Tait. Thank you so much for a job well done!

We have had Rock and Tait do a few updates to our house. Even though it was a new house when we moved in, years later we realised some upgrades were necessary. Kane himself has helped us with suggestions that have really proven the right way with today's technology. And when we recently needed some adjustments to a prior install, again Kane showed up first to assess, and then said he'd get us scheduled. The issue was upgraded, fixed, and resolved. With all the places you can read or hear about on social media, it's nice to know the owners keep it contact with their customers.

My house was built in the 1930s and likely hadn't been meaningfully insulated since. This year, I decided to bite the bullet and get it done (plus attic venting, bathroom fan, and basement crawl space insulation). It's only been finished for a few weeks, but I can definitely feel the difference already! With gas bills skyrocketing this winter, I'm very much looking forward to seeing what a difference this will make. Rock & Tait did a great job, and I'm so thrilled to have this finished!

Laura Buchholz

I have used Rock & Tait for four home renovation projects. They are amazingly professional and organized. Their representative comes prepared with the proper paperwork spelling out in detail all the work to be completed. They assist with filing insurance claims, have professional workmen, and leave a clean work area. The products they sell are top-notch. I have had other companies bid out projects, but no one compares to the service, quality, and organization of Rock & Tait.

Margaret Quaid

Rock & Tait put together an itemized estimate for us based on our energy performance test results. We were able to prioritize the items completed and went from a 1575 CFM -ACH of 4 down to 792 CFM -ACH of 1.9 = 51% reduction in air loss! Our heating and air system doesn't have to run as hard or as long as before = $$$ saved. I couldn't be happier that I selected Rock & Tait. Their ability to do it all made the entire process easy.

Rick Podolak

The crew came and asked for direction to ensure they were in the right space, let me know how the progress was going and helped clean up some brick dust mess that was unexpected. They were kind and respectful and thanked me when they left. We had four inches of spray foam insulation out on our ceiling of our business, which was a large job. Our gutter work looks nice too.  

Rebecca Gudis

Our experience with Rock and Tait was positive all the way around. They arranged for an energy audit and followed up with recommendations. They communicated the plan and kept us up-to-date with progress. Everyone on the crew was professional and friendly. We had our 1960s house reroofed, some windows and a storm door replaced, the attic insulated, ventilation added, and exhaust fans installed. I would work with them again!

Joyce Olson

Our experience with Rock & Tait was outstanding. They laid out every detail for the job, then worked to give us the best service and product within our budget. There was no pressure at all. Both of the crews we had (insulation and exterior work) were outstanding! When they were done, it was as if they were never here - minus the incredible work they did! I would highly recommend Rock & Tait for any of your jobs!  

Chad Semling

I had an energy assessment earlier this spring and after receiving my detailed assessment I reached out to Rock & Tait. Our project was more than just insulating due to some complex design flaws within our home. The service was excellent and their communication throughout the project exceeded expectations. They were meticulous in the details and it showed in our follow-up energy assessment. Well worth the investment!

Jeffrey Henon

The Rock & Tait team that came to our house to redo our attic insulation and ventilation did a fantastic job. The team was troopers crawling into some tight spaces to make sure our house would be airtight. We were also very impressed with the quality of work and craftsmanship on our awning that needed to be replaced. We can't recommend them enough!

Foundation Insulation FAQ

What is foundation insulation?

Foundation insulation is insulation installed along the interior or exterior of your home's foundation walls to reduce heat loss, improve energy efficiency, and create a more comfortable basement or crawl space. Proper foundation insulation is an important part of a complete home insulation strategy because it helps reduce energy loss where your home meets the ground.

Can foundation insulation lower my energy bills?

Yes. Foundation insulation reduces heat transfer through basement walls, helping your heating and cooling system operate more efficiently. Combined with proper air sealing and attic insulation, it can significantly reduce energy loss and improve your home's overall efficiency.

Should I insulate the inside or outside of my foundation?

Both interior and exterior foundation insulation can be effective, depending on your home's construction and project goals.

  • Interior foundation insulation is commonly installed on unfinished basement walls using rigid foam insulation such as DuPont™ Thermax™, which is approved to remain exposed without drywall in many applications.
  • Exterior foundation insulation uses rigid foam installed around the outside of the foundation to reduce heat transfer before it enters the home.

During a home evaluation, we'll recommend the solution that best fits your home's needs.

What are the benefits of foundation insulation?

Foundation insulation provides several important benefits, including:

  • Improved energy efficiency
  • Lower heating and cooling costs
  • A warmer, more comfortable basement
  • Reduced drafts and cold floors
  • Better moisture control
  • Improved indoor comfort year-round
  • Potential eligibility for energy-efficiency rebates

Foundation insulation works best when combined with proper air sealing and other insulation improvements.

Why is foundation insulation important?

Many homeowners focus on insulating their attic but overlook the foundation. An uninsulated foundation allows heat to escape through basement walls and floors, making your home less comfortable and increasing heating and cooling costs. Proper foundation insulation helps improve indoor comfort, lower energy bills, and reduce temperature fluctuations throughout the home. 

Will foundation insulation make my basement more comfortable?

Absolutely. Many homeowners notice their basement feels noticeably warmer in winter and more comfortable year-round after foundation insulation is installed. Reducing heat transfer through foundation walls also helps make first-floor rooms above the basement more comfortable.

Does foundation insulation help with moisture problems?

Foundation insulation can help reduce condensation on basement walls by keeping interior surfaces warmer. However, if your basement has water leaks or drainage issues, those problems should be addressed as part of a complete moisture management plan before or alongside insulation improvements.

How long does foundation insulation last?

Quality foundation insulation is designed to last for decades when properly installed and protected from damage. It requires very little maintenance and continues providing energy savings and improved comfort for many years.

What insulation products does Rock & Tait use for foundation insulation?

For unfinished basement walls, Rock & Tait recommends DuPont™ Thermax™ foil-faced foundation insulation because it has been fire tested and can often remain exposed without requiring drywall. For exterior applications, rigid foam insulation is installed around the foundation perimeter to improve energy efficiency and basement comfort.

Should I have a home energy evaluation before adding foundation insulation?

Yes. Rock & Tait recommends starting with a home performance evaluation that measures air leakage, insulation levels, humidity, and overall home efficiency. This helps identify where your home is losing energy so improvements can be prioritized for the greatest benefit.

Is foundation insulation a good choice for Wisconsin homes?

Yes. Wisconsin's long, cold winters make foundation insulation an excellent investment. By reducing heat loss through foundation walls, homeowners can enjoy improved comfort, lower energy bills, and a more energy-efficient home throughout every season.

Can foundation insulation increase my home's value?

Energy-efficient improvements such as foundation insulation can make your home more comfortable and attractive to future buyers. Lower utility costs, improved basement comfort, and better overall home performance are valuable long-term benefits.

Why is professional foundation insulation installation important?

Proper installation ensures insulation is placed correctly, vulnerable air leaks are addressed, and moisture concerns are considered before installation. Professional installation also helps maximize energy savings and ensures the insulation performs as intended for years to come.
