Dense pack insulation creates a complete air seal, eliminates air infiltration, and maximizes R-value — meaning less heating and cooling losses for a more comfortable home environment and a lower energy bill.

Not only will your energy bill be lower with dense packing insulation, but your home will have a layer of protection against moisture, mold, pests, and fire. The exterior walls of your home are insulated by drilling holes and then blowing loose fiber insulation into the wall cavities at high pressure. When cellulose insulation is pneumatically installed at high velocity to densities greater than 3.5 pounds per cubic foot, it acquires a unique air sealing property. In this process, the material behaves as a liquid, flowing into obscure bypasses and solidifying them.

Why cellulose and not fiberglass? Cellulose has a higher density than fiberglass, making it the better insulator. Made from recycled paper saturated with fire retardant, it cannot be started on fire even with a propane torch. It also guards against vermin and is moisture resistant, preventing mold, rotting, and odor.

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

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.

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

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!

Thomas Kell

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!

Justin Kaatz

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!

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

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

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

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

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

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!

Paulette Wagner

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.

We begin with a comprehensive evaluation of your home's energy performance to determine where insulation improvements will have the greatest impact. Whether you're upgrading an older home or improving the efficiency of your current home, our experienced team delivers quality workmanship, personalized recommendations, and lasting results that help keep your home comfortable in every Wisconsin season.

Why is professional dense-pack insulation installation important?

Proper dense-pack installation requires specialized equipment and experience to achieve the correct density throughout each wall cavity. Professional installation helps ensure the insulation performs as intended, providing effective air sealing, consistent coverage, and long-lasting energy savings.

Can dense-pack insulation increase my home's value?

Improving your home's comfort and energy efficiency can make it more attractive to future buyers. Dense-pack insulation is a long-term investment that helps lower energy costs, improve indoor comfort, and increase your home's overall efficiency.

Should I have a home energy evaluation before adding insulation?

Yes. A home performance evaluation can identify where your home is losing energy and determine whether dense-pack insulation, attic insulation, air sealing, or another upgrade will provide the greatest benefit. Rock & Tait evaluates your home's overall energy performance before recommending insulation improvements.

How long does dense-pack insulation last?

When professionally installed and kept dry, dense-pack cellulose insulation is designed to last for decades. Because it is installed at a high density, it resists settling and continues to provide reliable insulation and air-sealing performance over the long term.

How is dense-pack insulation different from blown-in insulation?

While both use cellulose insulation, they serve different purposes. Blown-in insulation is typically installed in open attic spaces, while dense-pack insulation is installed under higher pressure into enclosed wall cavities. This higher density helps minimize air movement within the walls and provides improved insulating performance.

What are the benefits of dense-pack insulation?

Dense-pack cellulose insulation offers several advantages, including:

  • Helps create a tighter air seal
  • Reduces drafts and air infiltration
  • Improves energy efficiency
  • Lowers heating and cooling costs
  • Helps reduce outside noise
  • Adds protection against moisture, mold, pests, and fire
  • Made from recycled materials

These benefits make dense-pack insulation an excellent solution for improving comfort and reducing energy loss in existing homes.

What is dense-pack insulation?

Dense-pack insulation is a method of installing cellulose insulation into enclosed wall cavities using specialized equipment and high pressure. The insulation is packed tightly to reduce air movement, improve thermal performance, and create a more comfortable, energy-efficient home. Unlike loose-fill insulation, dense-pack insulation is specifically designed to fill wall cavities without settling over time.

Where is dense-pack insulation installed?

Dense-pack insulation is most commonly installed inside existing exterior wall cavities. Small access holes are drilled, and cellulose insulation is blown into the wall under pressure until the cavity is completely filled. This allows homeowners to improve insulation without removing large sections of drywall.

Is dense-pack insulation a good option for older homes?

Yes. Dense-pack insulation is especially popular for older homes that have little or no insulation inside the walls. It provides an effective way to improve comfort and energy efficiency without major remodeling, making it an excellent upgrade for many Wisconsin homes.

Is dense-pack insulation environmentally friendly?

Yes. Dense-pack cellulose insulation is one of the most environmentally friendly insulation products available. It is manufactured from up to 85% recycled newspaper and treated with borate minerals for fire and pest resistance, helping reduce waste while improving your home's energy efficiency.

Does dense-pack insulation help reduce drafts?

Absolutely. One of the biggest advantages of dense-pack cellulose insulation is its ability to reduce unwanted air movement inside wall cavities. This helps eliminate drafts and creates more consistent indoor temperatures throughout the home.

Can dense-pack insulation lower my energy bills?

Yes. By reducing air infiltration and improving your home's thermal performance, dense-pack insulation can significantly reduce heating and cooling losses. Many homeowners notice improved comfort along with lower monthly energy costs after insulating previously uninsulated exterior walls.

Why does Rock & Tait use cellulose instead of fiberglass?

Rock & Tait recommends premium cellulose because it has a higher density than fiberglass, allowing it to better resist air movement and improve overall thermal performance. Cellulose is also manufactured from recycled paper treated with borate fire retardants, making it resistant to fire, pests, moisture, and mold.
