SCHEDULE YOUR FREE ESTIMATE TODAYThere’s no place in Wisconsin quite like the Village of New Glarus. Known as “America’s Little Switzerland” for its rich Swiss heritage, our vibrant village is packed with charm, community, and a deep appreciation for the outdoors.

Locals take pride in celebrating traditions. Winter is filled with the Christkindli Market in December and our one-of-a-kind Silvesterchlausen New Year’s celebration (a custom found only here outside of Switzerland). In the summer, you’ll find friends and neighbors biking the Sugar River Bike Trail, fishing the ponds, or gathering for Polkafest. Our winters may be cold and windy, but that never stops the fun. From sledding in the parks, cozying up by the fire, or taking in the snowy beauty of New Glarus Woods State Park, there’s always something to enjoy.
In a community that thrives in every season, comfort at home is a must. That’s where Rockweiler Insulation comes in. As an Owens Corning® Certified Energy Expert®, we specialize in keeping homes warm in the winter, cool in the summer, and energy efficient all year round. Whether you live in a well-loved single-family home or a newly built Swiss-inspired chalet, we’ve got the solutions to make your home as comfortable as life in New Glarus is.
Tailored Insulation for New Glarus Homes
From charming Alpine-style chalets to modern single-family builds, New Glarus homes reflect a unique mix of tradition and function. With long, snowy winters and hot, humid summers, properly installed insulation is essential—no matter the home’s age or style. Rockweiler Insulation provides expert solutions to ensure year-round comfort and efficiency.
Attic Insulation & Air Sealing
The attic is one of the biggest sources of energy loss in your home. Properly insulating and sealing this space is key to a cozy home in New Glarus. Our team uses blown-in fiberglass and spray foam to seal gaps and block heat loss before it even starts.
Here’s what you can expect:
- Lower heating and cooling costs
- Fewer drafts and cold spots
- Improved indoor air quality
- Extended HVAC system lifespan
- Better protection against ice dams
It’s always the right time to seal and insulate your attic- whether you’re building new or retrofitting your current home.

Basement Box Sill Insulation
Your basement’s box sills are one of the easiest places for heat to escape. That’s because they are one of the thinnest points of your home’s exterior. Installing spray foam insulation in these areas of your Basco basement makes a big difference in your whole home’s comfort and energy use. Not only does spray foam insulate your box sills, it also seals the many air leaks around them.

Benefits include:
- Warmer floors above the basement
- Reduced heating bills
- Protection against condensation and moisture
- Added barrier against pests
Crawl Space Insulation
Being close to nature doesn’t mean inviting it into your home. The crawl space in your Blanchardville area home needs proper insulation and encapsulation to block moisture, maintain even temperatures, and prevent mold. You can count on our expert team to transform your crawl space into an energy-efficient part of your home.
We help with:
- Better temperature control in your living space
- Increased energy efficiency
- Moisture and mold prevention
- Improved indoor air quality

Garage Insulation
Your Monroe garage doesn’t have to be an icebox in winter or an oven in summer. Whether it’s your workspace, storage zone, or just where your car sleeps, insulating your garage walls and ceiling makes a difference.

Benefits of garage insulation:
- More comfortable rooms above the garage
- Protection for your vehicles and stored items
- Less energy loss from the garage
- Helps keep your car above freezing throughout the winter months
- Year-round usable space
New Construction Insulation
Building a home? There’s no better time to lock in long-term energy savings than during construction. We work closely with builders and homeowners to ensure every layer of insulation is installed correctly and efficiently. We also offer upgrades such as sound control and garage insulation for added comfort.
Why proper insulation matters:
- Immediate comfort and energy savings
- Better indoor air control from day one
- Meets or exceeds Wisconsin energy code
- Cost-effective installation

Wall Insulation
Older homes in the New Glarus and Belleville area and beyond often lack proper wall insulation, making them uncomfortable year-round. Our team specializes in retrofitting walls using dense-pack cellulose, improving efficiency without invasive remodeling. With added wall insulation you won’t be bothered when the winter temps dip below freezing and the summer temps nearly make the mercury explode.

You’ll notice the difference with:
- Lower energy costs
- Improved temperature control and better energy efficiency
- Quieter, more comfortable indoor spaces
- Less wear on your HVAC system
