Residential Spray Foam Contractors in Minnesota

Your Spray Foam Experts

Heating and cooling accounts for 51% of the total energy used in the average American home. If you want to substantially reduce electric bills and keep condensation problems at bay, investing in residential spray foam insulation is a good place to start.

Lange Spray Foam offers efficient and affordable spray foam insulation for homes in Minnesota.  We supply and install a range of products, from roofing insulation to closed cell spray foams, enabling us to tailor the correct solution for your property.

Spray foam acts like a flexible, air-tight barrier that effectively seals gaps and crevices better than fiberglass and cellulose. It can be sprayed onto any surface, helping regulate room temperatures, improve air quality, and provide year-round comfort and cost savings.

Reasons to Install Spray Foam Insulation

Space & Cost Savings

By using spray foam insulation, you can downsize HVAC equipment by as much as 35%. This may translate into additional floor space and lower energy costs.

Reduced Health Risks

Spray foam insulation seals leaks and crevices, helping improve indoor air quality. The seals protect against dust, germs, and airborne allergens. Spray foam also blocks water intrusion, preventing mold and mildew growth.

Superior Durability

Unlike traditional insulation, spray foam retains its effectiveness for decades. It will not sag or soften over time even in extreme temperatures.

Optimal Indoor Comfort

Spray foam enhances indoor comfort by reducing drafts, cold spots, and temperature variations.

The Installation Process

Spray foam is made by combining isocyanate and polyurethane. Once applied, the foam hardens and expands up to 100 times its liquid form.

Foam is sprayed directly into the roof, walls, basement, attic, and crawl spaces of your home. The curing period usually lasts 24 hours depending on site conditions. To avoid breathing harmful vapors, vacate your vicinity until the foam has fully hardened.

Applying spray foam requires specific skills and equipment. Incorrect installation can be expensive to fix and even pose health risks.
