Expert Attic & Home Insulation Solutions Contractor

How much is your attic costing you every month?

Did you know that nearly 70% of homes are under-insulated? That means your home insulation isn’t performing as it should, resulting in higher utility bills. Under-insulation causes your HVAC system works overtime to maintain temperature, moisture problems you won’t see unless you’re inspecting your attic regularly, and ice dams that damage your roof in winter.

Most homeowners don’t realize their insulation is inadequate until they’re dealing with ice dams or sky-high energy bills, but we can assess your attic during a roof inspection and solve the problem before it costs you thousands. We treat attic insulation and ventilation as an integrated system—proper R-values balanced with airflow to maintain consistent temperatures, prevent moisture buildup, and protect both your roof structure and living space.

Spray Foam Insulation

This insulation is sprayed into place and expands to fill cavities, creating an excellent air seal. It can be either open-cell or closed-cell, with closed-cell being denser and more rigid.

Fiberglass Insulation

Often made of fine glass fibers, this is a very common and inexpensive type available as batts, rolls, or loose-fill insulation. It is good at reducing heat and sound flow.

Cellulose Insulation

Typically made from recycled materials like newsprint, cellulose is a popular eco-friendly choice. It can be installed as loose-fill or blown-in insulation and is effective in attics and walls.

Mineral Wool

These are boards made from foam that resist conductive heat flow and are often used in areas like crawl spaces and unfinished walls.

Rigid Foam Board

These are boards made from foam that resist conductive heat flow and are often used in areas like crawl spaces and unfinished walls.

Radiant Barriers

Reflective insulation systems that are particularly useful in hot, sunny climates to reflect radiant heat away from the home.

Home Insulation FAQ

You should replace old insulation to improve energy efficiency, reduce high energy bills, and enhance indoor air quality. Old or damaged insulation can cause uncomfortable drafts, inconsistent temperatures, and can harbor pests, mold, or moisture.
To choose insulation, first determine the recommended R-value for the area of your home and your climate zone, then choose a type of insulation that fits your project, budget, and installation method. The higher the R-value, the better it resists heat flow, which is more important in colder climates and for areas like the attic. Popular types include fiberglass batts for DIY projects and blown-in cellulose or spray foam for retrofitting walls, while factors like moisture resistance and cost also influence your decision.
R-value in insulation measures how well a material resists the flow of heat, with a higher R-value indicating greater thermal resistance. It is a key factor in energy efficiency, as better insulation with a higher R-value keeps your home warmer in winter and cooler in summer, which can lower heating and cooling costs. While R-value is the most common term, you may also see it referred to as “resistance value” or “RSI-value” when using SI units

The R-value insulation you need depends on your climate zone and the part of the house you are insulating. In colder climates, you need higher R-values for all areas, with attics typically requiring R-49 to R-60, exterior walls needing R-13 to R-21 (depending on wall depth), and floors needing R-25 to R-30. You can find the specific recommendations for your region by checking local building codes or the U.S. Department of Energy’s climate zone map

Yes, insulation reduces noise by absorbing sound waves and preventing them from traveling through walls, floors, and ceilings. Different types of insulation have varying acoustic properties, and thicker or denser materials are more effective at blocking noise.
Spray foam insulation can last for several decades, with the lifespan varying by type: closed-cell foam can last 80-100 years, while open-cell foam typically lasts 30-50 years. The longevity also depends heavily on proper, professional installation, as well as protection from extreme conditions like excessive moisture, UV radiation, and heat, which can accelerate degradation over time.
You should primarily insulate your attic first, as heat rises and can escape through the roof. Other key areas include exterior walls and the crawl space or basement, as these are major sources of heat loss and cold air entry. Floors over unheated spaces, like garages or porches, and foundation walls should also be insulated to prevent drafts and cold floors.
You can save up to 20% on your energy costs by adding insulation and sealing air leaks, which can translate to up to 10% savings on your total energy bill. The exact amount depends on factors like your climate, the current insulation level, and the type of insulation used.

South Central Wisconsin Roofing was a local company known to us. The Owens Corning system they use is the best we saw and it has a Fifty Year, transferable warranty. They also were the best price on replacing our roof. Many said they couldn't start for some time; South Central started a week after receiving our deposit. Their crew showed up on time and wasted no time. Old roof was off, new roof on and all cleaned up in one day. Overall outstanding; price, product, labor and importantly, people. We recommend them, period.
