Blown in insulation is a method of adding insulation to attics and wall cavities using loose insulating material that is blown into place with specialized equipment. It fills gaps and hard to reach areas more effectively than traditional batt insulation, helping improve energy efficiency and maintain consistent indoor temperatures. This type of insulation is commonly used to reduce heat loss in winter and keep buildings cooler during warmer months.
Modern Exterior provides blown-in insulation services to help improve energy efficiency and indoor comfort in homes and commercial buildings. By adding insulation to attics and other open spaces, we help reduce heat loss during Wisconsin winters and limit heat buildup during warmer months.
Proper insulation reduces the need for constant heating in the winter and cooling in the summer. It is one of the most affordable and efficient ways to improve your home's energy efficiency, providing a quick return on investment.
Increased Climate Control Capabilities
With enhanced insulation, your home will maintain a more consistent temperature, offering improved comfort throughout the year.
Superior Mold Resistance Compared to Other Insulation
Our blow-in insulation materials offer superior resistance to mold, helping to maintain a healthy indoor environment.
No Gaps or Seepage Allowed
The blow-in method ensures that there are no gaps or spaces, providing comprehensive coverage and preventing air leakage.
Can Fit Small Gaps or Tight Spaces
The flexibility of blow-in insulation allows it to fill even the smallest gaps and tightest spaces, ensuring complete insulation coverage.
Types of Blown In Insulation and Recommended Depth
Blown in insulation is commonly made from either cellulose or fiberglass. Both materials are designed to fill attic spaces evenly and help reduce heat loss. Our team evaluates your attic and insulation levels to determine the right material and depth needed to achieve the best energy efficiency for your home.
Cellulose Blown In Insulation
Cellulose insulation is made from recycled paper materials that are treated for fire and pest resistance. It is a dense material that helps limit air movement and provides strong thermal performance. This density allows it to settle tightly around attic surfaces and fill small gaps effectively.
Fiberglass Blown In Insulation
Fiberglass insulation is made from fine glass fibers and is widely used in attic spaces. It is lightweight, resistant to moisture, and provides consistent thermal protection when installed at the correct depth. Fiberglass is a reliable option for improving attic insulation and maintaining long term performance.
Recommended Insulation Depth
In Wisconsin, attic insulation should typically reach R49 or higher to meet energy efficiency recommendations. This usually requires about 16 to 20 inches of blown in insulation, depending on the material used. Our insulation specialists measure the attic and install the correct amount of insulation to reach the proper R value and ensure full coverage across the attic floor.
Our Blown In Insulation Process
1
Attic Inspection
Every project starts with a full attic inspection. We evaluate the condition of the existing insulation, measure the current R value, and look for signs of heat loss, moisture issues, or contamination from dust or rodents. If the insulation is damaged, dirty, or compacted, we may recommend removing it before installing new insulation.
2
Air Sealing and Preparation
Before adding insulation, we seal common air leak points in the attic. This includes areas around recessed lighting, plumbing stacks, ceiling penetrations, and other openings where warm air can escape. Proper air sealing helps keep heated air inside the home and plays an important role in improving energy efficiency and preventing ice dams.
3
Blown In Insulation Installation
Once the attic is prepared, we use professional equipment to blow in cellulose or fiberglass insulation across the attic floor. The insulation is applied to the recommended depth for Wisconsin, typically reaching an R value of R49 or higher. We also install depth markers throughout the attic to confirm the insulation is evenly distributed and meets the required coverage.
4
Final Inspection and Documentation
After installation, we perform a final inspection to make sure the attic is properly insulated and sealed. We clean up the attic access area and provide before and after photos so you can clearly see the work that was completed.
Related Services That Help Keep Your Home Warm
During our insulation inspection, we also look at other exterior parts of your home that could contribute to heat loss or affect the performance of your new insulation, such as areas where moisture or air leaks may occur. If we find issues with the roof, windows, gutters, or siding, we can recommend improvements that help keep your home warmer and improve overall energy efficiency.
Roofing
Modern Exterior provides roof installation, repairs, and replacements to ensure your roofing system works together with your insulation to keep your home protected from Wisconsin weather.
Old or poorly sealed windows can allow cold air to enter and warm air to escape. Installing modern, energy efficient windows helps reduce drafts, improve insulation, and maintain a more consistent indoor temperature.
A properly functioning gutter system directs water and melting snow away from your home. This helps prevent moisture buildup, roof damage, and ice related issues that can affect your home’s structure and insulation.
Siding provides an additional barrier against wind and cold temperatures. Properly installed siding helps reduce drafts, improve insulation performance, and protect the home’s exterior from the elements.
For over 17 years, Modern Exterior has provided commercial roofing services in Milwaukee. We deliver reliable flat roofing solutions, including new construction, repairs, and roof replacements, designed to perform well and last in Wisconsin’s climate.

Blown in insulation can last 20 to 30 years or longer when properly installed and kept dry. Over time it may settle or become less effective, which is why periodic attic inspections are recommended.
How do I know if my home needs more insulation?
Common signs include uneven temperatures between rooms, high heating or cooling bills, drafts, or ice dams forming on the roof during winter. An attic inspection can determine if your insulation levels are below recommended standards.
What R value is recommended in Wisconsin?
For most homes in Wisconsin, attic insulation should reach about R49 or higher. This level helps reduce heat loss during cold winters and improves overall energy efficiency.
How long does installation take?
Most blown in insulation projects can be completed in a few hours depending on the size of the attic and the amount of preparation needed.
Is blown in insulation messy?
The installation process is contained within the attic and done using specialized equipment. After the job is complete, the attic access area is cleaned and the workspace is left in good condition.
Does blown in insulation help prevent ice dams?
Yes. Proper attic insulation combined with air sealing helps prevent warm air from escaping into the attic. This reduces uneven snow melting on the roof, which is one of the main causes of ice dams.
