Spray Foam Insulation St. Louis
Spray Foam is a two-part product that is heated and then is sent through a hose into the stud cavity, where it hardens in a matter of seconds and creates a long-term barrier that keeps your home comfortable and energy efficient.

Blown In Attic Insulation St. Louis
Consisting of small pieces of insulation, this type of insulation can quite literally fill every nook and cranny of a space and create an uber-fluffy layer of effective insulation. Our technicians ensure your attic, wall and ceiling cavities are filled correctly and without gaps or voids.

Insulation Removal Services St. Louis
If you’re experiencing moisture damage, pests, mold, diminishing efficiency, or other problems, we’ll remove existing insulation, and sanitize and deodorize the areas.

Batt Insulation Installation St. Louis
One of the most recognizable forms of insulation. Batt comes in large rolls or pre-cut sections that are typically pink or yellow in color. These are installed in sheet form and laid out between the studs in walls, floors, and attics.

Solar Attic Fans St. Louis
Solar attic fans turn your attic into a livable space by pushing hot air out and pulling cool air in. Our fans use solar energy to keep your attic at a comfortable temperature year-round.

Air Sealing Service St. Louis
We identify and seal leaks letting air in and out of your home to reduce unwanted temperature loss or gain.

Services Offered
Koala Insulation offers the following services for residential homeowners.
- Blown-In Insulation: Tiny pieces of insulation made from fiberglass, cellulose, mineral wool, and denim fill cavities in your attic, ceiling, and walls, cushioning your home from outside air and eliminating small gaps.
- Spray Foam Insulation: We insert foam via a hose into the stud cavity, allowing it to harden and provide a long-term barricade against outside air. This solution helps strengthen walls and reduce noise.
- Batt Insulation: Made from fiberglass, organic cotton, or mineral wool, batt insulation is one of the most common forms of insulation. It comes in sheets, which we install between studs in your attic, floor, or walls.
- Air Sealing: Over time, many homes develop leaks around doorways, windows, chimneys, wiring holes, and attic hatches. Our sealant solution fills in the leaks, helping to keep outside air from entering your home.
- Solar Attic Fans: A solar attic fan runs entirely on solar energy and helps keep your attic cool during summer’s hottest months.
- Insulation Removal: We can remove wall, crawl space, and attic insulation damaged by excess moisture, age, and pests, then sanitize and deodorize the area.
- Crawl Space Services: Our team can investigate and repair leaks in your crawl space insulation.
- Builder Services: We partner with builders and renovation teams to insulate your property.
Poor Insulation Causes
Abnormally high energy bills, uncomfortable room temperatures, and mold indicate the need for an insulation refresh. A few potential causes of poor insulation include:
- Age: Old insulation deteriorates over time. Unfortunately, there isn’t much you can do to stop it. Once you notice home temperature differences, it’s likely time for new insulation.
- Damaged Insulation: Contaminants like dirt, bugs, and moisture can damage your insulation, causing gaps and cracks that slowly worsen.
- Electrical Stress: An electrical failure, like overvoltage, can structurally damage insulation.
While you can’t protect your home from all the causes of poor insulation, you can take action quickly to prevent it from further deterioration.
