Causes of Poor Insulation
Most of the time, poor insulation is unpreventable. Insulation can fail even if you keep your home in good condition and stay on top of maintenance. Here are a few primary causes of poor insulation:
- Age: The fibers of insulation deteriorate over time. Once the fibers degrade, the insulation doesn’t work as well.
- Outside Contaminants: Tiny cracks and crevices in your home’s exterior may allow pests, dirt, and moisture to enter the insulation, reducing its efficiency and speeding up the natural deterioration process.
- Electrical Stresses: Overvoltages, electrical impulses, and surges can damage the structural integrity of the insulation.
Services Offered
Koala Insulation provides comprehensive insulation services for homeowners in the Northern Illinois area.
- Blown-In Insulation: We use a wide hose to cover the cavities of attics, walls, and ceilings with Blown-In Insulation. Made from cellulose, mineral wool, denim, or fiberglass, Blown-In Insulation creates a thick, fluffy layer that fills any gaps or crevices.
- Spray Foam Insulation: This type of insulation is created from spray polyurethane foam (SPF), which hardens against walls. The thick barrier is especially good at reducing noise between rooms and minimizing temperature fluctuations.
- Batt Insulation: Our Batt Insulation comes in pre-cut rolls and sheets, which we install between the studs of your house. You can choose between fiberglass, mineral wool, or organic cotton.
- Air Sealing: A high-quality air sealant can plug holes and gaps commonly found in doors, windows, recessed lighting, attic hatches, and other areas. Air sealing further improves the efficiency of your home’s other insulation practices.
- Insulation Removal: If you need to remove old or damaged insulation before your new insulation is installed, we’ve got you covered. We remove insulation damaged by age, pests, and electrical stresses, then thoroughly clean and sanitize the area.
- Solar Attic Fans: A hot attic traps air, increasing temperatures throughout the house and potentially damaging ductwork during summer heat waves. Installing a Solar Attic Fan enhances air circulation and improves attic insulation efficiency.
- Crawl Space Services: Leaks in the crawl space can allow air and foreign contaminants to enter your home. We’ll inspect the area for leaks and install crawl space insulation where needed.
- Builder Services: We collaborate with local builders on residential, industrial, and commercial insulation projects.
