Causes of Poor Insulation
Many homes use the same insulation for years, if not decades. However, no insulation lasts forever — even if it's made from top-quality materials. Some of the reasons why insulation may lose its effectiveness:
- Climate: Homes in locations with extreme temperature variations may require more frequent insulation replacement. Humidity can also damage insulation, causing it to become damp or wet over time.
- Age: Insulation deteriorates over time. If yours is over 15–20 years old, it may need to be replaced.
- Materials: Insulation made from fibreglass or organic materials degrades faster than insulation made from other materials.
- Contaminants: Insects, moisture, dirt, and other contaminants can make their way into insulation through cracks in your walls or attic, damaging insulation fibers.
- Electrical Stresses: Electrical events such as lightning strikes or power outages harm the structural integrity of insulation.
Services Offered
Koala Insulation provides quality insulation services to restore your home's comfort. If you're unsure which one is right for your property, consult with our experienced team members for tailored advice.
- Blown-in Insulation: This type of insulation is suitable for enclosed spaces and difficult-to-reach areas, such as attics. It consists of loose-fill cellulose or fiberglass materials that are blown in to cover the space. Blown-in insulation minimizes outdoor and indoor noise and offers a quick installation.
- Spray Foam Insulation: Areas prone to drafts can benefit from spray foam insulation. It covers air leaks and gaps with a special sealant that prevents energy from escaping. Spray foam can last decades and is very resistant to mold and mildew.
- Batt Insulation: Made from fiberglass or mineral wool, Batt insulation is a reliable solution for insulating walls, ceilings, and floors. It comes in rolls, which are pre-cut to fit between studs and beams.
- Insulation Removal: Our team carefully removes old, defective insulation to make way for new materials. Afterward, we fully clean and disinfect the area.
- Air Sealing: We use thermal imaging to locate air leaks throughout your home. Once they are found, we apply a sealant to close the gaps and eliminate drafts.
- Crawl Space Services: Our crawl space insulation and encapsulation services create a sealed barrier to prevent moisture buildup and air leaks.
- Solar Attic Fans: A fan improves attic air circulation and prevents upstairs heat traps. It also reduces humidity and prevents moisture buildup within attic insulation.
- Commercial Services: We work with property owners and developers to install high-performance insulation in commercial buildings.

From start to finish, Chris and the team were great to deal with! They were thorough, friendly, prompt and tidy! Chris gave us more than a fair deal. I hope my home wouldn't need further insulation servicing anytime soon but if we do, we will definitely come back to Koala!
