"Aaron and his team got the attic insulation done on time and exceeded my expectations. He was very polite and professional in all aspects concerning this job. He did everything I asked and even gave me pictures of before and after ... I would recommend Tri-Star Wildlife to anyone ... you won't regret it. He saved me money and did more than what the other company's were asking. Mark Raith"

Insulation questions, answered by experts

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.
