"They are the answer to lower energy costs and better comfort. In my area, home builders applied minimum standards when it came to insulation. Performance Energy fixed it and made it right. We could tell the difference overnight. Plus, they file all gov't rebates for you. Very grateful."

"Great company to work with. Came when that said they would. Very clean while working and made sure the house was kept clean,too. Did the job blowing in insulation in our attic and showed me pics of it afterward. My house, in June was crawling to 87 degrees quickly in late morning, even though we had the AC set at 72. After"

"We had a really great experience with Coastal Structural Solutions. From the beginning they were very friendly, professional, and took the time to explain everything about the crawlspace waterproofing/encapsulation so we understood exactly what was being done. They showed up when they said they would, worked hard, and did a really clean, thorough job. You can tell they care about the quality of their work and making sure the customer is happy. The whole process was smooth and stress-free. I would absolutely recommend them to anyone needing foundation or crawlspace work."

Insulation questions, answered by experts

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.
