"On time, friendly, courteous. Explanation of the process was great. Very careful of there equipment set up and very respectful of my property. They sent me pictures of my attic afterwards. They vacuumed up all of the loose debris afterwards. Very pleased with Coldani. I would and will highly recommend Coldani Insulation. Thank you again for the excellent customer service."

"We hired ThermaCore Insulation to remove our old attic insulation, air seal the attic, and install new insulation. Kamal and his crew were professional, honest, and easy to work with from start to finish. During the inspection, they found several air leaks and duct issues that other companies completely missed. They explained everything clearly, completed the work on time, and left the area clean. We noticed a big improvement in comfort right away. Great service, fair pricing, and quality workmanship. Highly recommend ThermaCore Insulation!"

Insulation questions, answered by experts

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

There are many ways to keep your house cool without central air. In fact, ductless mini-split AC systems are a solid alternative to central AC for situations when you can’t install ducts in your home. If you’re looking for a more budget-friendly cooling solution, consider using window AC units or portable air conditioners.

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.
