"They installed new insulation for us in an un-insulated attic space. They were well-priced, on-time, and very easy to work with. Workers all wore protective equipment and were both professional and friendly."

"My new-to-me home built in 1947 was 95 degrees in the walk-up attic in the summer! It made downstairs hot, too. I just couldn't stand it any more. If you put your hand on the ceiling, it was amazingly hot. A friend suggested just nailing some foam boards onto the underside of the roof, but I thought there has to be a better solution. I did research, saw the blown-in insulation, and had Josh Lowe out to give me a proposal. It ended up spray foam was the better solution. Since his company installs spray foam AND blown-in cellulose, I thought he was truly telling me the better solution, rather than just selling me on one thing. Glad I chose them for spray foam, and my home is easier to live in now!"

Insulation questions, answered by experts

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Through R-value assessments based on climate and existing insulation.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

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.
