"They showed up on time. They swiftly installed the insulation. I inspected the work and made one suggestion, which they promptly addressed. They cleaned the work area of stray insulation when they were finished,, and then they were gone. All in all, they were a very professional team."

"They did an excellent job, and it looks and feels great.  Alvaro did a very good job of explaining all options and prices.
The house looks fabulous, and it holds the inside temperature better due to the insulation.
The clean up was very good.

"Glenn really knows his stuff. These are great people to do business with. While we were waiting for Glen to get back to us with a quote (which only took a day) I was expecting a much highr price for foam insulation than reality. I was pleasently suprised with the pricing of foam from Foresite. If you are considering foam for your project, I highly recomend it and Foresite to do the job. If I ever have an insulation project again, I would not consider batt insulation over foam. It completly seals the whole cavity and provides a much greater R value than the "old" Batt insulation method. I only wish I had discovered foam insul. sooner!"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.

Also known as sound-dampening blankets, acoustic blankets reduce echo in a room. They come in different thicknesses and materials, and they can be nailed or glued to walls.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.
