"Brad and his team did a superb job installing spray foam insulation in our home in southern NH. Brad has a great understanding of how buildings work. The foam his team installed made our home incredibly and immediately warmer for a very fair price. He was upfront and very well reasoned about what would and would NOT work for our ice dams and cathedral ceilings.. His company scheduled us and completed the job faster than all the other contractors offered to do. He also offered a better price out of four bids. I feel that we really were lucky to have chosen Brad to do the work. We received four bids, some were substantially more expensive. And yet, Brad offered the only solution that made sense to us and that actually WORKED. The install went very fast. 24 hours post installation, we had zero smell. Our home was left as clean as when they started the work. I am extremely impressed."

"I scheduled a time with Brian Gordon to come give me a quote and he arrived promptly on time. His quote for vacuuming out the old spray insulation and blowing in new cellulose insulation into my attic was a very fair price. He and his team did a great job. I would recommend him to anyone."

"Roland did an excellent job. He explained the things I needed and those that I didn't. He was right on time and finished the job in the time he stated. He was very professional and knew what he was doing. If you are looking for a straight shooter without any of the sales frills (and the larger cost) then Sav-On Insulation should be your choice."

Insulation questions, answered by experts

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

Yes! Outdoor faucet covers work by enclosing the faucet with a thick, insulating material that will keep the faucet warmer than outdoor temperatures. They need to be sealed tightly against the house to work properly, though, so be sure to tighten the rubber strap or drawstring on the insulation cover to best protect your faucets.

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.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.
