"the insulation they recommended saved me about 5000kw a year. the amount of money i am saving is far more the insulation payment on my Eversource bill. No money cost to me out of pocket and my electric bill dropped quite a bit. best move i ever did."

"All went really well. Prior to the appointment, I was sent reading material which was helpful and prepared me for the appointment. On the day of the appointment, Nick was professional and personable. His presentation was outstanding. I really liked the videos. I had several questions, and I felt like Nick took his time to ensure I understood and was satisfied with each answer. My neighbors had their attic sprayed by Foamco and they’re extremely satisfied. According to them, their house is much more comfortable during the winter and summer, and they’re saving money monthly on energy bills. The only reason I didn’t get it done was because of sticker shock."

"Ecofoam insulated my attic with closed-cell spray foam and the results came out great. The space feels completely sealed and much more comfortable already. Sevi and the team were very professional, easy to work with, and kept me updated throughout the whole process. I would highly recommend EcoFoam for anyone looking for quality insulation work."

"We could not be more pleased with the work performed by Koala Insulation of the Sound Shore. From start to finish, the team was incredibly professional, detail-oriented, and went above and beyond our expectations. The work was done carefully and thoroughly, and everything was explained clearly along the way. Paul and Brian, in particular, were exceptionally patient and knowledgeable, taking the time to answer all of our questions and making sure we felt comfortable with every decision. The results were immediate—our home is noticeably more comfortable, and we’re already looking forward to significantly lower energy bills. If you’re considering insulation work, I highly recommend this company. Excellent craftsmanship, outstanding customer service, and a job very well done."

Insulation questions, answered by experts

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process. 

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.
