The Leading Spray Insulation Company in Massachusetts and Rhode Island

Spray foam insulation is a highly effective material used to create an airtight barrier in walls, ceilings, and floors. Spray foam never loses its shape, making it an ideal long-term solution. There are two variations of spray foam insulation: open cell and closed cell.

Open cell foam is soft and pliable and a great option for reducing sound noise and filling awkward crevices. It won’t crack, bend, or warp.

Closed cell foam is rigid and moisture resistant, making it an ideal choice for blocking airflow, reducing noise, and in areas that might experience water intrusion.

Our team will help determine which foam insulation is best for a property.

5C Energy Inc. is the best insulation company because of our team’s expertise and experience in the field. We provide accurate cost estimates, and our commitment to quality and customer satisfaction ensures you receive the highest level of service and the best possible results.

Day, Nick and Oscar did a great job insulating our cottage. They were timely, personable and polite. I would recommend using 5C for anything I need done in the future.
Would recommend 5C. They insulated our house quickly and we can already feel the difference. Ray was always available to answer questions and followed up promptly

I connected with Russell for a quote for attic insulation after a mold remediation. We had contracted with RISE, however, they had long waits and we had an attic with no insulation in the middle of the winter. Russell was so helpful and managed to get RISE to assign the contact to 5C within a few weeks. He kept me in the loop about the timeline and process and was always so quick to respond when I had a question. The team at 5C did a great job installing the insulation and even did additional weather stripping for us. Very thorough and helpful!

A topflight crew, descended on my 110 year old house and in a day had it fully insulated with blown in cellulose. A first class job by Manny and his crew. Thank you!
