Services
Open Cell Spray Foam
Open cell spray foam insulation offers cost-effective R-value efficiency at 3.8 per inch. This eco-friendly solution provides superior sound dampening (STC 38) and creates an effective air seal when applied at greater thicknesses. Ideal for attics and wall cavities, it outperforms fiberglass while maintaining environmental sustainability through reduced energy consumption.
Closed Cell Spray Foam
Closed cell spray foam delivers R-7 per inch with built-in vapor barrier properties. This high-performance insulation strengthens building structures while preventing air and moisture infiltration. Perfect for commercial coolers, residential foundations, and energy retrofit projects, it reduces energy loss by up to 50% while maintaining formaldehyde-free composition.
Cellulose Insulation
Made from 100% recycled newsprint, cellulose insulation combines environmental responsibility with exceptional thermal performance. Dense-packed applications (3.5#/cu ft) create air-tight seals in walls and attics while offering superior fire resistance. This formaldehyde-free solution provides year-round temperature control and noise reduction for residential and commercial buildings.
Mineral Wool Insulation
Mineral wool insulation uses volcanic rock and slag to create a 100% recyclable, fire-resistant barrier. With inherent moisture resistance and formaldehyde-free composition, it provides continuous exterior insulation sheathing. Ideal for energy-efficient new construction and retrofit projects, this VOC-free solution maintains thermal performance without compromising environmental standards.
Fiberglass Installation
Fiberglass batts offer cost-effective insulation for garages and outbuildings when combined with eco-friendly solutions. While less energy-efficient than spray foam, this familiar material meets specific building code requirements. Our team integrates fiberglass with air-sealing measures to optimize performance while maintaining budget-friendly installation costs.

Report
The Green Cocoon was recommended to us by our energy consultant 6 years ago when we began remodeling our 1950's house into a net-zero home powered by solar. After vetting other insulation service companies, we settled on the Green Cocoon to foam in the entire house creating an energy-saving envelope. Their work was impeccable, highly professional, with absolutely no issues, and we have had no electric or other utility bills to pay over the last 5 years. I recommend them for your consideration, they worked for us.

The Green Cocoon Team was great to deal with! From scheduling, being flexible to work on weekends, to the installation team; it was a good closed cell insulation experience. Would recommend them for your next job.

The Green Cocoon came two separate times to complete my job, spray foam and blown in cellulose. Both times, the guys were prompt, professional and did a fabulous job from start to finish. They went over the job with me upon arrival and did a walk through at completion. The one aspect of their work that I was most impressed with is how well they cleaned up at the end of the job.

We hired The Green Cocoon for air sealing and blow in cellulose in our 500 sq foot attic. They did a nice job and their service was responsive and professional throughout. Chris returned my call and got us a quote within a day. They were busy and had a month wait, but Joe was upfront about the scheduling and even squeezed us in a little earlier than promised. Anthony and team arrived on time, easily solved a couple of minor problems (lighting, venting), showed me the work when complete and left no trace in the house. I'd recommend them!

3rd time using The Green CoCoon and very satisfied. Their crews are very professional, do excellent work and leave the site clean. They always check in and make certain we are satisfied before leaving. Our latest job was finishing the main roof of our house. We previously had them do the roof on a "bonus room" / extension and when finishing the current work, they made sure to seal / tie-into the bonus room roof making sure there were no gaps. Highly recommend them
