Flash and Batt

“Flash and batt” is a popular technique for insulating walls but if you are going to use this technique, make sure to start with at least 2 inches of closed cell foam first.  A one inch “flash” is not enough to prevent condensation!

Where is your energy going?

Energy Consumption

The largest misconception people have regarding energy is where they believe they use and waste the most energy. Heating and cooling are the main energy consumers in buildings and account for two thirds of a building’s total energy consumption. However, most of this energy is wasted due to inadequate insulation. Insulation is the most effective way to reduce energy costs. By using well-proven energy efficiency techniques, 70 to 90% of a building’s energy need for heating or cooling can be cut.

Nominated for an Award!

Last month The Green Cocoon was nominated for an award at the National Spray Foam Convention in Palm Springs. Dozens of companies enter their projects in hopes of winning an Industry Excellence Award, but only 5 are chosen to be publicly recognized at the awards luncheon, and we were proud to be one of the five. Although we did not win, we were in the 2017 Industry Excellence awardtop 5 for Commercial Wall Spray Foam category. In an industry with thousands of companies, being voted in the top 5 for the 233 Vaughan Street Project in Portsmouth, NH is a testament to our company’s passion for excellence, honesty and drive to be the best in our industry.

Hurricane Season is Upon us!

Although the Hurricane Season in New England is defined as June 1st to November 30th, 75% of the 40 tropical systems that have impacted our region in the past century have struck during the months of August and September. The last severe hurricane to hit Massachusetts was Hurricane Bob in August 1991. Bob, a Category 2 Hurricane, with winds between 91 and 110mph, caused almost $1 billion in damage, at the time. More recently, Hurricanes Eduardo (1996), Bonnie (1998) and Bill (2009) threatened the Bay State, but veered out into the Atlantic as they traveled up the coast (www.mass.gov).

Remembering Our First Passive House

We here at the Green Cocoon have a passion for efficiency, not only in our daily operations but also in the projects that we choose to work on. We have been fortunate enough to work on everything from small renovations and existing attics to energy positive, net-zero and our favorite, the Passive House. What is a passive house, you ask? The term passive house (Passivhaus in German) refers to a rigorous, voluntary standard for energy efficiency in a building, reducing its ecological footprint. A continuous, balanced supply of fresh air ensures unparalleled indoor air quality. Operable windows connect indoors with out. Super-insulated walls hold warmth in the winter and cool in the summer. Special windows and a building envelope consisting of a highly insulated roof and floor slab as well as highly insulated exterior walls keep the desired warmth in the house – or undesirable heat out. It results in ultra-low energy buildings that require little energy for space heating or cooling.

Dan ROy passive house
Currently in the U.S. there are less than 100 certified passive houses in existence, and we have worked on 4 of them. In the fall we will be starting another passive house in Rhode Island. We like to think of ourselves as the “go-to insulation company” for highly energy efficient projects.

Our Foam Is Now Even Greener!


When it comes to reducing our carbon footprint and making our homes more efficient, the phrase “The more insulation the better” is often used.  While all insulation materials reduce greenhouse gas emissions (by saving energy and reducing our use of fossil fuels), insulating with thick layers of spray foams often results in long “payback periods” for the global warming potential of the insulation, mainly due to the most commonly used blowing agents.
