Insulation is efficient when it has a higher R-value, referring to the ability of insulation to resist heat traveling through it in either direction. If you want to enjoy the highest possible level of heat resistance, then spray foam insulation is what you want caressing the walls of your home. Developed in the late 1970s, this type of insulation has become a popular choice for homeowners due to its unique properties. Made of a combination of two chemicals that blend together to form a foam, spray foam insulation can be used in new residential constructions or retro-fitted into your walls to replace older or less-efficient insulation. We’ll help you make confident decisions right for your budget and home insulation needs.


Make a wise investment that will be good for your bottom line by choosing spray foam insulation to keep your interior spaces comfortable for your employees, visitors, and customers. In addition to providing maximum efficiency, this type of insulation can reduce sound transfer to create quieter work areas. Our experienced contractors can install commercial spray foam insulation in any business, retail, or publicly used space, including schools, churches, warehouses, and similar structures. You’re sure to appreciate the durability of a product that can pay for itself over time when you factor in potential long-term savings from the increased efficiency you’ll enjoy.

CT Retrofit spray foam insulation expands up to a hundred times its original volume. This expansion seals your home creating energy savings by preventing air leakage.

Is Spray Foam Insulation Safe?

We have years of experience insulating homes in CT. It is safe and eco-friendly as well as it can be soundproofing and water resistant. Spray foam insulation is used in basements, under porches, walls and ceilings. All spray foams must be installed by certified installers to ensure proper application and safety for everyone at the work site.

How Does Spray Foam Insulation Work?

It starts to expand as soon as it hits oxygen. It starts to fill in all the cracks, crevices, and all the hard to reach places. When properly applied by a certified spray foam installer, the spray foam will expand many times its original size. When it expands, it creates an airtight barrier preventing air leakage or infiltration. This dramatic expansion is what makes spray foam great for new construction and existing homes and commercial buildings in Connecticut.

What Are The Benefits Of Using Spray Foam Insulation?

There are many benefits associated with spray foam insulation. Because of spray foams expanding and hardening properties, it almost doubles the strength of the walls where its applied. At the same time, the spray foam works like a glue to hold roof sheathing in place. This is especially important in areas that have high winds.

Deters Mold

Spray foam is not only water resistant, but it is composed of an inert polymer that provides no source of food for mold or bacteria. Homes that are insulated using closed-cell insulation are better protected against mold and mildew.

Long Life-Span

The inert polymer that spray foam insulation is comprised of allows it to have an indefinite lifespan. This allows homes and businesses to enjoy the benefits of spray foam insulation for years on end before needing to re-insulate. Businesses and families that invest in spray foam insulation can actually save money over the course of 20 years or more because of spray foam’s unique ability to perform at optimal levels for extended periods of time.

Can Spray Foam Save Me Money In The Summer And Winter?

Yes it can! Let’s face it, if you live or work in Connecticut or any other state around it, you know New England winter weather can be very cold. And summers can get pretty hot. One if the largest benefits of using spray foam insulation is that it saves you money! Insulating with spray foam helps seal your home and prevent your warm or cool air from leaking out.

Save money in the summer You will save money on air conditioning and electricity bills in the summertime by keeping your home cooler and more efficient. And in cold north east winters, your home will retain its heat better and save you money on heating expenses. Without spray foam insulation, many homes in CT will have up to half of their warm and cool air leak outside. That is the same as throwing their hard earned money out the window. Let Connecticut Retrofit help you save money and improve the quality of your biggest investment, your home.

Spray Foam insulation is the best combatant of heat loss and air infiltration than any other insulation material including fiberglass and cellulose.
