Spray foam insulation can keep your house warm and cozy, and lower your electric bills. But in most cases it’s not a do-it-yourself job.

It takes a qualified contractor to properly prepare and apply the foam insulation, both for safety and to ensure the best results.

Here’s some guidance from the Spray Foam Coalition on what to expect from a spray foam insulation contract and while they are on the job.

  • Installation time varies depending on the size of the job and the ease of access to the site. A small amount of SPF applied to a home’s interior can take as little as an hour or two to complete. Small spaces can typically be completed in a day once any prep work is done.
  • While the foam can be sprayed and completed in a matter of hours, people and pets need to remain out of the home for the amount of time recommended by the SPF manufacturer. CT Retrofit foam insulation contractor will limit access to the site to just workers wearing the proper protective equipment.
  • There are a number of variables that affect how long it takes for SPF to cure, including temperature, humidity levels and the SPF’s formula. Homeowners should discuss with their contractor the amount of time they need to wait before re-entering the home.
  • CT Retrofit contractor’s will turn of all gas valves etc. in the area where SPF is being applied, as well as in neighboring rooms and behind walls, such as pilot lights used in natural gas stoves or ovens, furnaces, water heaters and clothes dryers.
  • With proper installation and mechanical ventilation, foam insulation is not odorous after it has been applied and allowed time to cure. If a homeowner is concerned about odors that they think may be related to the Commercial installation, they should contact their contractor.
  • The contractor cleans the work site thoroughly before the homeowners and their pets, children and other service providers re-enter the space.

Can I retrofit my home with spray foam insulation?

All spray foam insulations starts as a liquid that instantly expands to fill between the studs in a wall cavity or ceiling joists. Most of these expanding foam insulations, like air sealing or attic insulation by CT Retrofit Foam Insulation Company must be installed in an open cavity. Because of that, you can’t re-insulate existing walls with these products unless you are doing a complete renovation and opening the walls or ceilings.

But you can still retrofit your home with spray foam insulation in a couple of different ways:

Insulate your crawlspace

Create a conditioned or closed crawlspace by adding spray foam insulation to the walls and adding mechanical ventilation. This seals and insulates the crawlspace, which helps keep the temperatures more moderate in the area. Many times this can help reduce drafts and cold floors in the interior of the home because the living space is now on top of a semi-conditioned space.

Seal off a vented crawlspace by adding spray foam insulation to the crawlspace ceiling. The insulation is applied in direct contact with the underside of the sub floor, not to the walls. This essentially seals the crawlspace from home which can reduce drafts and cold floors in the interior of the home.

Insulate your attic

Create a conditioned or closed attic by adding spray foam insulation to the underside of the roof deck and the rafters and removing vents in the attic. This seals and insulates the attic, which helps keep the temperatures more moderate, usually only about a 10-15 degree temperature difference from the inside of the home. Having a semi-conditioned space over your conditioned space will improve the overall comfort in your living spaces, and if your ducts run through the attic, it will increase the efficiency of your HVAC unit.

Seal off an unconditioned or vented attic by adding spray foam insulation between the joists in the attic floors and an ignition or thermal barrier to meet your local building codes. This also would involve removing the existing insulation in the attic. As with a vented crawlspace, this seals the attic off from the rest of the home to help prevent air leaks and increase the comfort of your home.

Seal your HVAC ducts

You can seal your HVAC ducts with spray foam insulation to prevent unconditioned air from the attic or crawlspace from leaking into the ducts and conditioned air from escaping through holes in your ducts. This can improve the efficiency of your HVAC unit and increase the comfort of your home.

We Answer Your Insulation FAQ

Find immediate answers to your questions with these home and building insulation FAQs.

Q: What type of insulation do I need?

A: The type of insulation you need depends on where it will be installed, what R-values are required, and your budget.The U.S. Department of Energy recommends different R-values for different zones. In Florida, a homeowner can get away with using R30 in their attic, whereas the same home in Rhode Island would require higher levels of insulation or a higher R-value.

Q: What is loose-fill fiberglass?

A: Loose-fill fiberglass insulation is typically blown into unfinished attics, nonconforming spaces and hard-to-reach areas, as this effectively fills all the nooks and crannies of the framing bay. Loose-fill, also known as blown-in insulation, provides better performance than batts because it is much less likely to leave any gaps.

Q: What is an R-value?

A: “R” stands for resistance to heat flow. The higher the R-value, the greater the insulating power and in turn, your energy savings. As mentioned previously, determining the R-value for your residence depends greatly on where it will be installed, and your budget.

Q: Are there rebates or other incentives available for insulation projects?

A: Yes! Government agencies, utilities, and others offer a variety of tax credits and other incentives to support energy-saving upgrades.

Q: Can insulation help increase my home’s property value?

A: Yes! Adding insulation to your attic can generate a return on investment should you ever decide to sell your home. This project may also reduce your heating and cooling costs by up to 30 percent and make you eligible for a federal tax credit.

Q: How can we find an insulation contractor?

A: The best course of action is to contact Rhode Island Retrofit. When you call, you will be greeted by a member of our friendly staff who will assist you with your energy efficiency project, and help you investigate and receive any applicable insulation rebates.

Air Sealing

While it’s well-known that homes require insulation to mitigate heat loss through walls, ceilings and floors, the concept of air sealing is often less understood.

Air leaks occur when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings. In addition to wasting energy, air leaks may contribute to moisture problems, and poor indoor air quality.

Air sealing will save you money on heating and cooling costs, improve system longevity, and increase occupant comfort. It will also help to create a healthier indoor environment. Air sealing doesn’t require much effort, and is generally very cost-productive.

Air Sealing Measures

Some measures you can do yourself include In RI:

Caulking around windows and doors
Installing foam gaskets behind outlet and switch plates
Installing weatherstripping around windows and doors (include the garage door)
Replacing door bottoms (thresholds) with those that feature pliable gaskets
Other sources of air leaks, such as attic and lighting fixture penetrations, are best addressed by a professional. Before beginning any of these measures, it is a good idea to have a comprehensive energy audit performed, which includes both a visual inspection and thermal imaging scan. An energy audit can detect cold spots, air leaks and intrusion, energy-hogging appliances, and insufficient insulation levels.

Save with Energy Upgrade Rebates

Good news! There are several energy upgrade rebates available that make air sealing substantially more affordable. Eligible homeowners can recoup a large sum of their project costs. Call Rhode Island Retrofit at 401.217.4055 or visit us online at

Reasons Why You Should Insulate An Old Home

There are many reasons why you should insulate an old house. A lot of houses before the 1960s do not have any kind of insulation. The reason is that energy costs were so low that people didn’t think they needed to save money on heating and cooling their house.

If you enjoy your house and want to feel more comfortable in the different seasons of the year then this is one of the best reasons to insulate your old house. An old house can be very cold and drafty in the winter and very hot and overbearing in the summer. The idea of being comfortable during the seasons gives you peace of mind knowing you will get full enjoyment from one season to the next.

To keep your house warm you need to stop the air from flowing out of your house. You can do this by adding insulation with a good “R” value. The R value represents the thickness of your insulation. Purchasing insulation with more thickness is going to keep more and more air from leaving the house.

The same with summertime do you notice how hot your attic is. The hot air has accumulated there because of the rising air. By keeping your attic cooler your whole house is going to stay cooler with the proper cooling system. Installing insulation in the walls of the old house will keep you much more comfortable in all seasons.

Another good reason to insulate your old house is to save you money on your energy costs. Keeping air from moving into and out of your house saves you money. In the summer you save by having insulation because this barrier blocks out any air coming through the walls, attic and other areas of the house. Having insulation keeps the temperature in your house at a more constant level. You therefore spend less money having the air conditioner not coming on as much leading to a savings in your utility costs.

People with old houses before 1960 didn’t have to worry about the changing energy costs that happened more in the Seventies. Today if you want to save money with your old house you’re going to need some insulation. There is just too much air going through your walls. Installing some installation is going to keep the exchange of inside and outside air to a minimum.

Another good reason to insulate your old house is to reduce the noise level that is coming from the outside. More peace and quiet while you are in your home can be a great reason to start adding some insulation. Adding insulation doesn’t mean tearing down your old inside walls, unless you’re changing the layout of the home. There is a way of adding the insulation from the outside of the house.

Making sure your old house has insulation in the attic. This is a great place to start since this is where the majority of the air escapes or comes into the house. Keeping up on your old home’s insulation can save you money and make you much more comfortable.
