Spray Foam Insulation FAQ

If you’re new to learning about insulation, we expect you have plenty of questions. Foam Connection is happy to answer any of your insulation questions over the phone or in person. You may also browse our most frequently asked questions and answers below.

Spray foam insulation is an insulation and air barrier material that seals walls, floors and ceiling cavities against air movement, including spaces around electrical outlets and light fixtures and where walls meet windows and doors. Spray foam insulation can provide an effective air barrier insulation to minimize air infiltration through walls and ceilings, preventing drafts, cold spots and energy loss. The performance of spray foam insulation means that humid indoor/outdoor air is restricted from entering the walls & ceilings and condensing, thereby minimizing the possibility of moisture entrapment & build-up within the wall & ceiling cavities. This is conducive to preventing building envelope failure due to moisture damage.

For builders, spray foam insulation can reduce construction time by simplifying the insulation process and minimizing the number of callbacks due to building envelope failure as a result of air borne moisture entrapment and buildup within the cavities. With spray foam insulation, heating and cooling costs are typically reduced by up to 50% and smaller, less expensive heating and cooling equipment can be used because of the reduced heating and cooling loads. For homeowners, spray foam insulation offers the opportunity of lower heating and cooling costs from reduced air infiltration and a more comfortable home, draft free without cold spots. Furthermore, spray foam’s continuous air barrier capability will significantly reduce unwanted airborne noise from the outside resulting in a quieter interior living space. Proper mechanical ventilation must be provided to spray foam insulated houses and when merged with an air-to-air heat exchanger like HRV or ERV, superior air quality can be achieved for a healthier indoor environment.

Foam Connection spray foam products do not contain environmentally harmful blowing agents like HFCs, HCFCs or HFAs, in fact most spray foam insulation products are 100% water-blown making them better for the environment. Organic chemical compounds from petroleum extract are the main source of its ingredients.

Spray foam insulation products do not offer any food value; therefore do not support bacterial or fungal growth. Furthermore, it also does not retain water, making it an unappealing environment for fungal spores.

Spray foam seals tiny cracks and penetrations that would otherwise allow unwanted airborne irritants to invade the living space. Home occupants are protected from outdoor allergens, pollutants, and humidity. Spray foam makes it easy to get a tight fit around wall openings, such as windows, electrical/cable service entry points, and light fixtures. Spray foam makes it an even healthier option for homeowners and is recommended for spaces occupied by people with allergies, asthma and other particular respiratory issues.

Most of the damaging moisture within a building envelope is the result of air movement through the cavities. When warm air meets a cold surface within a cavity, it condenses; and if not found in time, it can lead to mold and rot. Spray foam creates continuously insulated, tight walls and ceilings – exactly the leak-free building envelope that is needed to minimize the potential for moisture, condensation and mold. Spray foam has been tested and proven not to be a food source for mold.

As an effective air-seal, spray foam eliminates the air gaps through which airborne sound travels. As a result, spray foam is able to noticeably control mid-range frequencies noise, which includes the most common sounds, the human voice and stereo music.

The initial investment of spray foam insulation is higher than that of batt or blown insulation. However, the benefits of spray foam far exceed any other insulation choice today. In fact, you will find that spray foam insulation gives you a much higher return on investment by saving between 30-50% on your annual energy costs. Spray foam insulation will help your heating and air conditioning system to work more efficiently. Since spray foam insulation helps regulate your temperature throughout your entire home or building, your HVAC temperature will not drop or rise dramatically every time it’s turned on/off. Your initial investment in spray foam insulation pays you back over time in energy savings.

We DON’T recommend a DIY spray foam installation for a variety of reasons. While many DIY projects offer cost-cutting incentives, spray foam installation requires extensive experience as well as protective gear to avoid hazards. Since spray foam expands very quickly and sticks to anything, it needs to be applied in a timely, efficient and expert manner. Too much or too little spray foam in any given area can create immediate and future problems. Spray foam exudes chemicals, which can be harmful at close proximity. Ultimately, most home and business owners are not sufficiently trained to install spray foam, and are very happy to call upon us for their insulation needs.

Spray foam insulation should be installed by fully trained, licensed professionals who spray the solution into open building envelope such as studded walls, ceilings and floors. Proper job preparation and clean up are the most important parts of the process and should be properly executed using industry best practices.   Foam Connection only employs “documented” licensed professionals that have been trained to adhere to our industry leading installation process.

Definitely. Foam Connection can install open cell and closed cell spray foam into hard-to-access spaces. We inject the foam as a liquid and then it rises to fill and insulate the space. We have found that injection foam can be a cost effective solution to many retrofit insulation installations.

Spray foam expands up to 100 times its original volume within 4-10 seconds. Independent studies indicate that with 24 hours’ active ventilation after spraying is completed. 

YES, Foam Connection is one of the only companies in the industry that can accommodate next-day service.  Give us a call!
