Spray polyurethane foam (SPF) is a highly innovative foam plastic that has gained immense popularity due to its unique characteristics that make it an indispensable insulator. The application of SPF involves spraying it in a paint-like form onto an open surface, where it expands to create a tight insulating barrier against wind and outside temperatures. Available in both open-cell and closed-cell varieties, SPF insulation provides a much-needed air seal to homes and buildings.

The manufacturing process of SPF involves combining two chemical substances, isocyanate and polyol resin, that react and expand to become hard – effectively creating a solid and durable barrier. Additionally, SPF insulation is highly effective in preventing moisture build-up as it pushes any air out of the way and tightly seals against walls, attics, or any other area, effectively reducing unwanted air infiltration through cracks and openings. Therefore, this innovative yet practical insulation solution is quickly becoming a preferred choice among homeowners and building contractors alike.

Open-cell foam is a highly flexible type of low-density spray foam that boasts a unique cellular structure. Being intentionally left open, this foam has the inherent ability to expand up to 120 times its original size. Consequently, it provides excellent functionality and can effectively seal buildings, enhancing their R-value. It provides air barriers that are capable of blocking outside air while preventing moisture buildup. This unique feature assists in preventing the potential damage that can result from mold and water damage. Its sound reduction properties make it perfect for use in custom built homes. Open-cell foam is generally applied to above-ground interior walls, ceilings and the underside of the roofs.

 
In contrast, closed-cell spray foam has unique properties. It features a cellular structure that is entirely encapsulated, preventing the retention of air or moisture. It is a medium to high-density foam that has a high R-value, providing better insulation in extreme temperature conditions. Unlike open-cell foam, it only expands up to 33 times its original size. It also has a more rigid texture, adding wall-racking strength and impact resistance to your property. Its built-in durability makes it ideal for use in exterior insulation, thereby providing complete air and vapor barriers. It is widely used in metal buildings, basements, roofs, tanks, freezers, vehicles, schools, brick buildings, and boats.  

The best time to have a home insulated that is occupied is October thru April. In the hot summer months, the temperature in your attic can climb well into the hundreds, which can be difficult and dangerous for the insulation crew to work in. Fall thru spring brings lower temperatures which makes for a much safer, easier work environment.

Polyurethane foam insulation is listed as a combustible insulation under the building code. The foam does have a fire retardant in it, which means it will not support flame. If you pull the source of flame from it, it will stop burning. Building code requires a thermal barrier to be put over all foam insulation (1/2″ drywall meets all thermal barrier standards).

The foam products that we use have a Class A type 1 fire rating. However, all spray foam must be separated from the living space with a fire-rated material, be it drywall or some form of intumescent coating.

Spray foam insulation is an excellent way to keep your home comfortable and energy-efficient. However, it is important to note that, like many site-applied building materials, spray foam insulation can release small amounts of chemical compounds into the air. For this reason, it is crucial that you follow all relevant safety precautions during installation to avoid putting yourself or others in danger.

It is highly recommended that you do not try to be onsite during the application of spray foam insulation unless you are wearing the appropriate protective gear. It is simply not safe for unprotected individuals to be near the foam during installation.

Typically, you should wait at least 24 hours from the time the installation is completed before you attempt to re-enter the area where the spray foam insulation was applied. During that time, the foam will continue to cure, and it may emit some odors that could be noticeable to some people.

To ensure that no one is exposed to the foam insulation before it has fully cured, it is best to vacate the area during this time. With proper ventilation, any odors should subside when the foam is completely cured, leaving you with a safe and comfortable living space.

The installation of spray foam insulation typically occurs after the rough plumbing, rough electrical, heating and air conditioning ducts and windows have been installed, but before the interior walls and ceiling are completed in the construction of a new home.

Yes, during and immediately following spray foam application. Fumes and mists are generated that can be hazardous to your health. Access to the work area during this time should be restricted to personnel wearing appropriate personal protective equipment (PPE), including respirators, and whose job responsibilities require them to be in the area.

When considering insulation options for your project, it is crucial to evaluate a few key factors to make the best decision. The type of insulation you choose will depend on various aspects such as the object or area being insulated, the primary reason for insulation, and the location of the project. By analyzing these factors, you can make an informed choice about the insulation type that will best suit your needs.

Furthermore, when deciding between open cell and closed cell insulation types, it is essential to seek expert advice. Our team of insulation professionals is knowledgeable and experienced in determining which type of insulation will be best suited for your project.

Hello! I would be happy to assist you in expanding on your message. It’s great that you’re concerned about exposure to formaldehyde from spray polyurethane foam insulation. However, it’s important to note that there is no need to worry about this issue. This is because formaldehyde is not used as an ingredient in the production of polyurethane spray foam insulation.

The concern about formaldehyde and spray foam insulation came about due to an earlier generation of foam that utilized formaldehyde in its manufacturing process. However, modern-day spray foam products are created using polyurethane foam and do not contain urea-formaldehyde. Hence, they do not have substantial levels of residual formaldehyde that one should worry about.

As you may already know, formaldehyde is a potentially dangerous chemical that can cause a variety of problems when inhaled or exposed to skin. Fortunately, modern spray foam insulation products do not contain this chemical. So rest assured that you are safe and secure when using polyurethane spray foam insulation in your home or business!

Many people are often concerned about the odor that comes with the installation of building materials like spray foam insulation. However, it is important to note that spray foam insulation is not known to have any lingering odors when correctly applied and cured.

Similar to other materials like paints, certain woods, tar, glue, and various household materials, they can often have a distinct smell during the installation process. However, these smells usually disappear within a few hours of installation with adequate ventilation. The same is true for spray foam insulation, and it is not indicative of any moldy or dusty smells commonly associated with other insulation materials.

In cases where spray foam insulation emits a smell, it is an epoxy or fishy odor that could be attributed to poor installation. These kinds of subtle odors could quickly become highly noticeable, especially in hot and humid conditions. Therefore, it is essential to ensure that installation is done professionally and adequately ventilated to prevent any equally unpleasant odors.
