Spray Foam Insulation

Spray Foam Insulation is a form of insulating that creates a seamless air barrier instantly upon application. Expanding instantly, Spray Foam fills into every nook and cavity, leaving no holes, cracks, or seams for outside air to get in or inside air to escape out. With a higher R-Value than traditional fiberglass or blown-in cellulose insulations, Spray Foam Insulation will never settle, sag, or shrink. All of Isenberg Spray foam material is environmentally friendly and contains no harmful or hazardous chemicals. Spray Foam Insulation is the state of the art when it comes to insulation technology.

Closed Cell Insulation

Identifiable by its yellow color and rigid surface, Closed Cell Insulation provides a High R Value (R - 6.7 per Inch) as well as a greater resistance to the leakage of air and water vapor. Closed Cell Insulation provides excellent moisture and vapor barrier for applications below grade or in moisture and vapor rich environments. Closed Cell Insulation also provides significant additional structural strength.

Open Cell Insulation

Identifiable by its light green color and soft surface, Open Cell Insulation provides an excellent R Value (R - 4.2 per Inch) at a great cost. Open Cell Insulation provides a seamless air barrier which also acts as a sound barrier, reducing outside noise up to 75%.

Thermal Barrier Coatings

DC 315 is interior ignition or thermal barrier coating for spray polyurethane foam insulation. Depending on your particular application, an ignition or a thermal barrier are required by Building Code. DC 315 is water based latex system that dries quickly and reaches maximum properties in less than 14 days.

DC 315 over polyurethane foam to prevent surface ignition due to a flame source. This product will inhibit or prevent the start and spread of flame encountered on the surface and is designed to be a long term protective barrier.

DC 315 is a coating specifically formulated for application over spray foam insulation. DC 315 will inhibit or prevent the start and spread of flame. The coating can be used as an ignition barrier or thermal barrier depending on the thickness installed over the foam.

DC 315 complies with ICC-ES AC 377 Appendix X (Modified NFPA 286) concerning fire protection and spray foam insulation. As of Jan 1, 2011 ALL brands of spray foam must meet the criteria of Appendix X to meet building Code.

FIRESHELL® (F10E) is a proprietary non-flammable, intumescing interior coating that provides oxygen starvation to fire. It is a non-toxic, water based, drain safe, no fuming GREEN product.

FIRESHELL® passes full scale room corner over foam NFPA 286 and E84 class A certified. It is a water based one part coating system that comes white but is available in a variety of different colors.


Spray Foam Frequently Asked Questions

Where can spray foam insulation be applied.

We apply spray foam insulation on attics, roof deckings, basement band boards, exterior walls, barns, garages, pole barns, foundations, cellars, crawl spaces and much more! Ask us how we can help you with a free consultation and estimate.

Do I have to do any prep work before having Spray Foam applied?

No - The only prep work Isenberg Spray Foam needs is clearing anything out of the way that could interfere with application or that you didn't want to get dusty.

Can you spray directly on metal?

Yes - Isenberg Spray Foam Insulation bonds instantly to any surface, including metal, wood, drywall, plastic, brick, or concrete. The ONLY thing we can't spray is water!

How long will my application take?

95% of all of our applications are done in one business day. Many are completed in a matter of hours.

Will I have to leave my home for the application?

Absolutely not. In applications like basements, crawl spaces, and attics, you won't even know we're there. There may be a slight smell while we're spraying but it usually clears as soon as we stop.

Can you inject foam into my existing walls?

No - Unfortunately at this time we cannot inject into existing walls. The Spray Foam expands too quickly and would blow out the drywall.

Top 5 Reasons to use Spray Foam Insulation


The secret to a energy-efficiency is simple...keep the outside air out, and the inside air in. Unfortunately, air can travel through even the smallest cracks, holes, or seams. Even with traditional fiberglass insulation, air easily passes through the spaces between the wall studs and the insulation batts, reducing the effective R-Value of the assembly. Isenberg Spray Foam Insulation has no seams or cracks because it immediately expands to fill every nook and cranny. And because Isenberg Spray Foam Insulation doesn't shrink, settle, or sag over time, the air seal advantage continues to provide energy savings year after year.


The same Isenberg Spray Foam air seal that prevents air from flowing in and out works equally hard at preventing outdoor pollutants such as smog and pollen from penetrating your home - not to mention pests and rodents. And because Isenberg Spray Foam Insulation creates a seamless moisture barrier, it inhibits the growth of mold and bacteria. All that adds up to a safer, healthier home for you and your family.


There are obvious long-term benefits that come from having a more energy-efficient home, including reduced energy consumption and reliance on fossil fuels. In addition, the added structural integrity that Isenberg Spray Foam provides will result in a longer lasting home and won't require insulation upgrades, which create debris for landfills. Plus, the application of Isenberg Spray Foam is a cleaner process than other insulation materials, meaning a smaller mess, less waste, and no resulting depletion of the ozone layer.


Not only does Isenberg Spray Foam Insulation create a barrier to keep air out, it also keeps noise out, thanks to millions of semi-rigid cells that absorb sound waves originating from outside your home. Isenberg Spray Foam Insulation is proven to decrease exterior noise by up to 20 decibels. Because our perception of noise levels doubles every 10 decibels, Isenberg Spray Foam Insulation has the potential to make your home up to 75% quieter.


When Isenberg Spray Foam Insulation is sprayed into the stud wall cavity of a home, its two liquid components become chemically bonded, creating a rigid plastic-like material that ties the studs and the exterior sheathing together as one. In technical terms, this is called a monolithic wall barrier, because there are no gaps or voids - only one single uniform structure. That structure actually strengthens the framing of you house, providing added protection against the elements and increasing the longevity of your home.
