What is spray foam insulation?

Spray Foam Insulation, also known as Spray Polyurethane Foam or SPF, is an insulation that is applied
as a liquid and then expands, forming the foam. SPF can be either open or closed cell in structure,
depending on the density desired. The density will depend on the specific project for which it’s being
utilized and on its intended purpose and/or desired goal. Special equipment is needed to apply the SPF
as well as many months of technical training.

SPF is considered to be one of the best building materials because of its adaptability. SPF uses are
endless, including bear caves and giant foam pumpkins to root vegetable cellars and farmers’ grain
dryers. Some of the things you can use SPF for include but are not limited to:

Residential and commercial insulation in walls, attics, ceilings, basements, crawl spaces, well lines, and
Air barriers - Extremely important piece of the energy efficiency puzzle.
Roofing - provides a long life roof system as well as insulation.
Increase structural integrity of buildings.
Sound control.
Industrial pipes, tanks, coolers, freezers.
Floatation uses, including docks, barges, boats etc.
Commercial/Industrial buildings, pole barns, metal buildings.
And the list goes on...

SPF can provide excellent solutions to many construction challenges due to its remarkable versatility.

Open cell spray foam insulation

Open cell is spray applied polyurethane foam that expands 120 x its liquid volume providing superior
insulating, air sealing and sound properties. Open cell foam utilizes water as a blowing agent trapping air
in the structure of the cells.


Real world R-value performance
Completely fills tight spots and hidden areas allowing for performance gains that would otherwise be
overlooked by other products.
Great sound reduction properties

Limitless commercial industrial and residential insulating and air sealing properties.
Sound walls
Although open cell foam has a lower R-value per inch than closed cell it will still provide great results.
Open cell foam like closed cell works on all three principles of heat transfer. This is what makes foams
superior insulators. As well as a great thermal insulator open cell will provide for excellent sound

Closed cell spray foam insulation

Closed cell foam is a spray applied polyurethane foam that expands 30 x its liquid volume. It utilizes an
inert gas blowing agent that is trapped in the cell structure of the foam allowing for an R-value of approx 7
per inch. Contains no formaldehyde and shows no levels of off gassing.

Benefits of CC

Complete air barrier
Higher R-value per inch
Increased structural integrity
Low perm rating
Moisture barrier

Limitless commercial, industrial and residential insulation and air sealing applications.

                                                           Moisture control
                                                           Coolers, freezers
                                                           Molds and plugs
21st Century Foam is committed to raising the standard of energy performance in an effort to do our part to reduce our nation's dependence on
foreign energy. To that end, we proudly represent a non-toxic spray foam insulations/air-seals*. Air-seals also have outstanding sound reduction
characteristics. Areas where the difference will quickly be appreciated include offices, classrooms, media rooms, master bedrooms, laundry
rooms. Below are brochures of a few of our products we use.
