1. What is SPF Insulation?
SPF is produced by a chemical reaction when two liquid components are combined. When the two liquids are mixed together (typically at a one-to-one ratio), a chemical reaction occurs creating rigid closed cell foam. The mixed liquid starts to react in seconds, expanding 20 to 30 times its liquid state. Once cured it solidifies and becomes polyurethane foam.

2. Will SPF insulation sag or compress over the years?
No. Spray Polyurethane Foam insulation will not sage. When applied SPF forms a ridged mass in the wall cavity that is self supporting.

3. Does SPF have to be covered?
Not in non habitable areas, it is best to check local codes. If used in habitable spaces it must be covered with drywall or comparable material to meet code. When exposed to the weather it needs to be protected from UV rays.
4. What is the R value of SPF?
Jamecel Spray Polyurethane Foam closed cell insulation is rated at a minimum of R-7 per inch.

5. How does using SPF insulation affect heating bills?
When used in new construction to seal the complete building envelope, you can save up to 50%  on your utility bills. Reddi Set Home can provide other products that will help you save.

6. Can I use spray polyurethane to insulate an existing home?
Spray polyurethane insulation is used primarily to insulate new homes. This is because spray polyurethane must be applied to an open cavity. When spray polyurethane is injected into a closed wall cavity, the pressure of the expanding insulation may damage the wall.
Consider insulating an existing home with spray polyurethane when you’re replacing the drywall, exterior siding or doing other major remodeling. Attic and crawl spaces can be done with out disturbing any of the structure.
7. When can spray foam be installed?
Spray foam insulation is professionally installed at the same point in the construction cycle as other types of insulation. That is, it should be installed after the rough plumbing, electrical wiring, and heating and air conditioning ducts have been installed, but before the interior walls are completed in new home construction. In some cases spray foam also can be applied in older homes, to the inside of roofs and under floors after construction has been completed.

8. How long has spray foam insulation been around?
For nearly two decades, this insulation has built a solid performance record in commercial and industrial applications. It has been used to fill sofa cushions and car dashboards, and its insulating properties have made it ideal for refrigerator walls, tanks, refrigerated tractor trailers, and the home building envelope.

9. Is there any off gassing from the foam?
A slight odor will be present during installation of spray polyurethane insulation. This will rapidly dissipate after the spraying operation stops. The installed spray polyurethane insulation will be odorless.

10. How does spray foam work?
A two-part mixture is applied by trained professionals to the inside surface of exterior walls, to the underside of the roof, and beneath floors in basements and crawl spaces. The spray mixture expands rapidly to fill all cracks and voids, completely and permanently adhering to wood, masonry and metal.
