Spray Polyurethane Foam

What is SPF?

Spray Polyurethane Foam (SPF) Roofing is a seamless, monolithic closed cell roofing system. SPF is suitable for a wide range of new construction as well as retrofit roofing applications. Spray Foam roofing systems are unlike any other type of roof system in that they are “manufactured” in the field.

  • SPF is an insulating product preventing any lateral or vertical transmission of water.
  • SPF is monolithic; no laps, seams or joints.
  • SPF is self-flashing. It is also impervious to ultraviolet rays.
  • The SPF insulating factor is significant, an “R”- value of 6.8 per inch, thereby saving heating and cooling costs. SPF acts as an exterior thermal blanket, which shields the existing surface from solar heat and winter cold, thus reducing thermal shock and its resulting damage.
  • Compressive strength of SPF Roofing Foam is 40-50 P.S.I.

How is SPF applied?

Specialized plural-component spray guns are used for the application of the materials directly to the roof deck or existing substrate. The spray foam is applied in a continuous, seamless, self-flashing operation. It can be tapered in the field to direct water to existing drains or scuppers. This eliminates ponding water problems that plague most other roofing systems.

SPF is fully adhered with no gaps or seams which prevents any lateral movement of water in the roofing system in the event of damage, thus making leaks easy to identify and repair unlike any other roof system. After application of the SPF, a protective coating is also spray applied. Similarly, it is applied in one continuous, seamless application – sometimes in multiple coats. Depending on the type of coating being applied, roofing granules can be applied directly into the topcoat of the roof system.

Owners and facility managers looking for a roof system with the highest return on investment, increased energy savings and an indefinitely renewable roof system (through periodic re-coats) should look no further than a Cardinal SPF Roofing system.
