The Spray Polyurethane Foam Installation Guidance is intended to provide an overview of best practices to help professional installers use SPF effectively and efficiently to insulate homes and commercial buildings. It discusses considerations for the use and handling of materials as well as steps that help make the jobsite safe and secure. It also addresses health and safety hazards and offers steps to avoid potential issues.
SPF (spray polyurethane foam) roofing systems have exceptional characteristics. They offer great insulation, are resistant to high winds, protect the substrate against damage from hail and wind driven missiles, and can be recoated to extend its life. Frequently, however, some in the roof industry have poor perceptions of how SPF roofing systems perform in hail events. For many years the conventional roofing market perceived SPF roofing as soft and easily damaged calling the system PUF.
This paper, published by the Roof Coatings Manufacturers Association (RCMA), discusses the role and impact of reflective roof coatings in mitigating peak energy demand. Developed in collaboration with Jim Hoff, TEGNOS Research Inc., this paper provides a comparative overview of base use and peak demand of electricity and shares information on how to calculate peak demand savings. The role of cool roofi ng in promoting energy effi ciency is also emphasized, particularly in respect to the unique performance properties of refl ective roof coatings. The document can also be viewed as a resource as to the benefi ts reflective roof coatings provide to buildings, businesses, and the environment at large.
Research has indicated the damage caused by wind driven missiles typically does not cause a spray polyurethane foam (SPF) roof to leak. This damage can usually be repaired economically and does not require the roof to be replaced. This document provides a means to evaluate information collected from the investigation of an SPF roof system after damage has occurred and to make recommendations for the rehabilitation and/or repair of the damaged areas.
Highest Energy Efficiency
Virtually Leak Free
Usually No Tear off Disposal
Can be Renewed Inexpensively
The performance of a spray applied polyurethane foam insulation (SPF) system for cold storage facilities can be affected by all the component parts of the building structure, as well as the atmospheric conditions inside and outside the structure.
Spray Polyurethane Foam (SPF) is a high-performance insulation that provides integral air sealing and moisture control benefits in a single product application. SPF helps seal cracks, gaps and penetrations in the building envelope in order to mitigate air leakage and deter infestation by a variety of insects, rodents, and other pests where it is applied. SPF is not known to attract nor does it provide a food source for termites; however, it can be accompanied by the use of new technologies when inspecting for termite infestations.

Spray polyurethane foam (SPF) is made on the jobsite by combining polymeric methylene-diphenyl diisocyanate (pMDI /MDI or A-side ) with an equal volume of a polyol blend (B-side ). Sides A and B react and expand at the point of application in the building envelope to form polyurethane foam. The formed-in-place SPF provides both thermal insulation and air sealing to the building.
