What is SPF? Print E-mail
SPF is sprayed polyurethane foam, a closed cell roofing and insulation material that is rapidly gaining market share in today's construction industry.

What are the advantages of SPF?

SPF has the highest R value of any insulation material. Because it is spray applied, it forms a seamless, monolithic barrier that prevents air and water infiltration. SPF systems are referred to as "self-flashing" because they can be applied to vertical surfaces such as parapet walls and roof penetrations in a contiguous manner: thus eliminating seams and cold joints, the main source of roof leaks.

SPF roofing systems can be applied quickly and safely, without disruption to the facilities. In most reroofing applications there is no need to tear off existing membranes, offering cost and logistic advantages.

What are the disadvantages of SPF?

Though SPF roofs exist today that were applied almost 30 years ago, to many, SPF is considered new technology. As such, there are many misunderstandings concerning proper utilization of this product. As with any roofing system, it erquires a skilled craftsman and the proper materials to assure a quality application. Improper material selection, design or application has created roof failures as severe as those found with conventional roofing systems.

A Green Building Material

The application of SPF will provide better climate control within a building envelope, thereby reducing the consumption of fossil fuels and carbon emissions.
