What is SPF?

Spray Polyurethane Foam (SPF) the most sustainable and cost efficient form of roofing system available today. SPF is a liquid material that expands into a rigid, closed cell foam in a matter of seconds. It increases about 30X in volume as it dries, creating an extremely durable and watertight blanket across your roof. This is the favorable roofing system for industrial and commercial buildings, and residential flat roofs.

Spray Polyurethane Foam (SPF) application

The first element is a closed cell, spray polyurethane foam insulation. Pumps are used to heat the foam and ensure that each component of the spray is proportioned. They are then mixed at the spray gun before they are applied to the roof.

The second element is the protective surfacing. This is typically sprayed but can also be applied by hand or roller. This surfaces purpose is to provide weatherproofing and to protect the foam from harmful UV exposure. It also assists with fire-proofing and damage caused from machinery.

Where is it applied?

SPF is used for flat roofing solutions for any type of roof including residential, commercial and industrial buildings.

Why is it beneficial?

With a life expectancy of 30+ years and the highest rated R-Value, it saves homeowners up to 50% on long term repairs and energy bills. Not only does SPF save you money, but its lightweight materials add structural strength and create a strong resistance to extreme weather events (snow, rain, hail, hurricanes, high winds, etc).

An R-Value is a measure used to label and rate insulation materials. R-Values are given based on two factors; how well it limits heat from escaping and the thickness of the material. The amount of insulation needed depends on your climate, type of heating and cooling system and the part of the house you plan to insulate
