SPS membranes are strong, flexible sheets composed predominately of synthetic polymer manufactured to strict quality control requirements. Advantages of pre-fabricated sheets include the consistency of the quality of the membrane and accessories, and versatility in their attachment methods that may be used on a variety of commercial building applications.

SPS provides maximum freedom of choice in roof design, performance and appearance to suit new construction and refurbishment. In addition to providing a durable and watertight membrane roofing system, many SPS sheets are furnished from the factory with a highly-reflective “cool roof” surface that becomes part of an energy efficient building envelope system. Cool roof systems reflect rays of the sun, reducing building cooling costs.
