White Tpo Roof Solar Reflectance

Install the ultraply tpo roofing system in accordance with current firestone ultraply tpo specifications details and.

White tpo roof solar reflectance.

The roof has never been cleaned as can be seen by the dirt under the panels. Peak advantage guarantee information product guarantee term jm tpo 60 mil 5 10 15 or 20 years codes and approvals. Aged 85 tan initial 81 3 yr. Firestone ultraply tpo is a flexible thermoplastic polyolefin roofing membrane that is produced with polyester weft.

This membrane is ideal for commercial projects or diy projects such as sunrooms carports breezeways porches etc. Initial 3 year white tan gray solar reflectance 0 79 0 69 0 61 0 55 0 34 0 34 thermal emittance. But where the membrane is fully exposed rain has kept the membrane white and reflective. White initial 95 3 yr.

Gaf analyzed membrane samples from roofs across the us and studied thickness over scrim surface cracking and the ability to repair aging tpo membranes. Citation needed a roof made of white thermoplastic for example can reflect 80 percent or more of the sun s rays and emit at least 70 of the solar radiation that the roof absorbs. White thermoplastic membrane roofs pvc and tpo are inherently reflective achieving some of the highest reflectance and emittance measurements of which roofing materials are capable. Tile roofs can be made of clay slate or concrete.

Roofkit 10 by 100 foot white tpo reinforced membrane is 45 mil thick and is for use on flat roof surfaces. Aged 75 gray initial 39 3 yr. How they can be made cool. It is defined so that a standard black reflectance 0 05 emittance 0 90 is 0 and a standard white reflectance 0 80 emittance 0 90 is 100.

A value of 0 indicates that the material absorbs all solar energy and a value of 1 0 indicates total reflectance. Tiles can be glazed to provide waterproofing or coated to provide customized colors and surface properties. Solar reflectivity r solar reflectance index sri by color. Some are naturally reflective enough to achieve cool roof standards and surface treatments can transform tiles with low solar reflectance into cool roof tiles.

Aged 37 recycled content post consumer 0 post industrial 5 the leed solar reflectance index sri is calculated per astm e1980. Solar reflectance index sri is calculated per astm e 1980. Converting from a dark to a mid reflectance roof e g. The sri is a measure of the roof s ability to reject solar heat as shown by a small temperature rise.

A recent study of everguard tpo roofs installed between 8 and 16 years ago found they all performed above astm standards for newly manufactured tpo. Clearly based on their reflectivity ease of maintenance and longevity white tpo membranes are the best choice for these applications. The membrane can be used for new roof installation or as a replacement roof.
