High Sri Tpo Roof

Reflective surfaces can deliver high solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the surface and high thermal emittance the ability to radiate absorbed or non reflected solar energy.

High sri tpo roof. Sri measures the roof s ability to reject solar heat defined such that a standard black reflectance 0 05 emittance 0 90 is 0 and a standard white reflectance 0 80 emittance 0 90 is 100. With high reflectivity and strong heat welded seams tpo is a great choice many different types of buildings. Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price. Recycled content of berridge metal.

Ultraply tpo invisiweld system the firestone ultraply tpo invisiweld system is a high performance non penetrating tpo membrane fastening system. High emissivity combined with a pigment technology that preferentially rejects infrared light allows products like timberline cool series shingles to achieve high relatively high sri values even though the shingles do not appear white to. The most well known type of reflective surface is the cool roof. In contrast to conventional roofs these kind are specifically designed to reduce internal building temperature by reflecting the sun s uv rays.

Sri is calculated with a complex formula spelled out in. Sri takes into account the entire spectrum and much of the light energy is non visible infrared light. Mechanically attached it provides high wind uplift ratings and offers simplified installation that reduces labor and material costs. Tpo is durable enough to resist punctures and flexible enough to stretch as the structure settles.

Cost wise tpo generally falls between its two main competitors being more expensive than epdm and less expensive than pvc. A tpo roof costs between 5 50 and 9 50 per square foot. The sr value is a number from 0 to 1 0. Solar reflectivity r solar reflectance index sri by color.

Sri incorporates reflectivity and emissivity properties into one easy to read standardized measure so that roof buyers won t have to scratch their heads and try to figure out if a high reflectivity and low emissivity is better or worse than a medium reflectivity and high emissivity. Tpo installation installation is important when it comes to putting a single ply roofing system on a building and there are over 140 standard tpo details available from carlisle syntec. Berridge metal products have a high recycled content and are 100 recyclable at the end of their lifespan. Reflective surfaces are a form of geoengineering.

Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope roofing system. An asphalt roof costs between 8 and 10 per square foot installed. A value of 0 indicates that the material absorbs all solar energy and a value of 1 0 indicates total reflectance.
