Standing Seam Metal Roof Solar Reflectance

Interlock standing seam metal roof panels are a fully interlocking system.

Standing seam metal roof solar reflectance.

Solar reflectance index calculated according to astm e 1980. Incorporating advancements in coating technology the energy performance characteristics of metal sales finishes and colors meet demonstrated requirements established by energy star and the cool roof rating council crrc for solar reflectance and thermal emittance for steep sloped and or low sloped buildings. Recycled content of berridge metal. Initial minimum solar reflectance of 0 65 and 3 year aged minimum solar reflectance of 0 50.

Low slope roofs require an initial sr value of 0 65 or higher and 0 50 or greater after three year. Berridge metal products have a high recycled content and are 100 recyclable at the end of their lifespan. With a conventional roof such as asphalt shingles you would need to drill holes into the roof in order to mount the panels. 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.

Metal roofing color availability chart for kynar 500 or hylar 5000 pre finished galvalume steel and aluminum for metal roofing curtainwall storefront. The sr value is a number from 0 to 1 0. Initial minimum solar reflectance of 0 25 and 3 year aged minimum solar reflectance of 0 15. For low slope applications 2 12 or less pitch.

Energy star requires an initial sr value of 0 25 or higher for steep slope 2 12 roofs and 0 15 or greater after three years. Cool metal roofing systems help reduce the energy need of air conditioned buildings and makes unconditioned buildings more comfortable. Its unique mechanical lock design profile forms a weather tight unit and unlike some other types of panel metal roofs no rivets or screws are exposed on the surface of the panels. Many cool metal roofing systems are also energy star certified and may qualify for tax incentives.

Standing seam systems are frequently made with cool roofing coil that have highly reflective pigments and highly emissive metal. The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing. Colonial seam continuous standing seam metal roof panel with an integral seam. Clipless one piece positive locking standing seam panel that provides a timeless roof appearance.

For steep slope applications greater than 2 12 pitch. Our standing seam is also available in tapered and curved designs. Standing seam is great for mounting of the pv solar panels no need to drill any holes in the roof as pv panels are mounted onto the seams of the metal roof with the help of s 5 brackets. Pac 150 90 single lock.

This means these systems do an excellent job of reflecting the sun s rays and dispelling the associated radiant heat that other roofing types may retain. This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof.
