Standing Seam Metal Roof Solar Reflectance

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.

Standing seam metal roof solar reflectance.

Cool metal roofing systems help reduce the energy need of air conditioned buildings and makes unconditioned buildings more comfortable. Solar reflectance index calculated according to astm e 1980. With a conventional roof such as asphalt shingles you would need to drill holes into the roof in order to mount the panels. Metal roofing color availability chart for kynar 500 or hylar 5000 pre finished galvalume steel and aluminum for metal roofing curtainwall storefront.

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. 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. Initial minimum solar reflectance of 0 25 and 3 year aged minimum solar reflectance of 0 15. Pac 150 180 double lock.

Our standing seam is also available in tapered and curved designs. Initial minimum solar reflectance of 0 65 and 3 year aged minimum solar reflectance of 0 50. 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. The sr value is a number from 0 to 1 0.

Berridge metal products have a high recycled content and are 100 recyclable at the end of their lifespan. Interlock standing seam metal roof panels are a fully interlocking system. Clipless one piece positive locking standing seam panel that provides a timeless roof appearance. The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing.

Recycled content of berridge metal. This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof. A value of 0 indicates that the material absorbs all solar energy and a value of 1 0 indicates total reflectance. Many cool metal roofing systems are also energy star certified and may qualify for tax incentives.

For steep slope applications greater than 2 12 pitch. Low slope roofs require an initial sr value of 0 65 or higher and 0 50 or greater after three year. 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. Colonial seam continuous standing seam metal roof panel with an integral seam.

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. For low slope applications 2 12 or less pitch.
