Standing Seam Metal Roof Solar Reflectance

Reflectance in relation to metal roofing refers to uv and infrared light rays being reflected from the roof surface.

Standing seam metal roof solar reflectance.

Pac 150 180 double lock. Interlock standing seam metal roof panels are a fully interlocking system. A highly reflective and highly emissive painted or granular coated metal roof is optimal for reducing energy consumption and can actually re emit up to 90 of absorbed solar radiation. You can attach an s 5 solar panel holding brackets to the raised seams of a standing seam roof.

Recycled content of berridge metal. Pac 150 90 single lock. A cool metal roof with high solar reflectance and high thermal emittance would have a lower surface temperature as compared to a roof with low reflectance and low emittance. Pac 150 180 double lock.

Low gloss low sheen 70 pvdf finish. Berridge metal products have a high recycled content and are 100 recyclable at the end of their lifespan. In the case of a cool metal roof a lower surface temperature translates into less heat gain into the attic space or living space below the roof. Architectural metal roofing panels metal wall panels and related products such as soffit panels highest quality fascia and coping systems.

Solar reflectance index calculated according to astm e 1980. Clipless one piece positive locking standing seam panel that provides a timeless roof appearance. Metal roofing color availability chart for kynar 500 or hylar 5000 pre finished galvalume steel and aluminum for metal roofing curtainwall storefront. Pac 150 90 single lock.

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 deduction applies to roofs installed between january 1 2011 and december 31 2020. The sr value is a number from 0 to 1 0. The only exception is a standing seam metal 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. 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. A value of 0 indicates that the material absorbs all solar energy and a value of 1 0 indicates total reflectance. Colonial seam continuous standing seam metal roof panel with an integral seam.

However crystalline panels are bulkier and use a special mounting system which requires roof penetrations.
