Standing Seam Metal Roof Solar Reflectance

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.

Standing seam metal roof solar reflectance.

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. Solar reflectance index calculated according to astm e 1980. A value of 0 indicates that the material absorbs all solar energy and a value of 1 0 indicates total reflectance.

Clipless one piece positive locking standing seam panel that provides a timeless roof appearance. Low gloss low sheen 70 pvdf finish. The only exception is a standing seam metal roof. Pac 150 180 double lock.

Interlock standing seam metal roof panels are a fully interlocking system. The sr value is a number from 0 to 1 0. 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. Low slope roofs require an initial sr value of 0 65 or higher.

However crystalline panels are bulkier and use a special mounting system which requires roof penetrations. Tax credits energy efficiency federal tax credits homeowners can receive a tax credit of 10 of the cost up to 500 for interlock metal roofing systems installed on their principal residence. 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. Architectural metal roofing panels metal wall panels and related products such as soffit panels highest quality fascia and coping systems.

Reflectance in relation to metal roofing refers to uv and infrared light rays being reflected from the roof surface. Pac 150 90 single lock. Colonial seam continuous standing seam metal roof panel with an integral seam. 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.

Recycled content of berridge metal. Berridge metal products have a high recycled content and are 100 recyclable at the end of their lifespan. 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. Our standing seam is also available in tapered and curved designs.

The deduction applies to roofs installed between january 1 2011 and december 31 2020.
