Weather Roof III (WRIII)
Product Description
A metal standing seam roofing product attached to sub-framing using a variety of concealed, interlocking clips that provide for minimum panel penetrations. This panel can be used on new construction as well as retro-fit on existing structures. This panel design provides a high degree of weather tightness and has been tested by independent laboratories in accordance with ASTM E283 and E331 (for air infiltration, water penetration, and wind uplift).
Gauge: 24 and 22 (by special request only)
Finishes: Galvalume and Architectural Series
Lengths: 50′ maximum is standard but longer lengths available by special request.
Fasteners: Concealed fastening system. The clips are available as floating or fixed. Two different clip heights are available to allow for thermal blocks.
Manufactured: Houston, Caryville, Mattoon, Rome, Salt Lake City and Atwater
Usage: New and retro fit applications.
