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.

Weather Roof

Fasteners: Concealed fastening system. The clips are available as floating or fixed. Two different clip heights are available to allow for thermal blocks.
