These durable, low-maintenance panels are interlocked and mechanically field-seamed in place, yielding a single membrane allowing for quick construction and strength at a lower cost. The slotted clip allows up to 3 1/4" of thermal movement. SSR's patented ridge system seams together and provides a true expansion joint. Panels are available in either 22 or 24 gauge zinc aluminum coated steel with 3"-high ribs. Available in 6 colors plus base Galvalume.

And VP’s patented bull-nosed ridge cap is part of the overall roofing envelope to ensure a complete weathertight seal. Using a unique clip system that allows plenty opf thermal movement, these 24” wide panels with a 3” high trapezoidal profile are produced in lengths from 10’ to 45’. Roof slopes range from ¼:12 up to 4:12

    Insulation Systems

    Thermal Block: Minimizing heat escape where insulation is compressed over purlins or joists is one of the best ways to improve the thermal efficiency of a building. Better thermal efficiency means lower energy costs and lower life-cycle costs.  VP's Thermal Block provides an economical way to improve thermal performance by reducing heat escape at contact areas over roof secondary. When thermal blocks are used along with 6" rolled fiberglass insulation, there is an improvement of 25% compared to systems where thermal blocks are not used. 

    VP’s SuperBlock system for SSR and HWR is capable of delivering an ASTM-C236 Hot Box tested, in-place R-value of 22.8 with a non-reflective facing. If using a reflective facing, the R-value can be as high as 23.5.VP's unique Seamed Ridge system for SSR and HWR allows for a consistent look and efficient closure and protection at the apex of the roof.
