Standing Seam Framing System Tongue and Groove Framing System

Standing seam systems include battens which snap over the upraised legs of the two adjoining panels. This assembly is secured to the substrate by clips, typically made of aluminum or stainless steel. The most sophisticated clips are made in two pieces such that the upper portion can "travel" with the panel during expansion and the lower portion will remain fixed to the substrate. These are called "articulated clips."

allow for panels to be installed from either the inside or the outside of the building.

Advantages of Polycarbonate Over Glass:

The benefits of choosing a polycarbonate system over a glass system include:

  • High-quality diffused daylight
  • No interior or exterior shading devices needed (if certain options are chosen)
  • Light weight, high strength, requires less structure
  • Reduced field labor costs
  • Faster installation
  • Curves easily in field (cold forms) to suit the design
  • Cuts easily for unique shapes
  • Lower U-value (higher R-value)
  • Color options for exceptional aesthetics
  • 100 percent recyclable material contributes to LEED points
  • Greater impact resistance
  • Available in long lengths... eliminates leak-prone joint
Advantages of Polycarbonate Instead of Fiberglass Reinforced Polyester (FRP) Systems:

* No settling for one-size-fits all–total flexibility
* Greater light transmission possible
* Long lengths (up to 39 ft) with fewer joints, eliminate leakage
* Exceptional flexibility for interior and exterior designs
* Superior smoke and flame generation characteristics
* No potential for fiber “blooming” or delamination
* Field curving possible (cold curving)
* More modern appearance
