A growing number of sports venues, airports and cultural facilities are choosing conventional ETFE materials for their roofs and facades to create an open, outdoor atmosphere in a controlled, conditioned environment. ETFE’s minimal mechanical strength and thermal performance has often led to multiple layers of material with extensive fritting and close-spaced structural elements and cable reinforcing, which obstruct the transparency envisioned by designers and owners of their facilities.
The vastly superior strength of ViewScape allows for longer spans with fewer secondary support elements and no reinforcing cables, reducing both visual clutter and installation time and costs for the roof system. Designers can also opt for a single layer of ViewScape where an inflated, multi-layer cushion system would be required with conventional ETFE.
ViewScape is the first transparent film that far out-performs traditional ETFE in both strength and solar control. With ViewScape, a composite rooting system with built-in solar control, designer can get the best of both worlds: the clarity of ETFE with the strength and solar properties of conventional translucent building materials.
The greatly improved solar performance of ViewScape allows a transparent roof to provide needed thermal protection without multiple cushion layers and no fritting. The material can be seen through making it more aesthetically pleasing than any ETFE.
