Topglass® GC Ultra-Safe


Where there is a possibility of FRP translucent fiberglass roofing sheets posing a danger to foot traffic on the roof or a possibility of not being able to install safety netting under the FRP translucent fiberglass roofing sheets, I-Cons Asia had jointly developed a heavy duty and high impact roof lighting system to alleviate these concerns. Aptly named Topglass GC Ultra-Safe, the product utillses a heavy duty, woven roving reinforcing system positioned within the resin matrix, thereby providing exceptional strength. This made Topglass GC Ultra-Safe trafficable after meeting the impact strength tests of
AS 4256.3 clause 11.3, AS 4040.4:1996

  • Trafficable FRP where safety wire mesh below FRP is not abailable

  • Meets impact strength requirement specified by AS/NZS 4040.4 ;1995

  • Climatex Gel Coating 100 microns coating thickness life time non-fibre surfacing

  • Ultimate UV Absorber by UVAS+ new generation nano ultra-violet absorber
  • 30 Years warranty

Key Benefits

Whilst Topglass GC Ultra-Safe is classified as heavy duty, meets the impact test of AS 4040, satisfying the reequirements of AS 4256.3, and can support foot traffic, long term degradation and or post roof installation impact damage can seriously affect the performance of the sheeting. In order to comply with the requirements of AS 1562.3:2006 Part 3 Plastic, protect the weather surface coating and provide continual structural strength, all FRP products should be protected from foot traffic, therefore a suitable proprietary aluminium walkway is always recommended
