 Twinskin Systems TS 20

Cost effective insulated double glazed natural lighting roof system


Project specifiers are increasingly becoming aware of the benefits of utilizing FGW Corporation Twinskin Systems (TS 20) when designing facilities where condensation and varying temperature fluctuations are an important factor in design considerations.

The system, first implemented in 2005 on the Invercargill velodrome complex, was well received and more recently designers have readily accepted the system as a cost effective natural lighting system offering thermal resistance and acoustic characteristics not previously available in single sheeting applications.

With rising energy costs tenants can enjoy their working environment with less heating and lighting bills than previously experienced, as the system, when utilized up to as much as 30% of roof area offers diffused lighting with shadowing almost eliminated and offering the working environment a passive interior lighting concept.

The system originally tested for thermal resistance has more recently been tested for light and heat transmission and full reports are available. Please contact us.


Key Benefits

  • Provides a cost effective insulated double glazed natural lighting roof system
  • Reduces energy costs and heat loss
  • Eliminates condensation
  • Provides good thermal properties
  • Compatible with all trapezoidal metal roofing profiles
  • Hassle free installation
  • Full independent Engineers Test Report available



For use where severe condensation maybe of concern
Or to form a thermal barrier to prevent heat loss or solar heat gain.
