Product/Extreme longevity:


​LiteZone® has a superior proprietary film suspension system.
LiteZone® has a proprietary system for suspending films within its glass units that has important advantages over other film suspension systems. Its most important features are:
  • Applies forces to make the film taut biaxially;
  • Only applies very gentle forces to the film in order to minimize stress and thereby preserve the life of the film;
  • Allows the film to effortlessly expand or contract with temperature changes;
  • Distributes forces evenly along the perimeter of the film to avoid point loads that can cause distortions;
  • Results in a flat film free of distortions throughout the range of temperatures it will experience;
  • Allows air within the glass unit to travel between partitions so all the cavities within the glass unit are always pressure equalized.
Because the film uses UV inhibitors and is under very little stress, it will not discolour and will have a life of more than a century.

The film suspension system has been designed to work within LiteZone’s® proprietary fiberglass spacer in such a manner that more films or fewer films can easily be incorporated into a glass unit and thereby enables the scalability of LiteZone® glass units.

The LiteZone® film suspension system is an important technical advantage over competing products and is a key factor that enables a LiteZone® glass unit to be lightweight, cost effective, highly energy efficient, scalable and to have an expected life of more than 60 years.
