Raytech represents a new generation of skylight system which utilizes ETFE foils.  It is a multilayered cushion type cladding system, of extraordinary features and architecture which can be used on both the roofs and walls of buildings. It has the capability of spanning large distances, without the need for steel support. This is considered one of the main and most important features in the skylight applications.

It is also characterized as light in weight, (approximately 1% of the weight of glass), and offers high insulation values (a low U value). The Raytech system can be implemented within different light patterns, by either fritting, or printing, in order to achieve the required G value, which is the light and radiation quantity allowed into the building. 

Raytech is made up of ETFE, which is short for Ethylene tetrafluoroethylene. This is an inert material with both a high transparency and translucency along with robust physical and mechanical properties as well as a life expectancy of fifty years.
