Fixed flatlight, Opening flatlight, Flatlight roof access hatch and Sliding flatlight

TELFORM skylights offer an efficient solution to poor-illuminated rooms by sidewall windows, improving eye comfort due to zenithal light and thus reducing energy consumption. They can be made from different materials, either for the covering and frames and offer different opening devices configurations, according to requirements. 

The four skylights under study are: fixed flatlight, opening flatlight, roof access flatlight and Vital Dome S Electric Flat and are typically composed of: aluminium, plastics and rubber, glass and steel. 

The covering of FLATLIGHT skylights is made of energy-efficient flat double glazing filled with argon gas. The frames are composed of white PVC box profiles on the inside and sealed and painted aluminium on the outside. The assembly and seal between the glass and frames is guaranteed by a structural sealing.
