Signet Sunpipe

Piping sunlight was first used about 4000 years ago when the Egyptians used light shafts and mirrors to bring daylight down to the centre of the Pyramids. The modern version of light pipes was introduced in 1988 and our partner Monodraught recognized the enormous energy saving potential of SUNPIPE® natural daylight systems to all kinds of commercial, Industrial & Public places / properties.

The SUNPIPE natural daylight system directs sunlight into a room from roof level. The SUNPIPE collects daylight using a Diamond dome, with a silverised PVD coated, mirror-finished aluminium tube to transfer light to the room, which is then evenly distributed in the room using a ceiling diffuser. SUNPIPES are suited to almost any application, and have been installed everywhere from residential bedrooms, Plants & Warehouses, to Commercial Establishments & even the Olympic Handball Arena in London.
