Sunpipe - Natural Daylight Systems - Specification

SUNPIPE® Natural Systems

Description

This system maximises the concept of renewable energy by reflecting and intensifying sunlight and even normal daylight, down through a pure silver base mirror-finish aluminium tube.

A clear UV stabilised polycarbonate top dome seals the light pipe against the ingress of dust and a clear stipple finish or plain opal diffuser at ceiling level evenly spreads light into the room or space below. The SUNPIPE system is highly effective in both sunny and overcast conditions and even when it is raining.

There is virtually no limit to the length of SUNPIPE natural daylight system or the number of bends that can be used and the SUNPIPE carries a 10 year guarantee.

Composition

The SUNPIPE consists of a high purity silver coated aluminium tube, which has a 10 year guarantee against discolouration.

This specular aluminium surface is coated with PVD and the presence of a UV inhibitor provides outstanding QUV durability with no decrease in total reflectance and the special surface treatment provides excellent colour rendition of natural light.

A brushed nylon gasket at the top of the system allows the system to breathe preventing condensation problems, whilst the diffuser at ceiling level seals against the ceiling. All vertical joints are sealed with aluminium tape.

Top Domes

Top Domes are available in UV stabilized polycarbonate as standard or are supplied in impact resistant modified acrylic, where SUNPIPE systems are to be used in a harsh UV prone environment such as the Middle East. The Diamond domes are injection moulded polycarbonate or acrylic 4mm thick.
