Do Sun Lite Tunnels come with a guarantee?

Keylite Sun Lite tubular roof lights have been designed and developed under ISO 9001 quality management systems. The Sun Lite glazing is manufactured from 3mm clear UV-stabilised polycarbonate. This has a 10-year warranty (supported by the polycarbonate manufacturer) against loss of impact strength, excessive yellowing and loss of light transmission.

The production process has also been assessed by the polycarbonate manufacturer and the warranty has been extended to cover any effects of the forming process. The glazing and flashings have been impact-tested to EN 1873 Modular Roof lights and may be deemed to be non-fragile for HSG33 Safety in Roof work. Tubes and elbows have 25-year product warranty, which guarantees that the material will not splinter, yellow, darken, peel off, blister, reflectivity, even after prolonged UV exposure.
