SQUARE Sun Tunnel – Monodraught Sunpipe

The 300mm or 450mm Square sun tunnel natural daylight system is ideally suited to a normal flat ceiling, as opposed to a typical loft conversion, where a normal skylight can be used. The highly reflective aluminium light pipe reflects daylight into the room below. The light is spread evenly through the room by the recessed diffuser.
The square SUNLUME skylight tube has been specifically developed to suit standard pitched slate or tiled roof finish. The rooflight is produced in a standard 475mm by 570mm nominal size with an adaptor to to fit to the 300mm circular SUNLUME light tube. With use of our adjustable elbow, the light tube can be adjusted to fit any angle of roof pitch.
