Monodraught Flat Roof Sun Tunnel Kit
The SUNPIPE natural daylight sun tunnel for flat roof directs sunlight into a room from roof level. The SUNPIPE collects daylight using a patented Diamond dome, using a silverised PVD coated mirror-finished aluminium tube to transfer light to a room, with a ceiling diffuser evenly distributing the light around the room. SUNPIPES are suited to almost any application, and have been installed anywhere from residential bedrooms to the Olympic Handball Arena in London.
All sunpipe systems are guaranteed for 10 years

Specification


1. Acrylic Diamond Dome
As Standard we use high impact acrylic in our patented Diamond domes which maximises the penetration of natural daylight.

2. Galvanised Flashing Plate and ABS Collar
Galvanised Flashing plate manufactured from 0.8mm galvanized mild steel which is corrosion resistant and suitable for felt, membrane and asphalt roof finishes. Supplied with an ABS (acrylonitrile-butadiene styrene) collar for dome to fit on to.

3. 610 Plain End Pipe
The 610mm plain end pipe is manufactured from 0.5mm thick anodized aluminium pipe and is coated with MIRO SILVER® 27/427OAG to maximise reflections and limit light diffusion.

4. Plywood Backing Plate/Template
The 4mm thick plywood backing plate/template can be used to 'mark out' the opening at ceiling level and to provide additional structural fixing for the diffuser.

5. 250 Ceiling Extension
The 250mm ceiling extension is manufactured from 0.5mm thick anodized aluminium pipe and is coated with MIRO SILVER® 27/427OAG to maximise reflections and limit light diffusion. This provides a permanent joint between the diffuser and plain end pipe.

6. Double Glazed MicroPrism Ceiling Diffuser
The double glazed microprism diffuser is designed to offer excellent thermal performance whilst ensuring maximum spread of natural daylight within the space and an even light distribution. The trim is supplied in white as standard. 230mm Sunlumes are provided with a 3-piece polycarbonate diffuser.
