Sun Tunnel Sun Pipe

Sun Pipe Flat Roof

Sun Tunnels

Sun tunnels are designed to bring natural daylight into areas that might not benefit from windows.

Sun Pipes collect daylight from domes placed on top of the roof and reflects it down a highly reflective super silver finished aluminium tube through a diffuser located at ceiling level which distributes the light evenly within the room. Producing a brightly lit space below reducing potential energy costs and improving the health and well-being of individuals.

  • Maximise the penetration of natural daylight with a 4mm thick high impact resistant acrylic dome designed to capture daylight from morning to early evening sun.

  • 2. Flashing Plate

  • Varies with sun tunnel type however acts as flashing plate for roof installation and is designed to suit a variety of tile and roof finishes.

  • 3. 610mm Extension Pipe

  • 0.5mm Thick anodised aluminium pipe with a Miro silver 27/427OAG finish which maximises light reflections and minimises limit diffusion. Crimped edges allow easy installation to the dome and additional tunnels eliminating light leakage from potential gaps formed.

  • 4. Adjustable Elbow Angle

  • The adjustable elbow is coated in the same Miro silver as the extension pipe however allows the sun tunnel to achieve different routes and angles while limiting the light loss from the elbow angle.

  • 5. 250mm Extension

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

  • 6. Plywood backing plate/template

  • uAllows installer to 'mark out' the opening at ceiling level and to provide additional structural fixing for the diffuser.

  • 7. 250mm Extension Tube

  • 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.
