Sun tunnel

VELUX sun tunnels are complete instal-

lation kits delivered with all necessary

components for both exterior and interior

connections. An installation kit consists of

three modules:

• Exterior rooight module

• Tunnel (exible or rigid)

• Interior light diuser unit

The sun tunnel directs the natural light

into areas of the house where installa-

tion of traditional VELUX roof windows is

either not possible or not appropriate. It is

recommended for corridors, storage rooms,

toilets etc.

The sun tunnel is available in two sizes, 010

(Ø 250 mm/10”) and 014 (Ø 350 mm/14”).

Installation of a sun tunnel requires access

to the attic. This does not apply to TCF that

is designed for ﬂat roofs with a roof thick-

ness between 200 and 900 mm.

ROOFLIGHT MODULE

The choice of rooﬂight module depends on

roof pitch and rooﬁng material:

- TCF for ﬂat roofs, roof pitch 0°-15°. Made

of environmentally friendly PVC, with poly-

carbonate dome

- TLF/TLR for ﬂat rooﬁng materials such as

slates, roof pitch 15°-60°. 4 mm toughened

glass pane with clear and clean coating

and integral ﬂashing made of lacquered

aluminium

- TWF/TWR for proﬁled rooﬁng materi-

als, roof pitch 15°-60°. 4 mm toughened

glass pane with clear and clean coating and

integral ﬂashing made of polyurethane
