Tubular Skylight

Dark Stairway


Have you always been a little
frustrated that the stairway
or other location in your
home is not lighted as well
as it should be.

The tubular tunnel skylight is
the alternative to flipping a
light switch each time you
go down the stairs or any
other dark area in the home.

The tubular skylight will
illuminate up to 100 square feet
and once installed provides free
light.

This a great way to go green.

The tubular skylight is water
tight, any snow on the roof
does not have to be removed
around it.

Pitched Rigid Sun
Tunnel Skylight


The skylight is a perfect solution
for rooms such as bathrooms,
kitchens, walk-in-closets and halls.

Tunnel Skylights bring bright
white daylight into small spaces
and rooms where other types of
skylights will not fit.

The complete installation does
not take a lot of time and only
few tools are required.

This is the easiest type of
skylight to install, only a round
hole for the tube is required
in the roof and ceiling.

No cutting of rafters is required.

Tubular Skylights Installation


The tubular skylight is light,
and weather proof.

The skylight kit consists of
reflective tubing, ceiling ring,
diffuser and a sunlight
collecting dome.

Check that all parts are in the
box. Note the kit comes with a
10-inch and a 14-inch circle
template.

Pay attention that you use the
correct template when cutting
the holes.

The templates look alike, but
the 14-inch template is a bit
longer.

There is no roof boot sealant with
this kit, so you have to buy it
separate.

Pick a cooler day to work in the
attic, as it gets quite warm up
there.

Working on a roof can be dangerous,
pick good weather with no wind or
rain.
To avoid slippery asphalt shingles,
choose a dry day.

It may also be necessary to use a
safety rope and harness on steeper
roofs.

ODL tubular skylights will fit roofs
with a roof pitch between 3:12
and 12:12.
Roof pitch, is how far the roof drops
vertically for every 12 inches of
horizontal run.

The straighter the tube is vertically,
the better the results, this places
the dome directly above the
ceiling diffuser.

The more the dome is in the
sunlight, the brighter the light
at the diffuser.

Pick a spot on the roof where it
picks up the most sunshine.

Survey the attic area for the
desired location. It should be
free of wires, plumbing, roof
valleys and anything that might
prevent the install.

Clear the area of insulation and
drive a small 2 inch nail between
the ceiling joists in the
approximate location.

Run a plumb line from the nail to
the roof, mark the center for the
roof hole.

Drive a nail up through the roof,
or drill a hole and poke a piece of
stiff wire such as a straightened
out clothes hanger wire through
the hole.

On the roof, this is easy to find
and is the center for the roof hole.

Go down into the room where
the diffuser will be installed,
and find the nail protruding out
of the ceiling.

Use this nail as a center guide.

Draw the circle using the
template and using a saw, cut
the hole.

Up on the roof, find the wire
poking out.

Use the circle guide to draw the
circle on the shingles.




To use the template, slip the one
end over a nail and on the other
end, place a pencil and draw a
complete circle.

Use the shorter whole length of
the template strip for the ceiling
and the longer, for the roof.
Drill a 3/8 inch hole into the
roof plywood to start the blade
of a reciprocating saber saw
and then cut through the
shingles and plywood.

On the roof, use a flat bar to
break the shingle seal above
the cut.

Remove any nails in the way.

The flashing of the tunnel skylight
will slip into place by laying it
flat on the roof and by gently
sliding it uphill into place.

When you are sure, the fit is
good, remove the roof flashing
and apply a roof sealant
completely around the hole on
the bottom of the flashing.

Insert the flashing back into
place and secure the flashing
with the 2-inch screws and
washers.

Cover any exposed nail heads
with sealant.

Back in the room, turn the flip
tabs of the ceiling ring inward
and place the trim ring up into
the hole in the ceiling.

Reach through the hole and turn
the flip tabs out, this will hold
the ceiling ring in place, do not
over tighten.

Back on the roof, measure the
length of the tubing that is
needed.

Measure the distance from the
top of the roof flashing
(longest side) to the ceiling.

There is an upper section and
a lower section of tubing in
the kit, choose the smaller
tube as the lower section.

The larger pipe flange, will not
fit into the ceiling ring properly.

Use tin snips to cut the tubing
to length.

Drop the cut tubing through the
hole in the roof flashing with
the flanged edge of the tubing
on the lower side, then press
gently downward until you feel
it click into place, in the ceiling
ring.

Place the top tube dome onto
the roof flashing.
Spin the dome until the letter N
on the dome faces north.

Press down snugly and secure
the dome with the short screws
provided along with the rubber
washers, in the kit.

Drill 1/32 inch pilot holes.
Do not over tighten.

Back in the room, install the
glass diffuser assembly to
the ceiling ring.

To install, align the diffuser
with the three tabs on the
trim ring and turn clockwise
until snug.

Installation is Complete!


History of Skylights


The earlier skylights were built in
such a way that they could be to
be opened.

Manual devices were incorporated
to open and close the unit.

One had to keep an eye on the
weather when the skylight was
opened.

These earlier skylights often
leaked.

Later versions of the opening
version were much improved
because of better materials,
design and sealing.

Roof skylights started in Europe
after world war two.

Tubular skylights were invented
in 1986 by Steve Sutton, an
Australian.

Tubular skylights were introduced
to the US in 1992.
