in your home is not
lighted as well as it
should be.

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

This a great way to go

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.

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

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

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
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

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
electrical wires, plumbing,
roof valleys and anything
that might prevent the

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

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

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

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

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

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.

Europe after world war
