PARTS OF THE WINDOW

PARTS OF THE WINDOW

IF ANY OF THE PRE-PACKED ELEMENTS ARE MISSING FROM THE PACKAGE, IT MUST BE REPORTED IMMEDIATELY TO ALTATERRA CUSTOMER SUPPORT TEAM ACCORDING TO THE DELIVERY AGREEMENT. PLEASE CONTACT ALTATERRA CUSTOMER SUPPORT TEAM OR OUR HOUSEBUILDER HOTLINE FOR FURTHER INFORMATION.

Storage

The roof window stands upside down within
the packaging, so the top of the frame is flat.
On the bottom of the window there is a wooden
protection batten for wooden windows and
styrol protection for PVC windows which has
to be removed before installation.

The roof window should be stored in the
standing (vertical) position so that the corner
label on the box faces up (not upside down).

If the roof window has been taken out of
the box for any reason, it is important that
it should not been stored separately, without
packaging. Because of the position of the
pane, the roof window is not balanced and
the centre of gravity is not exactly in the middle
of the box..

ALWAYS MAKE SURE THAT THE ROOF WINDOW STANDS SECURELY.

Instalattion

WHAT TO CHECK
BEFORE INSTALLATION?

1. Roof windows should only be installed in heated, inhabited rooms. For unheated rooms like attics or garages, skylight products should be used.
2. In rooms with high levels of humidity, you should install a PVC roof window. PVC is resistant to humidity.
3. The roof pitch is important when choosing windows and flashings. Dakea products can be used in roof pitches of between 15° to 90°.
4. The type of flashing you use when installing the windows will depend on whether you’re installing one window or a combination of windows. If you’re installing a combination of windows you should use the UCX flashing.
5. The type of roofing material you’re installing into will also determine the type of flashing to be used to make sure the windows are watertight. There are three standard and two special types of flashing in the Dakea range for solo installations:

WHICH FLASHING TO CHOOSE?
KSF: FOR SLATE ROOFING MATERIALS, TAKING INTO ACCOUNT THE
OVERLAP, THE MAXIMUM TOTAL THICKNESS CAN BE 16 MM
KTF: FOR TILE OR PROFILED METAL SHEET FROM 16 TO 50 MM
PROFILE HEIGHT
KUF: FOR TILE OR PROFILED METAL SHEET FROM 16 TO 120 MM
PROFILE HEIGHT
KFP: FOR PLAIN TILED WITH A PROFILE HEIGHT OF 14MM AND
MAXIMUM LENGTH OF 340 MM
KFF: FOR SLATE ROOFING MATERIALS, CONSIDERING OVERLAPPING
THE MAXIMUM TOTAL THICKNESS CAN BE 16 MM.
KFF FLASHING ENSURES 40MM DEEPER INSTALLATION
WITH BETTER ENERGY PERFORMANCE AND AESTHETICAL
BENEFITS.

PREPARING
THE ROOF OPENING

POSITIONING THE ROOF WINDOW IN
THE ROOM

Position the roof window in the room taking into account:
• the use of the room
• whether you want a clear view when standing/seated
• comfortable operation
• optimum design of linings
• building regulation requirements

HOLE IN THE ROOF

First consult the installation instructions supplied with the
window. If there is no access to the roof from the outside,
make a hole in the roof surface by cutting a small hole,
approx. 400 × 400 mm, from the inside through the roof
construction. When battens have been cleared, the final
position of the window in the roof construction can be
determined. When measuring, be sure to allow space for
insulation around the window frame.

POSITIONING THE ROOF WINDOW

To minimise need for adjustment of the roofing material,
adjust the position of the roof window sideways, if possible.
When adjusting sideways, be sure to allow for the
recommended distance between rafter/trimmer (a).

ADJUSTING THE POSITION

ADJUSTING THE POSITION

Adjust the position of the roof window upwards/downwards
depending on the type of flashing. Always read the
installation instructions before you start. In roofs with:
• profiled roofing materials, allow for a full course of tiles
below the roof window
• slates, ensure necessary overlap between slates and
flashing
To allow for correct insulation around the frame, allow
space for 20–30 mm insulation / side and 45 mm vertically
due to the bracket geometry.

PREPARING
OPENING

HOLE IN UNDERROOF AND
INTERIOR CEILING FINISH

Roofing felt can be cut as shown and folded in
order to ensure water tightness. If the underroof
is rigid, make a hole in the underroof the same
size as the hole in the roof surface. In a roof with
an existing interior ceiling finish, it is necessary to cut
a temporary rough opening in order to install the roof
window. Project frame dimensions perpendicular
to the ceiling finish, mark and cut hole. Note that
it must be possible to connect the vapour barrier
within the existing roof construction (if present) with
the new vapour barrier around the roof window.
The final adjustments of the hole in the ceiling finish
should not be made until the lining kit or lining has
been installed.

PREPARING
ROOF WINDOW

REMOVING SASH

The sash can be removed to facilitate the installation of
the roof window. Place the sash with the top of the sash
downwards on a clean and even surface. Make sure that
gasket on top of the sash is not pressed.

INSTALLATION BRACKETS

As standard, installation brackets are supplied with the roof
window. The brackets must be fitted to the frame prior to
positioning the window in the roof.

NOTE THAT THE POSITIONING OF THE BRACKETS ON THE FRAME
DEPENDS ON THE FLASHING BEING USED.

PREPARING
ROOF WINDOW

IFC – INSULATING FOAM COLLAR

The Insulation Foam Collar forms an insulating frame
around the window and restricts heat loss. It ensures faster
and faultless installation.
The Insulation Foam Collar is pre-cut so all you have to do
is stick it on using the adhesive side.

NOTE THAT THE POSITIONING OF THE BRACKETS ON THE FRAME
DEPENDS ON THE FLASHING BEING USED.

FIXING AND ADJUSTING
THE ROOF WINDOW

FIXING AND ADJUSTING
THE ROOF WINDOW

It is important to adjust the square and level of the roof
window to ensure a weathertight seal between the sash
and frame and for optimum operation. Level the bottom
frame and fix it at the bottom. Adjust the distance between
the frame and the sash to ensure that the sides are
parallel. Then make sure that the bottom frame and bottom
sash are also parallel. If uneven rafters cause the frame to
twist, adjust the frame using the variable thickness support
plate supplied. Having adjusted the roof window, fix it as
described in the installation instructions.

RUC UNDERFELT FOIL COLLAR

For the easiest connection to underfelt, use underfelt
collar RUC. The underfelt collar is made of diffusion open
material and can therefore be used for both ventilated and
unventilated roof constructions. The underfelt collar comes
in one piece, cut exactly to fit the window so you don’t need
to cut it. Position the drainage gutter immediately above the
first continuous batten above the roof window so that it can
drain off water from the underfelt above the roof window.

FLASHING INSTALLATION
– RECOMMENDATIONS

FLASHINGS FOR TILES

when installing flashings onto profiled roofing materials it’s
important that both foam gaskets and the flexible part of
the bottom flashing section fit tightly to the roofing material
to avoid drizzle, drifting snow or driving rain entering under
the flashing.

STEP A

For installations using KTF or KUF flashing variants
(depending on the tile height), it is recommended to
chamfer the roofing material below the roof window before
fitting the bottom flashing section.

STEP B

To ensure optimum installation, position the bottom
flashing section temporarily and shape the flexible part to
the profile of the roofing material. Remove the flashing and
then bend the flexible part slightly before re-positioning
and fixing the flashing to the bottom frame of the window.
Bending the flexible part ensures a tight connection to the
roofing material.

STEPS C AND D

Fold in the bottom side of the flashing section at the sides.
In shallow pitched roofs, this is particularly important as
an extra guarantee against water ingress.
The front edge of the flexible part of the bottom flashing
section may be dressed further to fit tightly to the roofing
material.

STEP E

To allow for correct overlap between the roofing material
and the flashing, it may be necessary to remove a nib from
the tile.

STEP F

As screws must not be fitted in the flashing, it may in some
cases be necessary to secure tiles with wire and/or adhere
to the adjoining tile with appropriate sealant if possible.

FLASHINGS FOR SLATES

STEP A

When installing flashings in slated roofs or similar roofing
materials, it is important that the bottom flashing section
overlaps the roofing material with at least the same overlap
as applies to the roofing material in general.

STEP B

To provide the best possible drainage around the roof
window, make sure the distances between the roofing
material and the window comply with the installation
instructions.

When using flashing KSF, the top flashing section must fit
tightly to the window top cover. As the top flashing section
follows the slate course, it willin some cases it will lift too
much. In these situations, the filler piece supplied must be
used to fill the gap.
The same problem might occur when installing in roofs
with roofing felt where numerous layers of felt can lift the
top flashing section. Here too, it is important to use the
filler piece to ensure a tight connection.

HEALTH AND SAFETY

Certificates

Installation instructions showing the the correct method
of installation are supplied with every Dakea product.
Handling of the product – from delivery to finished
installation in the roof – depends on the product type and
size and the installation conditions present. In many cases,
Dakea roof windows may be installed from the inside so
that working on the roof is avoided.
In some cases it is, however, necessary to carry out part
of the installation from the outside, and in these cases
it is important to take all necessary protective measures
against the risk of falling and dropping items, in accordance
with the provisions of the Health and Safety at Work Act.
Safety measures to be taken depend on the conditions
on the building site and are the full responsibility of the
person(s) involved in the work being carried out.
