Is it easy
to install a roof window? A: Installing a roof window is quick and easy. The window comes with an easy to follow installation instruction. For a step-by-step guide, see the photoguide on www.fenstra.net. You can also download video footage there if you have a suitable Internet connection.
The
distance between the rafters is too small for the window. What should
I do?
A: You can solve this problem by trimming the rafters in order to create
the correct space. Note that rafters should have a distance of max. 30
mm on either side of window.
The
distance between the rafters is too wide for the window. What should I
do?
A: In this case, you should frame out around the window by packing out
the rafters. If the distance to the frame is still too wide (more than
max. 30 mm on either side of the window, horizontal beams should be placed
between the rafters - and a vertical rafter should be inserted between
the beams.
What
type of under-roofing should I use?
A: Any type may be used but take care that it is not perforated during
the course of the installation to ensure a watertight installation.
How
deep should I install the window into the roof?
A: The black line on the side frame should be on the same level as the
top of the horizontal battens on the roof. The angle brackets included
in the window box (positioned on the top corners of the window when opening
the box) should be fitted accordingly.
How
should I shape the interior finishing around the window?
A: Over the window, the interior lining should be horizontal (parallel
with the floor) whereas it should be vertical below the window (perpendicular
to the floor surface). These precautions should be taken to ensure optimum
flow of air and maximum light. Be careful that a windowsill placed directly
underneath the window does not obstruct the flow of air by leaving an
air gap between the sill and the wall.
Is it
necessary to have a heating element near the window?
A: We recommend that a heating element be placed underneath the window
in order to minimise condensation on the pane.
