Installation

Windows can be fitted either during the course of
construction or fitted into preformed openings at
a later stage. Building-in factory finished windows
during the course of construction should be avoided if
possible, if however this is not possible, the materials
adjacent to the opening should not be fitted tightly in
order to prevent distortion of the frame. Fully finished
windows should be installed into preformed openings.
Side tolerances between the frame and the structural
opening should not exceed 10mm on each side.
It is recommended that the opening into which the
window is to be installed is 12mm larger (6mm each
side) in both height and width than the overall window
sizes given in the table below:
Module Size
1200 x 1050mm
1200 x 1200mm
1770 x 1350mm
915 x 1050mm
When not building-in, openings can be formed
using either proprietary templates or site constructed
templates, these templates should produce openings
that are between 10mm to 20mm larger than the overall
actual window size depending on the the installation
method.
Lintels should be positioned clear of the window head as
windows must not be used for load bearing. Pre-formed
openings should be larger than the frame that will be
fitted into them. A tight fit could cause distortion of the
frame. A clearance of at least 5mm should be provided
all around the frame, however, clearances more than
15mm will be difficult to seal after the frame is installed.
Building regulations require the installation to achieve a
level of airtightness

FITTING & FIXING GUIDELINES
We recommend the Illbruck i3: system for high levels
of air tightness. There should be a correctly installed
damp proof course around all the openings to prevent
moisture moving from the outer construction to the
inner construction.
There should be adequate insulation fitted between the
inner and outer construction to reduce heat loss at the
window openings. The window should be positioned
in the opening such that it covers at least 30mm of the
insulation.
Note:
• Proprietary insulating products may have particular
requirements for installation. In these cases follow the
manufacturer's recommendations.
• When installing windows into timber frame
constructions, care must be taken to allow for
differential movement between the external
construction and the timber frame and for fire
stopping at the window opening.
Windows should be fitted without distortion. They
should be levelled and upright and the position
checked with a spirit level.
Windows should be secured in the openings by fixings
at each side positioned approximately 150mm from
the top and bottom of the window and then at no
more than 450mm centres in between. Fixings are not
required at the top and bottom for frame widths up to
1800mm, for wider frames up to 3600mm, a central
fixing will be required. When securing the frame care
must be taken not to distort the components as this
could impair the operation of the window.
