How
to measure a double glazed door and window
These guidelines are to help you
measure for a new double glazed door and/or window and make an
accurate measurement.
Measure the opening outside on both
the height and
width. Always measure the exact brickwork opening and not the
old frame or door.
Measure brick to brick in at least three
different places and deduct 10mm from both the final height and
width measurements to allow for 5mm fitting allowance around the
new frame. This will enable you to ensure the new frame sits plumb and
square once in the aperture. Spacers and filler will then be required to
secure the frame into place and fill any gaps.
-
Do not measure your existing door or frame but measure the
brick opening.
-
Measure in at least three
different places and deduct 10mm from both the final height and
width measurements - we do not make any fitting allowances on
the sizes you provide.
-
Measurements will need to include
the frame, cill and any frame extenders/add on’s required.
-
All dimensions to be
supplied in Metric and all designs viewed externally.

The width should be measured
brick to brick at three points
- top, middle and bottom of the opening. The smallest of these
measurements is taken as the width. Always deduct 10mm from the final
width.

The height should be measured
brick to brick at three points
- left, middle and right of the opening. The smallest of these
measurements is taken as the height. Always deduct 10mm from the final
height.

Please measure as above but
also...
the side panel width should be
measured from the centre point of the frame between the door and the side
panel to the outer edge of the side panel frame.

Please measure as above but
also...
the top light depth should be
measured from the centre point of the frame between the door and the top light
to the top of the door frame. This will give you the transom drop for the top
light.

Square Bay windows consist of three sides and two 90 degree corner
posts. The width (back span) will need to be measured internally from the existing frame edge to
edge. Measure each side window internally
and ensure they are the same from one edge of the frame to the other.
The height will need to be measured externally brick to brick including any
existing cill.
We
will add 140mm to the external size for the two 90 degree corner posts which
are 70mm square.
For
example, if the internal width is 1800mm the external width including two 70mm
corner posts will be 1940mm, see image below.
Bow windows are slightly more
complicated than bays, consisting of two or more sides and shallower angles. The width (back span) will need to be measured internally from the existing frame edge to
edge. Measure each individual window
facet internally from one edge of the frame to the other. The projection
of the bow will need to be measured internally from the inside back span of
the window to the inside point of the window frame as below. The height will need to be measured externally brick to brick including any
existing cill.
