As standard all of our casement windows are supplied with double-glazed argon filled units, and you have the option to upgrade these to triple glazed argon filled units, for even greater thermal performance.
How to Measure
Measure the opening outside on both the height and width. Always measure the exact brickwork opening and not the old window frame.
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 window 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.
Please remember:
Do not measure your existing window 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 styles viewed externally.
Transom Drop
The transom drop is measured from the top of the outer frame and down to the centre of the horizontal bar.
Mullion Width
The mullion is measured from the outer edge of the frame to the centre of the vertical bar
