How to measure
These guidelines are to help you measure for a new composite door and frame, if you are unsure we recommend contacting a local door installer to carry out a site survey.
Measure the both the height and width from the OUTSIDE. Always measure the exact brickwork opening and not the old frame or door currently in place.
Measure brick to brick in at least three different places and deduct 10mm from both the final height and width measurements to allow for a 5mm fitting allowance around the new frame. This will enable the new frame to sit plumb and square once in the aperture. Packers and silicone will then be required to secure the frame into place and fill any gaps.
- 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 provided.
- Measurements will need to include the frame, cill and any frame extensions required.
- All dimensions to be supplied in Metric (mm) and all designs are to be viewed from the outside.
- Always check your measurements at least twice to ensure you have the correct size.
- Ensure the frame size is smaller than the brickwork opening.
- Do not measure your existing door or frame but measure the brick opening.
Single Door & Frame
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.
We are unable to accept responsibility for incorrect measurements. If you are unsure we recommend that you contact a professional door fitter, joiner or builder to carry out a site survey.
