How to measure for your casement window or door / patio / bifold

Step 1

Height and width

Measure the height and width of the outside of the opening. Remember to measure the brick to brick size and not the sizes of the old frame / door.

Step 2

Aperture

Measure the width and height in at least 3 places on the aperture, and you will need to deduct 5mm from around the frame (10mm from width and height) to find the fabrication size needed for your frame to fit perfectly within the opening. Packers and filler will be required to ensure the frame is secure.

Step 3

Cills

The measurements you supply for the frame / door will need include any cills or build up that is required.

How to measure for your bay window

Step 1

Measure Aperture

Measure your height externally brick to brick, and remember to include any cill you require in this measurement.

Step 2

Size of Sections

Internally measure the width each section of the bay edge to edge.

Step 3

Measure the Angles

Provide us with the internal angles so we can supply the appropriate bay poles and do any necessary deductions.

How to measure for your windows

 

How to measure for your bay window.

Measure your height externally brick to brick, and remember to include any cill you require in this measurement.

Internally measure the width each section of the bay edge to edge. For a 3 segment square bay, a 90 degree corner post will be supplied and we will not need to know the angles (and no deductions will need to be made). But for a multi-segment bay (ie 4+ segments) you will need to provide us with the internal angles so we can supply the appropriate bay poles and do any necessary deductions.

 

How to measure for your bow window.

To measure for your bow window, you will need to measure the external brick to brick height and width of the opening (deduct 10mm from your height and width to find your fabrication size). If a canopy is required, we will work out what projection is needed on your bow window, but should you not require a canopy on your project, you will need to provide us with the projection needed.

 

Measuring for a porch.

Similar to a bay, the internal widths of the window frames/brickwork are required. By providing us with the internal sizes, we will provide cornerpost(s) and will not need to make any deductions.

To measure the height, measure the brick to brick size of the external aperture and deduct 10mm from width and height.
