TThese guides are designed to help you measure your existing aperture. If you’re unsure we recommend you hire a professional to carry out the survey. We can also put you in touch with one of our trusted recommended installers if you don’t have a local builder.

Simply select a product to get started and if you have any questions contact us and we'll be happy to help.

IMPORTANT: With supply only orders we will manufacture to the sizes you enter, so you must make any deductions yourself.

TOP TIP! Measure to the underside of the existing sill unless it is NOT going to be replaced. IE a concrete sill is present. If you do need a sill then enter the overall height measurement including the sill.

Frame Designs

Please note that french doors, patio doors, bi-fold doors and windows are simply treated as single frames. More extensive guides are available when customising a product. When you reach the stage where you enter sizes, you'll see a blue "i" which will provide more details.
