uPVC Sash Window Measuring Guide

To measure for upvc Sash Windows we advise that you measure the brick to brick sizes and deduct 10mm overall if fitting from the outside.

Example – If the brick to brick sizes are – 800mm wide x 1100mm high. You would deduct 10mm from the width and height to make it 790mm wide x 1090mm high.

If installing from the inside you would need to add on for how much of the flat face frame you would like to hide behind the brick/stone work (see image below).

Please make sure that you are happy with the measurements you take as we do not accept responsibility for incorrectly measured windows.
