Measuring Tips

Every unit is made to order so it is critical that you give us the correct dimensions. The secondary glazing unit ideally is face fixed within your window recess so the dimensions required are the measurements to the outside of the recess. We strongly recommend deducting 10mm per dimension at least to give some tolerance for fitting.
