Just purchased a Premdoor 10 light apertured door. PVCu cassette supplied seperately.I am fitting the decorative glass myself. It appears that the maximum depth of glass is 4 - 6mm but the aperture depth is 8mm. How is the best way to fit the glass. Would it be easiest to rebate the door down to 4-6mm as required or has anyone any other bright ideas.
