How to swap out glazing from aluminium windows

Take out the rubber gaskets from the inside that will allow the outside bead to be removed fit new glass re fit beads then re fit inside rubber gaskets

Hi nick all the old ali windows were externally glazed and normally have gasket on the inside that needs to be removed first before bead removal outside

If the beading on an aluminium frame is external then it will definitely have a wedge gasket internally which insures the beads can't be removed from external without first removing the internal wedge gasket first, thus making your home secure. So to remove external beads first remove internal wedge gasket with a paint scraper nothing to sharp however are the gasket may get damaged, push the corner of scraper gently into corner of gasket inbetween the frame and the side of gasket that is up against the frame and and try and drag the gasket out by moving it out over towards the centre of the glass if you can imagine having a wedge of wood stuck under a door this is exactly what the gasket is like apart from there's a slight groove in the gasket that keeps it held in position removed and keep safe all gaskets to replace after unit is exchanged feel free to call me if you have any problems Kr John Northfix Ltd
