double glazing

how do i get the external glazing beads the rectangular ones out of a double glazed frame to replace the unit

The removable glazing beads should be on the inside only - otherwise any old robber could prise out the beads from outside and get into the house just by removing a pane of glass..

remove the gaskets from the inside first, this should free the glass sufficiently to remove the beads.

Depends on the design of the frame . . . . .

Had some in the last house where you remove the rubber strip around the inside between the glass and the frame, go outside and push the glass inwards (about 3-4mm), prise out the beads, remove the glass. Fitting is the reverse.

The ones we have now are different. Prise out beadings with broad bladed paint scraper or similar - start with the one that sits ovet the top of the others at the corner - probably a long one. Cut the self adhesive strip on the inside of the glass and remove pane. Clean off remnants of self adhesive strip. Go buy some more self adhesive strip and refint etc.

If you can see the self adhesive strip (looks like 3mm thick sponge) you have the second type. It is this self adhesive sponge that stops the late night visitors taking the glass out without waking you.

Sometimes the beads are just difficult to get out.
