STEP 7 - Refit the refurbished sealed unit in
the window frame....
As with the removal of the sealed unit, the
particular procedure for its re-fitting to the frame will
depend on your frame type - I can't offer much help here I'm
On my window the unit is fitted from the
outside - with care taken to make sure it went back in the
same way it came out - ie with the leaded bars properly
lined up with the neighbouring panes.
Failing sealed double glazing unit - moisture
induced misting developing between the panes...
After the repair - misting gone and as clean
as you make them....... glass, spacer bars and corner keys all
It's only been six months since I refurbished
the first of my misting sealed double glazing units, so I'm
not yet able to judge the longer term durability of the
repair yet - however they are all looking good with no signs
of problems so far. The life of the repair will depend on
how well the silicone sealing holds out and how well the
generic silica gel desiccant performs.
April 2012 update for improvements to the process by
reconditioning the glazing desiccant.)
The cost of the repair was minimal compared
to cost of new double glazing for the house - the major part
is my time to do the work. Material bought was the silicone sealant, the silica gel, Stanley knife blades, window
cleaning spray etc
Given the very low cost I think it has been a
worthwhile exercise and should put off a good few years the
evil day when we have to give up on our old timber farmed
windows and fork out for a new set of windows for the house.
