Installing Glazing Units

Hi all.
I have a timber framed sun lounge, I am now ready to put the double glazed units in.
For security I have been advised to use silicone to fix them in.
Thing is, what happens if you need to take them out for some reason or replace a unit?
Silicone sometimes works so well that it is stronger than the wood and pulls the timber to pieces, also, the pressure needed to push a unit out may be so great that the unit breaks.
Is the advice right or is there an alternative?

Special tools are made to deglaze glass from their openings. The ones I have look like a type of pizza cutter that is at an angle. It will be no problem to deglaze the glass in the future, provided you don't use TOO MUCH silicone, and provided you only use it to seal the exterior of the IGU, not the entire interior perimeter. Remember that silicone is NOT paintable, so if you run a bead of sealant around the window after it is installed, that silicone ought to be tinted the correct exterior color, since it will not be paintable. Clear silicone is usually used in glazing, but often, a final finish bead is applied to the exterior perimeter to enhance the appearance and to ensure a water-proof seal.

IGU's should also be set on rubber setting blocks as padding and to provide a clear air space around the IGU. The rubber setting blocks come in various thicknesses and also act as shims to keep the glass centered in place.

Silicone is the only thing recommended to use in glazing glass.
