Should I bond my glazing units?

[jayc89]

New windows arrive today, woohoo. I'll be fitting them over the course of the next couple of weeks. The majority are relatively standard uPVC units. When fitting the glazing units should I just use the supplied packers and trim, or would it hurt to seal the units into the frame using a silicone adhesive too? I noticed that's what Rationel do to their fixed units. Am I overthinking things?

I would follow the instructions to preserve any warranty.

 

I've read that packers should really be flat so they support both sheets of glass. Otherwise the weight of one sheet is supported by the seal.

 

Any drainage holes and channels should be kept open to stop water collecting innthem and freezing in winter damaging seals.

Use the Supplied packers Make sure you toe and heel the side hinged windows You may need to get the units out at some stage So don’t bond them in
