well its much more comfortable to have it fitted when the weather is nice.....but having said that, round me last summer was on continuous storm pretty much..
I was thinking more about the sealant not drying properly or water being in the recesses when the units are put in , affecting the units in the future .
Sorry Bazile I had visions of you sat in front of the telly in your coat when your windows are removed .. when you fit units you dont use sealant at they are sealed up against the outer rubber seal when the inner beads are pressed in place. Anyhow the fitters will be sat in their van if it rains.
These days there are plenty of adhedives that work well even under water so dont worry.
My plan was to tell her indoors, that it's not reccomended to fit them in winter ; thus given me the chance to put this on the back burner until next year and deal with other pressing matters .
Still it's good to be educated on things like this .
