Water is more likely to freeze on modern double glazed units than on old fashioned single glazing.
Providing the temperature is cold enough of course.
On single glazing the warmth from inside the building is easily transmitted through the glass, on double glazing obviously the insulating effect works both ways, therefore the heat from the building doesn't get through to the outer layer of glass, ergo, if cold enough, water will then freeze.
But even when it does happen, it is most usually very early in the morning, and boy, does it have to be cold for that to happen!
Water freezing on the pavement is easily dealt with.
When the temp gets down that low, I carry a container of road salt in the back of the van.
You don't need shovelfulls of the stuff, you throw it out very thinly.
And its best to do it before you start spraying the water about too!
Squeaks reckons pedestrians will slip on the gravel in it, but I'd love to see him prove that.
It gives you more grip, not less.
