We have this nifty “Two over Two” sliding glass door that faces out over the moors behind the Gardens. I am pretty sure that we have the double paned glass door installed on the wrong side (the single pane sliders are on the outside of the double panes). I have searched in vain for an installation guide for this kind of door to no avail.
What this means is that on really chilly days and especially during the awfully cold nights a pattern of sparkly frost develops in the condensation between the doors. It is actually more than a bit pretty.
A sort of sparkly fairyland snow-globey type thing. Pretty much pretty.
