My 1987 built house still has the original windows. They are aluminum-clad double-paned glass (both windows and sliding glass doors). I have replaced a few over the past couple years because the inner seal goes bad and condensation fogs up the glass. By replace I mean I take them to the glass shop and they put new glass in with a fresh seal.
I can always feel significant coldness from them in the winter when I approach them. There aren't any leaks around the edges, it is just cold air 'radiating' off them and the aluminum frame. It feels like this cold air then drops down to the floor and generates a cold air movement almost like a leak. I feel this cold air movement but don't find any leaks feeding it, so I assume it is cold air dropping and creating the current.
I know new windows are much more efficient, but do folks with new windows still feel coldness as they approach the glass or sliding door? Or are they so efficient you don't even feel this? My heating cost in Virginia (via heatpump) is probably ~ $850 (and that might even be a high estimate) so it would take a long time to recover the expense of window replacement. I'm assuming decent windows installed would be over $3000 with a 7 year or longer payback.
Anybody have new windows lately and have any thoughts to help guide me? I probably need a new heatpump anyway before investing in new windows (original heatpump too!)
