Grandma's house had 'em. Ours is a new house (7 years old) with builder
basic vinyl windows. There's one huge (6050) picture window on the north
side that just sheds in soooo much cold air - it's unbelievable!!! In
winter, the cold air just cascades down the thing!

Budget's very tight - and I'm rather look for some inexpensive ways to
address the draftiness without looking at a replacement yet.

Put up some of that clear plastic sheeting - and it helped. But am now
looking for something that might last 3 or so years.

Watched an episode of This Old House where they had new windows going in a
historic house - and they had "energy panels" - essentially Storm Windows on
the inside.

That got me thinking - does anyone think a storm window might be a
reasonable approach on this picture window?
