Recently someone posted about a product featured on This Old House that will
insulate the sash pocket of an old window without getting in the way of its
opening & closing. I searched TOH site but can't find it.
Can someone provide an URL?
Yeah, there was a post a few days ago about someone using PVC pipe for the
weights. I think that's a waste of time and energy. How are you going to
get the pipe in there, tie the knot on the weight and install the
insulation? What kind of insulation? Will you be able to get the the pipe
out if you use foam? What a mess if it is fiberglass.
You're looking for a "pulley cover". Andersen makes one of vinyl that
just lets the cord out the bottom; there seem to be cheaper self-stick
models available too (maybe they're just weatherstripping for the
existing flat cover). They're hard to find online, though.
