Spcifically duuble-hung, sliding ones. What people call "old fashioned sash windows".
I've been looking on Mighton's site. I quite like the look of the plastic parting bead, and the standard weatherstripping, to be installed in 2mm grooves in the staff bead, the stiles of the sashes, or the front facing of the boxes themselves. Not at all sure about brush seals various, I think they will attract dirt and become unsightly very fast.
Any relevant experience?
Disappointed with brush pile, though that may in part be due to the inept design of the windows. Not very effective draft proofing.
I have double and single sash windows in the upstairs front room. Rebuilt the double one using new beads with that slide in brush stuff. And added it to a sash where the two meet. So have a pretty direct comparison of with and without. If the windows are in good repair and you take care fitting the new beads I'd say the results well worth it. I'll do the single one when we finally get spring. ;-)
