larger windows

A professional from Nantucket Ma says:
Contractor ordered wrong windows and I am remaking larger ones. These are double hung single pane windows. Going from a 20"x 24" tall sash to a 22"x 28" tall sash. I need similar balances and the weather stripping. Can you help me out? Thanks Carter

Hello,

We carry a selection of wool pile weatherstripping, which you're welcome to look through here. Unforutnately, our wool pile replacements use a flat backing for installation. Since yours uses a kerf, our best match would be the 58-053 depending on how the dimensions compare to yours. With that being said, ours uses a bulb to fill the gap rather than pile. Since it is a different type of seal, we can't make any guarantees but review the dimension below and see what you think.

As for the balance, unfortunately, we are not able to determine the correct replacement balances for a custom-made window like you've described. I can tell you that the balances shown in your photos looks like it is for a non-tilt hug window but it looks like it may have missing end fittings, which you would need to determine the series. 

The other possibility is that the balances may be designed to be installed in the header of the window above the sash. If so, unfortunately, that is not something that we'd be able to supply. We'll relate a few videos on this page to help point you in the right direction.
