If the window is Andersen, then I think our 20-015 would be a good place to start. You may also want to use a silicone spray on the window tracks to help in the raising and lowering of the sashes.

I'm sorry! I think Paul was implying that the lubrication would make the windows easier to open without changing anything around.
To be honest, it's difficult to say anything for sure without actually seeing the sash you're going to install these pulls on. If you want, you can take a few photos of the window and a close up of where you will be installing these pulls and we can see if there would be any complications. Also, can you confirm that these windows are Andersen brand? Are the sashes made of wood or vinyl? Also, on the "hard to open" issue, how old are your windows? I'm thinking maybe the balances or springs inside the tracks could be wearing out, as well. I hope not, since it may make things a little more complicated. As for the lubricant, I have heard a few ideas on what to use. The silicone spray could yellow the vinyl, but it is often the preferred lubrication since it does not gather debris or dust. WD-40 could dissolve some vinyls, as well. Teflon spray might be a good alternative, but I myself have used Silicone spray with great success in the past. It depends on the vinyl compounds used in the window, which is difficult to figure out, as you can imagine. |
