Counter height window owners--Help!
I've loved the examples of counter height windows I've seen on GW and have asked that our over the sink window (38" wide 34.5" high) be enlarged to a height of 46", which would be the height of the counter. I'd planned that the new window would be a casement window, wooden with aluminum cladding (eg. Jeldwen). The exterior of the house is limestone so some stones will have to be removed and the sill reset. I met today with the GC who expressed a number of problems with doing a wooden casement window at counter height, including the narrow space between the undermounted sink and the window, the difficulty in sealing the granite counter seam with the wooden window frame, the handles for the windows interfering with the use of the faucet, the risk of water damage from splashing to the window frame, that the faucet will be in front of the window and the fact that the frame of the window really wouldn't be at the counter level since the window frame would have multi-levels (ie. the window frame isn't flat so it would be stepped back from the counter level). I think those were all of his reservations. If I insist upon the counter height window, he suggests using a metal window frame or a vinyl window (neither of which I've investigated). The other replacement windows, in the adjacent breakfast room and family room, will be wooden with aluminum clad double hung. The design is very traditional so I'd like to have wooden clad windows, not metal or vinyl. Although DH doesn't *get* the beauty of counter height windows (& wonders whether I will really like it), he's willing to support my vision. I realize that some of the problems could be solved by creating a bump-out on the exterior wall so that there would be greater depth between the sink and the window, however, the bump-out wouldn't blend with adjacent windows that would not be bumped out.
So, GW folks, help me out! What type of windows have you used? Should it be a casement or a double hung or a slider design? How do you seal the granite to the frame of the window? Do you have issues with water splashing on the seam or on the window? What window manufacturer have you used with success? Is the space between an undermount sink & the wall (looks like it will only be about 3.5" from the faucet to the wall) too narrow? The faucet is a Blanco Harvest (single faucet, no sprayer or soap dispenser) and the sink will be a Silgranit or Ticor 1 3/4 design, so the faucet will sit to one side of the sink. Have you had any issues with breaking the window, hitting it while doing dishes, a worry that DH expressed? Have any of your GCs thought your window height window was a nutso idea? I'm relying on you to help me select the right window and coach my GC through this installation! Thanks!
