I would like to install a UPVC window upside-down. It is this style of wind ow: http://wickes.scene7.com/is/image/travisperkins/E1173_113061_00 ?$normal$
I want to install it so that the opening section is at the bottom. I'm gues sing that I simply need to unscrew the hinges, and then screw them back on in a new position. The mushroom keeps would also need screwing onto the opp osite side of the opening, so that they will be at the bottom when the wind ow is installed. (It has this type of shootbolt espag mechanism):
Am I missing anything? Any tips on repositioning the hinges, etc?
