Hi, we fitted 2 new double glazed, top opener windows to our bedroom saturday, fitted no prob - looking great. Went to bed sunday night to be woken by a scratching sort of sound coming from window, when i checked to see what was happening 2 cracks had appeared both starting from the same point at the bottom of the window travelling across / up in a "V" shape with small splinters of glass inside unit, the crack is on the inside and a ridge is evident when touched. Does anyone have any idea why this could have happened when it was fine for over a day after fitting and cleaning?? The glass is pilkington K.
Thanks
