i was talking to someone in the industry and he mentioned how "tilt in slider" experience problems no matter how high quality they are. is this true and what are the reasons ? he said a regular slider is not as efficient as a double hung but if you need a slider so not get a tilt in.. any opinions here?
Yes, I agree. They're problematic from day one. Even when you get the sills perfectly level they don't like to close properly. Also water will weep inside in a downpour. It stays in the tracks but it's a guaranteed phone call. Marvins are the only ones I know of that have no problems.
