Help! Looking into French door entry, fiberglass with 1/2 to 3/4 glass. I was considering Therma Tru but heard they don't stand by their warranty & had issues. How is Masonite? feather RiverOr other manufacturer? Thinking of buying at Home Depot. A "lumbar" place told me Home Depo sells cheaper version of TT. My old doors leaked but that was way installed, but glue was coming out and glass frame was breaking. I get Southern exposure so gets heat. Thanks for any advice. Plan on selling in 2-3 years. J
