We need to replace the front entry door on our home and I know next to nothing about doors. I have been reading a little and the only thing I'm certain of at this point is that we want fiberglass. Beyond that I don't know what to look for in door or what brand to go with. I've seen much written online aboput Pella, Anderson, Masonite, Thermatrue etc etc but good and bad for all of these and other brands. Can someone provide some ingiht into these brands and what features I should be looking for? I live in NH so winters here are brutal. Also the door will have the windows on both sides. Thanks.
