Ext door steel or fiberglass or?
The exterior door leading to the deck on the back of our home is going to need replaced. It gets full sun in the summer (nwTN) that causes a lot of contraction-expansion and constant upkeep with caulking. Currently it is a steel door, double glass with 15-lite design (not 15individual panes). Recently replacing the door sweep on the bottom of the door noticed that a portion of the door had rusted out and foam insulation deteriorated. A temporary fix of neutralizing the rust and filling with spray foam and recaulking has done the job of blocking air and condensation. This door is original to the house, 18 yrs old.
Sorry for the lengthy explanation, but I need advice on what kind of replacement door to get. And must I get the surrounding framework.
Thanks for your help.
