I live in a region with extreme weather — freezing winters and scorching summers — so my previous door didn’t hold up at all. It warped after a few months, and the insulation seemed useless, making my heating bills skyrocket. I realized I needed a door that could survive temperature swings without losing its shape or efficiency. I’ve been researching fiberglass, steel, and solid wood options, but each has pros and cons, and it’s hard to decide what works best for my home.
