Q's: Precautions for fiberglass entry door vs the sun

We live in NY, and replacing a west-facing old steel entry door that gets afternoon sun. Shopping for a fiberglass door. Aware of concerns regarding fiberglass doors that get sun exposure, therefore will buy a good quality door (Therma-Tru or similar) and will be painted white or light gray. Will go with no storm door initially to avoid trapping heat and the problems pushing the door closed against air trapped between. No storm door will also provide easier access/egress.

If we eventually get a storm door, it will be a roll-up screen model and kept vented except in winter. Will also get low-E glass, or apply reflective film.

The sales guy at the big box store strongly insisted no fiberglass door for any sun exposure, due to heat/warping. Explained the above precautions planned, but he remained adamant that we should not get fiberglass.

So now ask DIY experts -am I correct to think this sales guy is way to extreme in his thinking, and that the planned precautions will protect our new fiberglass door from warping?

Thanks for your time

I've installed hundreds and the only problems anyone has ever reported have been with west facing doors that were later covered by full view unvented storm doors. They were stained medium oak, so they got quite hot.

Also have had problems with the plastic around the glass getting warped, but that's probably more the fault of the crappy plastic they got from china.

Your response appears to confirm that a good quality, vented fiberglass door painted white or another light color should be OK with some late day sun exposure in NY.

A stained medium or dark fiberglass door behind a full glass unvented storm door and exposed to the sun is asking for trouble. Unless anyone argues otherwise, consider the plan for our fiberglass door to have low risk of resulting in sun damage.

Make sure you order it "storm door ready" so that the stiles/mullions, if sidelights are built up to allow for the installation of a storm door. Having lived in both Upstate New York and Southeast Virginia. Upstate never approaches the heat extremes that we face down in Virginia. Keep the color scheme light, ThermaTru is an excellent door. I have never had problems down here with that brand.
