crazySN thanks for asking this...I've been trying to find a good fiberglass 8'0" door that is 42" wide, and I can't find one in the style I am looking for. Actually, the designer had drawn in a 48" door, but I can't find anything that wide. I was starting to look at custom wood doors, but had the same concerns about energy efficiency and maintenance. I was looking online and came across Borano...their quote wasn't as high as I was expecting for a solid mahogany door and they had a style I liked, but it's still wood. I'd be interested to hear from folks with wood doors, or if anyone knows of a manufacturer that will make a custom fiberglass door.

I want to get a new front door, half-window and made of fiberglass with fake grain. I would like to try a darkish green or blue paint on the exterior and brownish gel stain on the interior (to match the woodwork). Door faces east-southeast. Current door is steel painted dark brown (BM paint); it shows some fading after 10 years (probably faded earlier, but I just now questioned the color). Would the paint color fade? Would fading green be less objectionable than fading blue? If I don't like the paint can I apply stain over it? Which lasts longer: stain or paint? What do you do with the edges (top, bottom, and sides) of the door? Match the inside color or the outside? The trims on both the inside and outside are some sort of brown (stain and paint). Thanks for any help.

I've also thought of building a little awning or cover for the door to provide some protection from the sun... You'd have to make an awning that is 10' deep to be any use with a west exposure. The reason is the sun does its damage late in the day when it's lower.

I think this is a question for the manufacturer. They probably have some kind of research on their white doors yellowing. Perhaps rethink the white door if there is a chance of major yellowing in 10 years. Or sooner. Seems weird to me to spend the extra dollars for a fiberglass door and then paint it because it yellows. Choose another colour and go with maintenance free (maintenance free is the biggest selling point for a fiberglass door).
