IMO black windows are best when they are metal and factory finished to with stand the sun without fading. I am sure there are fiberglass ones I would just prefer metal . As for the choice of black outside and white inside most makers offee that . As for the hardware on the black windows I think black on them is better but it depends on the style of window too.

Depending on your location we could help. Solid core composite windows are light years ahead of any vinyl window out there. The problem with fiberglass is it’s super expensive and the etching primer has to be perfect in order for paint to last on it. Composite windows are durable in strength and perform as equal or better to a fiberglass product without the hefty price tag. The real advantage in your situation is the super cap exterior acrylic finish on the exterior of our composite windows. This paint gets baked on and then another layer of clear coat on top of that.

Marvin, Milgard, and Kolbe all offer fiberglass windows with black exterior and white interior.

"Marvin, Milgard, and Kolbe all offer fiberglass windows with black exterior and white interior."

Marvin Essential & Kolbe Forgent are only available with Black on both interior and exterior. Black is not available as a split finish from either manufacturer. Not certain on Milgard.

Interesting. The Marvin and Kolbe websites only state that black interior is restricted to windows with a black exterior. No corresponding language on exterior colors. Milgard does explicitly state that any exterior color is available with a white interior.

Kolbe Forgent black exterior windows have several white interior options: 1) white Glastra, 2) white factory painted wood, and 3) primed wood. They are also available in several wood species in case you want to stain them.

Their wood interiors are an over-layment that attaches to the fiberglass interior, so the wood is not exposed to the elements outside. I just installed black exterior/white wood interior windows 6 months ago and LOVE, LOVE, LOVE them and would make the same purchase again.

The Glastra window frames themselves only come in two colors: white and tan (Sahara). Then, if you want black or bronze, they paint a very nice and durable coating over the white or tan Glastra/fiberglass window frames. On the outside, the entire frame is coated. On the inside, there is a portion of the frame that is uncoated, so you will see a difference between the bronze/black and the white or tan frame. (I am speaking only about casement windows and can't speak to what they do on other window types.)

See photos below.

#1: black exterior, #2: white wood interior, #3 white Glastra interior, #4 showroom model showing tan/Sahara color Glastra base with black interior coating. When the window is closed, you cannot see the Sahara color Glastra. When open, you can see it well. Not sure why, but they do not offer black or bronze Glastra base; just white or tan and then coated, which gives mismatched color interior when windows are open.

More photos.

Those are significantly better looking than the Marvin Essential window I just ordered. I will definitely give Kolbe a close look when it's time to replace windows in the rest of the house.

is it more expensive to go with balck exterior windows with the interior white?

Yes it is. But each company charges differently and offers different types of product.

I ordered Kolbe Forgent black exterior/white interior with Glastra (proprietary fiberglass) both inside and outside for our garage for weather, dust/dirt, and cleaning reasons. I ordered Kolbe Forgent black exterior, wood interiors that we had painted on the interior house.

For hurricane impact, laminated, insulated, low-e windows, the cost difference was $110 per 36x72 window. The wood interiors and the different screen that comes with them are prettier than the Glastra white interiors, hands down, but I wanted easy maintenance for our garage, which is open to my husband’s woodworking shop.

These are Aug 2021 prices for same size windows. You can see the individual price add ins for exterior (black), and interior wood.
