If you are asking about wood trim, then what you see is a reuse of what was once a snow fence. The grayish color you see is simply the result of years of exposure to the elements. Nothing was added to the wood to achieve the color you see. Hope this helps!

Would having wood like this last after years of exposure? Has it been treated?

The wood has not been treated in any way and is expected to last for many, many years just like an old barn that's been standing for more than a century with little maintenance. One of the things that folks love about copper roofing is the beautiful greenish patina that develops naturally over a period of many years and what you see on the wood is its natural patina that will continue to evolve as the years go by.

Beautiful Combination! What color are the windows?

Thank you! The windows are made by Kolbe and the color is their standard bronze as I recall.

Are the windows vinyl or wood?

The windows are wood with metal clad on the exterior.
