I’m going to be doing a pretty extensive remodel on Cape Cod and would like to spec. aluminum clad windows, Marvin or Kolbe, and would be interested in any input about using clad windows in a seaside environment. I want the windows to be maintenance free but still have the detail of a SDL window.

Most of 'm have got the coatings right by now. just do the purchase order/quote request so the company knows it is sending them to water and then it's their cost if they need replacement. Both Anderson and Marvin took some hits about ten years ago on this but they did the right thing.
one thing to check is if the cladding is extruded or formed on a brake.. the extruded ones weather better.. the braking stresses the aluminum and they corrode at the the bend points......
not much of a problem until you get into a coastal enviornment...

I didn't know anyone was still buiilding windows without extruded. Must be that's all they sell here, knowing the market.Excellence is its own reward!
The aluminum extrusions are much thicker than roll formed and more resistant to impact damage as well. It takes a pretty hard hit to ding up extruded aluminum.

Kolbe still uses roll form on their windows. If you are looking for window that is a better price than Marvin try Norco. All extruded, a very good value.
I've used Norco's on three or four jobs now and really like them. They've got pretty good prices on custom layouts too.
One of their intresting items is a casement window with applied muntins to look like a double hung. You get the DH look and the casement efficiency.Excellence is its own reward!
A couple of thoughts for you to consider. Extra paint, touch up occasionaly to keep the salt out. Keep the weep holes at the bottom clean so the salt does not build up. Rinse occasionally, for the same reasons as above. As you can tell, I am the one guy left that likes vinyl, if done well. Here in Hawaii, the salt eats aluminum, which helps keep me busy so thats ok. I suspect that the new stuff is better, but I need time to be convinced. Just opinions.

Just a couple days ago I spoke with Marvin's Architectural Hotline about this (but for the Gulf Coast) and they said they offer a good warranty and stand by it in those climates, so they aren't expecting to have problems.
