I am designing a new residence and it will have two window wells, lean-to style, approx. 11 ft x 4ft in size. I would like the window well covers to be constructed out of aluminum & polycarbonate materials and for the mullion sizes to be 1-3/4" or 2" tube similar to storefronts. I would also like a section of the covers to be operable with assisted gas pistons to allow the young and old to be able to exit in an emergency without the strength of lifting the window cover section. Is there someone out there in the retail market who makes such an animal?
