Penthouses are typically four louvers joined together with a roof, are mounted on a curb, and can be fashioned into custom shapes. Ruskin® assembles penthouses that are ordered up to 60” x 60”. ANY louver model can be made into a penthouse and some models are even approved for hurricane prone regions (carry an NOA). Penthouses that are “oversized” are shipped loose and assembled on the roof of the structure. Click here to view Ruskins' Penthouse products.
