Fixed Frame Windows
A fixed frame hardwood window, known commonly as a picture window, is a non-operable window that creates the appearance of a picture frame on the wall.
They are commonly installed as a single window or used in combinations with more functional window types creating a spectacular window wall. These hardwood windows are always custom built to your precise specifications to help bring your vision to life. Create a unique appearance from the interior and exterior with large and flat glass surfaces.
