Did you know Lang offers V-Groove decorative etched window glass?

V-Groove glass is a decorative V-shape carved into the glass of your windows in a pattern of your choosing. Many patterns are available, including curved shapes. V-Groove window glass also creates a beautiful prism effect in sunlight. Lang Exterior V-Groove window glass is beautiful and maintenance free, just like our between-the-glass regular grids.
