No one will know this isn’t real stained glass! Stained glass films are durable, high-quality 12 mil thick films that emulate the look and feel of stained glass. When applied to existing windows, the sun filters in the deep, rich colors in the pattern and drenches the room in colorful light. The resulting glow adds beauty and sophistication to the environment. Application is surprisingly easy and it is a popular choice for homeowners. All of this comes at a fraction of the cost of real stained glass.
