Technical Resources

Cross Section Drawings

Cross section drawings are detailed diagrams that allow the viewer to see the structure of our doors and windows as if looking at a piece of the product cut to expose the inner workings of all the parts. These drawings are created and provided by our engineering department and are color-coded and clearly labeled with a layperson’s terms and identification number.
