Knockety’s Fiberglass Craftsman doors utilize “flush glazing” that has no raised molding around the glass panel as shown in the photo at right. This flush-molding appearance is identical on both the front and back sides of the door. These glass panels are replaceable if ever broken. Choose from four different glass texture options to complement your Fiberglass Craftsman door. Glass textures shown are produced using a double insulated glass unit to provide safety, security, and energy efficiency.
