The St. Lawrence screen and storm door gets its name from the magnificent St. Lawrence River. The door was designed to have added strength yet allow maximum visibility for soaking in that beautiful view from your front entry. The door comes standard with a removable fiberglass screen insert that can be upgraded to a more durable copper screen if needed. Tempered glass storm inserts are available and easily interchanged for winter months. Two-piece screen and storms are also available, allowing you to have a pet screen in the bottom or leave the glass in the bottom while keeping a screen in the top. Both help to minimize screen damage from pets or children.
