The 4500 Series Sliding Glass Door from Monumental Windows and Doors is designed with European style and manufactured with California craftsmanship. These luxury sliding glass door systems are far superior to standard commercial gliding doors. Monumental sliding doors are made with durable, environmentally friendly aluminum, thermally broken frames, and are designed to accommodate huge custom glass panels—up to 8 feet wide and 12 feet tall!

Our newly designed flush pulls and latch assembly are made of aircraft quality precision-milled stainless steel, with a large actuator for finger-touch operation. The maximum security laminated hook-lock is an industry standard and has been used for years by commercial door manufacturers to meet strict forced-entry requirements. Numerous configurations are available, along with custom sizing for special projects.

Luxury Glass Sliding Doors from Monumental 

Sliding glass doors have several advantages over traditional doors. Firstly, they provide a better view and allow more natural light into a room, making it brighter and more inviting. Secondly, they are more space-efficient, as they slide open and do not require any additional clearance for swinging open. Thirdly, they are easier to operate and maintain compared to traditional doors with hinges and handles. Lastly, sliding glass doors can improve a home's energy efficiency by providing better insulation and sealing.

Eco-Friendly, Green Building Options

There are also the clear advantages of our thermally broken aluminum framing. Doors framed with thermally broken aluminum offer several advantages over traditional doors. They provide superior insulation and reduce heat transfer, improving energy efficiency and comfort in a building. They are also more durable and resistant to weathering and corrosion, making them ideal for use in harsh climates. 

Thermally broken aluminum doors are also lightweight and have a sleek and modern appearance, adding aesthetic appeal to a building's design. And finally, they are low-maintenance and require less upkeep compared to traditional doors, making them a cost-effective option in the long-term. Thermally broken aluminum frames are even recyclable, making them the most environmentally friendly choice.
