4510 Folding Door


Our 4510 series is a revolutionary folding door system that is bottom-weighted, eliminating any structural requirements or additional engineering that more traditional folding systems require. The system is designed to support oversized panels and minimum profiles, with excellent thermal values.

With built-in thermal intelligence, this folding door system caters to the latest technology to achieve high performance. It includes a polyamide thermal break, in favor of traditional resin thermal breaks.

Monumental door systems, all framed in thermally broken aluminum, offer several advantages over traditional door systems. 

  • One: they offer improved energy efficiency. The thermal break in the aluminum frame helps to reduce heat transfer and improve insulation, reducing heating and cooling costs. 
  • Two: they offer increased durability. Aluminum is a strong and durable material that is resistant to corrosion, warping, and cracking, ensuring that the door system will last for many years with minimal maintenance. 
  • Three: they offer a sleek and modern appearance, with a variety of finish options available to match the aesthetic of any building. 
  • Four: they are low-maintenance. Aluminum is easy to clean and does not require regular painting or staining to keep it looking new. 
  • Five: thermally broken aluminum door systems are environmentally friendly. Aluminum is a recyclable material and the thermal break reduces the carbon footprint of any building. 

Overall, door systems framed in thermally broken aluminum offer a combination of energy efficiency, durability, style, and sustainability, making them an excellent choice for any building. 

The 4510 folding door system from Monumental Windows and Doors offers an aesthetically pleasing system, an integral concealed locking solution, beautiful finishes and expertly designed hardware.

Folding Door Systems From Monumental

Folding door systems, also known as concertina doors or accordion doors, offer several advantages over traditional doors. They are space-saving — they do not require any swing space, making them ideal for small or cramped spaces. They offer easy and quick access, as they can be opened and closed quickly and smoothly without the need for clearance. 

Thirdly, they are cost-effective as they require fewer materials and are quicker to install than traditional doors. Additionally, they offer increased safety and security as they can be locked and secured easily. And finally, folding door systems are versatile and can be used for various applications such as dividing rooms, creating private spaces, or for creating temporary partitions. Overall, folding door systems offer a convenient and cost-effective solution for spaces that require quick and easy access.

Folding door systems are known for their slim profile sightlines, which refers to the minimal width of the frame that surrounds our door panels. This slim design allows for maximum light and views to pass through, creating an open and airy atmosphere in any space. 

Slim profile sightlines also allow for an unobstructed view of the surrounding area, making it easier to monitor activity and improving safety. Your beautiful home will open up safely to its surrounding environment.

Additionally, the slim design of folding door systems gives the illusion of a larger space, as the doors blend seamlessly into the surrounding walls. This creates an open and spacious feel, even in smaller rooms. Furthermore, the slim profile sightlines allow for a more seamless transition between indoor and outdoor spaces, creating an ideal environment for entertaining or simply enjoying the natural beauty of the surrounding area. 

The slim profile sightlines of folding door systems offer numerous benefits for both form and function, making them an attractive option for any high-end building or space.
