Premium Folding Doors

Our aluminum windows and doors put the finishing touch on luxury real estate, built to order in our Palm Desert manufacturing facility. While our sliding systems offer unparalleled views, the 4510 Series Premium Folding Door Systems redefine versatility for indoor-outdoor living.

Engineered with a revolutionary bottom-weighted design, the 4510 Series eliminates the need for heavy structural headers, making it an ideal solution for both new builds and complex remodels. These systems maximize space efficiency and energy performance without compromising on the slim-line aesthetics Monumental is known for. Whether configured for a private patio or a grand transition to a pool deck, our folding doors provide a professional, seamless finish you won’t find anywhere else.
