Integrate the indoors and outdoors

With a minimum sightline of only 42 mm, MHB folding doors extend your home or office to the outdoors. They combine the strength and outstanding insulation properties of the SL30-ISO® thermally broken steel profile system. They guarantee comfort and an abundance of natural light inside.


Maximum useability

You decide how your folding door opens. Do you want it to open toward one side, both sides, or asymmetrically? We have folding doors for all kinds of spaces, small and large. All our folding door systems include a standard entry for quick and easy access without interrupting the folding door design.

High quality components

Our folding doors include stainless-steel floor and ceiling rails that allow you to slide them open smoothly, no matter the size. The upper rail carries the weight of the panels, and the bottom rail ensures perfect alignment of the panels. The secure locking system keeps out dust, rain, and cold.

Immense dimensions

The innovative SL30-ISO® profile system and the power of steel allow us to craft exceptionally large folding doors. The dimensions of any standard panel can be up to 1 by 3 meters. All of MHB’s glass finishes are available for our folding doors, offering you genuinely unique panel combinations.
