Janisol Folding doors

Janisol folding doors are based on the Janisol insulated system and have a multitude of applications. They can be used as a room divider or to provide access to exterior space. The proven system, developed specially for flexible openings, can be used for inward- or outward-opening doors. Ultra-slimline steel profiles and narrow face widths result in robust, resilient and durably strong folding doors.
