Dualfold offers maximum opening with minimum intrusion, in a smooth sliding folding action, coupled with the same slim sightlines and true dual colour options as the rest of the Dualframe range. Dualfold is designed to carry the weight of the panels on high strength stainless steel bottom wheels, allowing the top rollers to guide the panes as they slide. This reduces the reliance on the lintel above and thus enhances the smooth sliding action.
Easy-glide stainless steel wheels not only offer smooth operation but are also totally obscured from view once the door is closed, whilst the standard Dualframe outerframe means that floor coverings can be fitted right up to the cill making the visible threshold height very low.
Dualfold features proven door hardware with a Eurogroove multipoint locking system. This means that Dualfold can be fully operated from outside as well as inside.
From three to seven pane, open in or out door sets are available. Doors can be designed to slide either to the left or right to suit the project requirements
