We recommend panel widths do not exceed 1100mm or 3000mm in height, but greater sizes than this can be achieved, please contact our technical department for advice. Operating system The folding doors (SF70) is a bottom-running system, consisting of wheels which are manufactured from tough polyamide and set around a maintenance-free sealed bearing, giving a quiet, smooth operation.

Track options There are two choices of track on our folding doors; a standard stepped track for a severe weather rated system or an aluminium flush track recessed into the floor. This provides a level walkthrough with an uninterrupted floor finish.

Furniture Handles and hinges are made of cast alloy, handles are sprung-loaded and flush-fitted to enable door panels to stack flat when fully opened. Optional lever handles are available upon request for single access door or lead doors.

Security Our bi folding Doors have a high level of security is fitted to our doors as standard; including insurance backed multi locking system. Additional locking mechanisms can be added as additional extras.

Discreet finger safe gaskets The gaskets (consisting of long-lasting EPDM) between the door panels and side jambs are continuous and have a unique chamfered design. This means that they interlock and form a highly efficient double seal.

Pull handles When the Sunflex folding door system opens externally the intermediate panels are fitted with a moulded 'D' shaped handle, this sits neatly within the gasket line enabling easy closure of the panels against the compression top and bottom gasket seal.

Ventilation Trickle vents of either 2500mm2 or 5000mm2 can also be incorporated with the addition of a 40mm add-on head profile to satisfy building regulations.
