The SF75h can be a top or bottom-running system. A bottom-running system is recommended unless it is not possible to accommodate a deeper (40mm) bottom track. The aluminium running carriage mechanism consists of four wheels, manufactured from tough glass fibre reinforced polyamide, set around a maintenance-free sealed bearing, giving a quiet, smooth operation with optimum resistance to extreme temperatures. Each running carriage and guide mechanism can carry up to 200 kilograms.


Self-lubricating collar type bearings provide quiet operation without squeaking hinges.


There is a vast range of different configurations the SF75h can be made in. The doors can either be opened to the inside or outside.

The Sunflex SF75h is manufactured from triple-laminated solid timber sections. These sections have been stabilised at stress points and bonded back together with opposing grains, which creates added strength whilst preventing warping and twisting.


Sunflex superior design ensures that when the laminated timber panels are closed they interlock, forming a solid joint that ensures maximum weatherproofing in addition to being an excellent security feature. The system has been designed in such a way to ensure there are no draughts or rattles when the doors are closed.


A high level of security is provided as standard, with an effortless, quick, smooth and easy operation. It consists of a two-point top and bottom shoot bolt mechanism, with additional central locking point to end Lead door. The locking system is incorporated within the framework within each intermediate panel, operated by an internal flush handle. The shoot bolt rods are manufactured in aluminium and linked by a corrosion resistant cam. In addition, they are capped with polyamide cones that prevent any metal damage to the tracks when locking, whilst compressing the panels tight against the top and bottom seals.



Handles and hinges are made of cast alloy; handles are sprung loaded and flush fitting to enable door panels to stack flat when fully opened. Large ‘D’ handles and automatic door closures can be fitted if required, for commercial instances. Trickle vents of either 2500mm2 or 5000mm2 can also be incorporated within the head profile.


Panel Catch

In the situation of a single access or pass door in an odd number configuration, the panel is fitted with a heavy duty adjustable panel catch which prevents the door from swinging back round in high winds and also counter weights the door with the adjacent panel for effortless operation.


Pull Handles

When the folding door system opens externally the intermediate panels are fitted with a moulded ‘D’ shaped handle this is attached to the internal hinge between two even panels and sits neatly within the gasket line enabling easy closure of the panels against the compression top and bottom gasket seal.


Design Options

The door system designs can be customised according to your preference - options includes mid-rails, mullions, plant-on bars with dummy spacer grids, arched heads, timber fillets, deeper top and bottom profiles and solid in-fill panels, among many others. Additional ventilation can be achieved by incorporating a tilt and turn window within the door panels.
