ALL TIMBER IS SOURCED FROM SUTAINABLE FORESTS
The standard timbers are Meranti (hardwood) and Nordic pine (knot free-softwood), while other timbers such as American White Oak or European Oak are available by special order. The natural beauty of the wood is enhanced by our finishing techniques, resulting in the product being comparable to that of high quality furniture, no other system looks like it or can perform like it.

At harmony with nature, the SF65/SF68 folding door is suitable for all internal and external applications, for domestic and commercial use, including living room extensions, French or patio door replacement, conservatories, sunrooms, balconies, bars, restaurants, shop fronts, swimming pool enclosures and particularly, coastal locations.

PROFILE
The Sunflex SF65/SF68 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.

TRACK OPTIONS
There are two choices of track: a standard stepped weathered track for a severe weather rated system or for added convenience and improved safety, an aluminium flush track recessed into the floor. This provides a level walkthrough with an uninterrupted floor finish, compliant to Doc. M of the Building Regulations for disabled access.

SF65M – MIDDLE FOLDING OPTION
The Sunflex SF65M is centre-mounted, which enables the panels to stack half-in and half-out so the space is evenly taken up on both sides; especially useful when space is at a premium.

SECURITY
Shoot bolts
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.

Five-lever key-locking cylinder incorporated within the profile
A five-lever Euro profile cylinder key lock and handles are fitted to the end lead door or single pass door where there are an odd number of panels, or to the first opening pair, in an even number of panels. These can be fitted to either the inside only or both internally and externally as required, meeting the requirements of the Association of British Insurers. By integrating the locking cylinder into the existing profile in this way eliminates the need for an additional add-on profile familiar with other sub standard systems, ensuring all sightlines remain symmetrically the same.

Added security options
Additional key locks can be added at every intermediate handle point for higher security. Mortice locks can be fitted where a latching position is required for added convenience. As an alternative to mortise locks, a multi-point ESPAG lock can be fitted. This offers the additional benefit of multi-point locking throughout the height of the system as well as providing a latching position.

Panic locks can be fitted for fire escapes, etc. Sunflex also offers electric latch release locks and roller ball latch locks for commercial use.

Internally glazed and locking hinge pins
For improved security all Sunflex folding doors systems are internally glazed as standard, with external centre secured locking hinge pins and interlocking panels.

WEATHER SEALS
The weathered track for severe conditions
A severe weather rated system is achieved with the weathered track option providing a perimeter triple-rebated seal (The system achieves DIN 18055, Category C performance for wind loading and water leakage.)

The flush track
The bottom seal between the door and the flush track is via double, twin nylon brush piles separated by a twin fin seal, giving an effective seal. It is recommended that some form of a sunken drainage channel and a slope away from the doors be integrated, to avoid any pooling of water.

Minimal finger safe cushion gaskets
The double gasket seals between the door panels are continuous and of superior quality (consisting of long lasting APTK). These bubble gaskets are finger safe, providing a cushion to minimise the effect if fingers were to be trapped.

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.

OPERATING SYSTEM
The SF65 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.

FURNITURE
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.


The SF65 system can also be utilised to manufacture single access doors, French doors, tilt and turn windows and fixed glazed screens. Also available is the new ‘Pocket’ Sliding’ door and the ‘Parallel Sliding Tilting’ door (PST), which enables one panel to tilt inwards and slide on a mono track behind a fixed panel. Using matching profile sections enables you to achieve an aesthetically uniform appearance throughout. In addition, fixed glazing can be built above the folding door system. Where this is required for wider openings, strengthening profiles are incorporated within the door framework to aid lateral stability.
