Sunflex SF75h - Timber Folding Sliding Doors
Elegant, classic and sympathetic to preservation areas the Sunflex SF75H timber folding sliding door boasts the slimmest sightlines in Europe. The Sunflex SF75H folding sliding door is commonly used for external and internal application on domestic and commercial projects including, private extensions, Patio or French door replacement, conservatories, bars, restaurants, swimming pool enclosures, luxury houses and self build projects. No matter where the application the SF75H will be at harmony with nature.
Manufactured using engineered timber sourced from sustainable forests the SF75H is available in Nordic pine (knot free), Meranti (hardwood) or special timbers such as European Oak. The natural beauty of the timber is enhanced with a quality factory finish. Techniques which have been mastered over many years are used to provide a high quality finish comparable to that of fine furniture. No other system looks or performs like it.

The natural character of wood is perfectly preserved using water based Sikkens micro-porous wood stains (i.e. they contain no harmful solvents) in a selection of stain colours. Alternatively the timber can be paint finished to any RAL colour (over 200 RAL colours available). The SF75H can also be finished with a dual colour, for example a wood stain finish internally and RAL paint finish externally. All Sunflex timber door systems are supplied fully finished. The standard factory finish consists of one basecoat and two topcoats with other finishes are available upon request. Each section of timber is individually dip treated, ensuring equal coverage over all surfaces, protecting the timber against rotting and water penetration. The pigmentation in the treatment protects the timber against discoloration and ultra violet rays.
The handles are specially designed to complement the door system; standard colours are Brown, Black RAL 9011 or White RAL 9016. None standard Stainless steel feature handles are also available. Minimal cushion finger safe gaskets are available in Brown, Black or White, with hinges mounted within seal sightline available in Brown, Black RAL 9011 or White RAL 9016. The hinges and handles can also be supplied to match the special RAL of your choice. Download the finishes page for more information.
The Sunflex SF75H is manufactured from engineered timber. Triple laminated, the sections of timber have been stabilised at stress points and bonded back together with opposing grains for greater strength and durability.
Even with the profiles constructed from multiple sections of timber the Sunflex SF75H offers the slimmest sightlines in Europe.
Available with two choices of track, the standard stepped weathered track for severe weather rating or the flush track for added safety and convenience. The aluminium flush track can be recessed into the floor to provide a level walkthrough with an uninterrupted floor finish, compliant to Building Regulations Doc M for disabled access.
As standard the doors provide a very high level of security, with an effortless, quick, smooth and natural operation. It consists of a two-point top and bottom shoot bolt mechanism with additional central locking point to the end Lead door. The locking system is incorporated within the framework of each intermediate panel and operated by a specially designed 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 twin seals.
A five-lever Euro profile cylinder key lock, approved by the Association of British Insurers with handles is also 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. Again as a bespoke system these can be fitted to either the inside only or both internally and externally as required. 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 minimal and symmetrically the same.
Locking hinge pins & internally glazed - For further improved security the entire range of Sunflex folding sliding door systems are internally glazed as standard, with external centre secured locking hinge pins and interlocking panels.
Optional added security - Where required additional cylinder key locks can be added at every intermediate handle point for higher security. Mortice locks can also 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. As well as providing a latching position this also offers the additional benefit of multi-point locking throughout the height of the system. Panic locks can be fitted for fire escapes, etc. Sunflex also offers electric latch release locks and roller ball latch locks for commercial use.
The minimal double gasket seals between the door panels are continuous and of superior quality (consisting of long lasting APTK). The bubble shaped gaskets are finger safe, providing a cushion to minimise the effect if fingers were to be trapped whilst also providing a compressed weather tight seal when closed. The superior design of the Sunflex folding sliding door ensures that when the panels are closed they interlock, forming a solid joint that ensures maximum weatherproofing. In addition the interlocking timber panels double up as 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.
Weathered track - (for severe conditions) creates a severe weather rated system by providing a triple-rebated perimeter seal (The SF75H system achieves DIN 18055, Category C performance for wind loading and water leakage.)
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.
The SF75H can be a top or bottom-running system. 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. The self lubricating collar type bearings provide a quiet operation without squeaking hinges.
Both the handles and hinges are made of cast alloy. The handles are sprung loaded and specially designed to be 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 5000mm2 or 2500mm2 can also be incorporated within the head profile.
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 - each door system can be customised according to your preference and design specification. Options includes mid-rails, transoms/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 SF75H 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 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.
