The SF65/68 systems are classic, stylish and elegant whilst also sympathetic to preservation areas. All timber used is sourced from sustainable forests and manufacture in one of the most eco-friendly factories in Europe. Available in a number of quality timbers, from the standard range such as nordic pine (knot-free softwood) and meranti (hardwood) to timbers available by special request such as solid oak and mahogany. All are available in an extensive range of RAL colours and wood stain finishes. The SF65/68 has superior thermal qualities.
APPEARANCE
The natural character of the wood is perfectly preserved using high performance micro porous wood stains (i.e. they contain no harmful solvents) in a variety of colours. Or alternatively the timber can be finished to any RAL colour and can also be supplied with a dual finish, for example clear lacquer internally and White RAL 9016 externally. As standard our folding sliding doors are supplied fully finished, consisting of one base coat and two top coats, other finishes are available upon special request. Each section is individually treated ensuring equal coverage over all surfaces, protecting the timber against rotting and water penetration.
All ironmongery is manufactured from cast alloy and specially designed to complement the door system and allow the panels to stack flat when fully opened. Handles are supplied in the standard colour range of Brown RAL 8077, White RAL 9016 or Silver RAL 9006 or available in any RAL by special request. Gaskets are available in Brown, Black or White.
PROFILE
The SF65/SF68 systems offer the slimmest sightliness in Europe. Using the process of lamination for greater strength and durability, the timber is separated into three solid sections and then bonded back together with opposing grains to ensure a lifetime of continued usage and reliability with minimum framework.
CONFIGURATIONS
For an indication of how the doors operate and to view the possible panel configurations please see the Sunflex Configuration page.
TRACK OPTIONS
Both systems are available with two choices of track, the standard weathered track for a severe weather rated system or for added convenience, safety and compliance with Doc M of the building regulations for disabled access an aluminium flush track which can be recessed into the floor.
SECURITY
For improved security all folding sliding door systems are internally glazed as standard with centre secured locking hinge pins and interlocking panels as well as the below security features;
Shoot Bolts:
A high level of security is provided as standard, with a quick, smooth and easy operation. Incorporated into the frame profiles at each intermediate panel a three point shoot bolt mechanism is operated with a flush internal handle. When operated the doors become compressed tight against the weather seals providing a severe weather tight system.
Five-Lever Key Locking Cylinder Incorporated Within The Profile:
A five-lever Euro profile key lock and handles are integrated into the existing profile ensuring all sightliness remain symmetrical. 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 to the inside only or both inside and outside as required, meeting with the Association of British Insurers.
Internally glazed and locking hinge pins:
For improved security all Sunflex folding sliding doors are internally glazed as standard, with external centre secured locking pins and interlocking gaskets.
Added Security:
Additional security options such as mortice locks and extra cylinders are available. Please contact us for further details.
WEATHER SEALS
The Weathered Track For Severe Conditions:
A severe weather rated system is achieved with the weathered track option providing a perimeter triple-rebate 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 nylon brush piles separated by a twin fin seal, giving an effective seal. We recommend that some form of sunken drainage and slope away from the doors is integrated with this option.
Gasket Seals - Finger Safe Cushion Gaskets:
The double gasket seals between the door panels are continuous and made of superior quality, consisting of long lasting APTK internally and interlocking EPDM gaskets externally. An added quality of these bubble gaskets is that they are finger safe and child friendly, providing a cushion to minimise the effect if fingers were to be trapped. These gaskets have been cleverly designed to interlock when the panels are closed ensuring maximum weatherproofing, added security and no draughts or rattles when the doors are closed.
OPERATING SYSTEM
The SF65 can be a top or bottom running system. A bottom running track is recommended unless it is not possible to accommodate a deeper (40mm) bottom track or when panel heights exceed 2500mm. With either operating system the aluminium running carriage consists of four wheels, manufactured from tough glass fibre reinforced polyamide, set around a maintenance free sealed bearing. Each carriage has self lubricating collars to provide a smooth, quiet operation and can effortlessly carry up to 200kg.
GLAZING
All panels are supplied as standard - factory glazed to a high specification, comprising of 4mm clear toughened Low E soft coat glass to the inner pane - 20mm cavity - 4mm clear toughened glass outer pane to exceed building regulations for safety BS6262 and thermal efficiency. Guidance will be provided should you be unclear on your requirements.
TRICKLE VENTS
Tickle vents of either 4000mm2 or 8000mm2 can be incorporated within the head profile.
DESIGN OPTIONS
Amongst many other options we can customise our folding sliding door systems with mid rails, mullions, plant on bars, dummy spacer grids, arched heads, deeper top and bottom profiles and solid infill panels.
Park Farm design also manufacture and supply additional bespoke joinery items such as sub cills and cover trims to your specific design requirements.
