SF45 Technical
Dimensions
The manufacturer recommends panel widths do not exceed 1100mm with a maximum height of up to 2800mm (dependant on width). Heights greater than this can be achieved, please contact our technical department for advice. The system can cater for very large openings - up to 10 metres in any one direction.
Fixed glazing can be built above the door system. Where this is required for wider openings strengthening profiles are incorporated within the door framework to aid lateral stability.
Profile
There is a choice of profiles from the WS (softline/rounded) edge to the WE (square) edge to meet your own design requirements and to match with any conventional aluminium or UPVC systems.
Track option
There are two choices of track; a standard weathered track for a severe weather rated system or, for added convenience and improved safety, a 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.
In any exposed location we would always recommend the use of a weathered track. When used with an outward opening door a weathered track can be fully recessed below your internal floor level meaning that there is no threshold to trip over, just a step down to the outside. An external deck or paving can be brought up to the track on the outside giving a very minimal diference in levels whilst maintaining a weather tight seal.
Sunflex 45M – Versatilty from Sunflex
The Sunflex 45M is centre-mounted, giving versatility to the system that allows stacking half-in and half-out. This enables space to be evenly taken up on both sides, especially useful when space is at a premium. (For internal situations only)
Track-free Option
As the Sunflex 45M is centrally mounted, it also offers the option of being supplied without a bottom track, making it ideally suited for internal room dividers.
Security
The standard locking system offers a very high level of security with a quick, smooth and easy operation. It consists of a two-point top and bottom shoot bolt mechanism, which is incorporated into the framework within each intermediate panel. For improved security all Sunflex folding door systems are internally glazed as standard with centre secured locking hinge pins and interlocking gaskets.
Where there are an odd number of panels, a five-lever profile cylinder is fitted to the end lead door; or to the first opening pair in an even number of panels. It can be fitted to either the inside only or both internally and externally, meeting the requirements of the Association of British Insurers.
Weather seals
The Sunflex 45 system is a severe weather rated system when used with the weathered track option, providing a top and bottom double-rebated seal. Unique double gaskets are finger safe and eliminate draughts. (The system achieves DIN 18055, Category B performance for wind loading and water leakage.)
The gaskets (consisting of long-lasting EPDM) between the door panels are continuous and have a unique chamfered design. This means that they interlock and form a highly efficient double seal, providing the system with three distinct advantages:
Operating System
The system is available either top running or floor mounted. The running mechanism consists of wheels manufactured from tough polyamide and set around a maintenance-free sealed bearing, giving a quiet, smooth operation with optimum resistance to extreme temperatures. Each wheel and guide mechanism can carry up to 200kg. The wheels of the running mechanism run in a channel in the sides of the track rather than sitting directly on the bottom, unlike many inferior systems, minimising the risk of the operating system fouling should any dirt or debris be allowed to build up in the bottom of the track.
The unique design of running gear mechanism hinged between the door panels eliminates the need for a sliding post. This achieves smoother operation, slim sightlines and larger glass area. In addition, self-lubricating collar-type bearings guarantee a quiet operation without any squeaking hinges.
Appearance
The Sunflex 45 system is available as standard in Silver Anodised EV1 or polyester powder coated to a semi-gloss finish; White RAL 9016, Aluminium RAL 9006, Grey Aluminium RAL 9007 or Anthracite Grey RAL 7016. All handles are specially designed to complement the door system; standard colours are White RAL 9016, Black RAL 9011, Aluminium RAL 9006, Grey Aluminium RAL 9007 or Anthracite Grey RAL 7016. Gaskets are in Black, with hinges mounted within seal sightline available in White RAL 9016 or Black RAL 9011.
Other RAL colours are available with over 200 colours to choose from. One can even have different colours to the inside and outside (dual colour) or different wood grain effects are available for a nominal charge. The RAL colours can be applied to the handles and hinges if required or alternatively there is a stainless steel handle option. In addition you can specify whether a matt, semi gloss or full gloss level of paint finish is required. A Marine environment finish, required to all systems within 5000m of a shoreline or chemical swimming pool environment, is also available.
Customised
Designs can be customised according to your preference - the options include mid-rails, mullions, plant-on bars with dummy spacer grids, among many others.
Complete System
The SF45 system can also be used to manufacture single doors, French doors, pocket sliders, tilt and turn windows and fixed glazed screens. Sunflex uses matching profile sections for these products to achieve an aesthetically uniform appearance throughout.
Glazing
The system is internally glazed and can accommodate glazing ranging from 4mm clear toughened glass up to a sealed unit of 28mm. All units are BS kite-marked, manufactured to BS6206A and BS5713 standards.
IDSystems offer a wide choice of glazing options, including manual or electrical internal venetian or pleated blinds which can be incorporated inside the glazed unit. These are very popular, especially on internally opening systems where curtains are not practical.
