folding doors

sfk69 specification and details

SFK69 folding sliding doors create an open, flexible and modern space for both living and working environments. An ideal solution for sunrooms, conservatories & swimming pools. Also ideally suited for commercial situations including pavement cafés, restaurants, balconies and car showrooms.

Manufactured in knot free Pine, Meranti or European Oak, the system blends beautifully into environmentally sensitive areas offering unequalled views to the outside world.

Door sets can even be manufactured to slide around segmented 'curves'!

SFK69 doors comply with revised (April 2006) part of Document L Building Regulations.

Dimensions

Panels up to 2800mm high can be hinged together in long 'trains' to open up 90% of an elevation. The maximum panel width is 1100mm (for heights up to 2500mm). Panel heights over 2500mm will require a horizontal transom in each panel for stability.

Security

Intermediate panels joints are held securely by internal shoot bolts top and bottom. These are operated via a flat sprung handle. End panels and pass doors are fitted with a 3-point locking mechanism that meets insurance companies' requirements.

Weather seals

Unique 'finger safe' severe weather rated (to DIN18055 groups B & C) weather seals ensure draft free year round comfortable living. The SFK69 has been pressure tested to a force 900Pa which is the highest end of the Beaufort scale. The seals are specifically designed to be soft &'finger safe' should little hands get trapped!

Appearance

Triple laminated timber frames are designed to be stable and are always factory primed. We then further factory finish them in Sikkens exterior wood stain or white micro-porous paint. The standard stains are Light Oak, Dark Oak, Teak, Mahogany & Walnut - other stains are available on request.

Glazing

Sealed glazed units up to 40mm can be accommodated in the SFK69. Our standard 24mm unit comprises two panes of 4mm clear toughened glass with a thermally efficient, argon gas filled 16mm cavity. The inner pane is equipped with a thermally efficient Low E coating. Units are manufactured to BS6206a and BS5713. Many solar control, tinted glasses and self-cleaning options are available. We can also offer Venetian or pleated blinds in a variety of colours which sit within the glazing cavity - please see "http://www.pellini.net/ for further information.

Stacking / Folding

Panels can be stacked inside or outside of the room, to the left, right or split to stack on both sides. Where odd numbers of panels are used, the last panel in the 'train' is furnished as a secure pass door with lever handles both sides for daily use.

Suspension

Panels can be top hung (suspended) or bottom rolling (floor supported). The bottom track can be recessed into the floor allowing an uninterrupted flush finish (and meets requirements of Document M).

Corner Posts

Static & sliding corner posts are available in triple laminated timber to complement the system.

Ancilleries

Transom rails and solid timber (non-glazed) panels can be incorporated into your door design.

Ventilation

Ventilation can be offered in 3 ways;

Through frame vents, where a trickle vent is placed within an "add on" section along the head track of the doors - see http://www.rwsimon.co.uk/ttfslimline.htm for further information.
In-glazed vents, which are situated above the glass at the head of the panel - see http://www.rwsimon.co.uk/airstrip_300.htm for further information.
Tilt turn panels are also available in inward opening 'trains' of panels. These do affect the appearance of the door set as there is a heavier sightline around the tilt turn panel.

Windows

We can offer tilt turn or fixed windows to complement our system.

Opening in tilt and turn windows offer multi-functional use through one single operating handle. When the handle is moved to the "tilt" position the vent opens in at the top allowing a source of ventilation. When the handle is moved to the "turn" position the window is hinged on either left or right and opens to the inside for an unobstructed view, complete ventilation & to make cleaning easy.

Tilt turn windows also comply with the Scottish Building regulations that state, "Any window or part of a window more than 4m above the adjacent ground should be constructed so that its internal and external glazed surfaces can be cleaned safely from inside the building".

Installation

We offer a full surveying and installation service nationwide. Our surveyors are qualified to discuss details of your building design, and our installers are all fully trained by us to the highest standards.
