BI-FOLDING DOOR
Specification and dimensions
Slim, beautiful sightlines
• Attractive, slim-line profiles with industry leading sightlines.
• Low profile integrated threshold as standard.
• Concealed slavelock actuator for un-cluttered aesthetics (French door arrangement).
• Slim, aluminium adjustable trickle air vents, colour matched to standard colour range.
Fast & easy installation
• Patented clip-in internal glazing beads, the only aluminium clip-in bead which can be removed
quickly without damaging the paint finish. Wedge gasket not required, cutting down on installation time.
• The door is pre-assembled and ready to glaze, easy build kit-form option.
• Pre-assembled panels are fabricated using strong, bonded and crimped mitred corners.
• Well thought out packaging with compartmentalised installation parts box.
Strong and secure
• Fuhr hook locking mechanism with ‘lift-up’ to lock handle and adjustable, one-piece keep.
• 5 or 7 traffic door locking points. (2 extra shootbolts when sash taller than 2260mm)
• Yale 3 star kite-marked cylinder as standard.
• Anti-backdrive secondary shoot-bolt locking on folding doors with fibre reinforced guides.
• Low angle folding door shootbolt handle requiring only 120° of rotation. Secure even if left unlocked.
• Stainless-steel fixings, rails, hardened wheels and articulated sealed rail bearings for class leading
rolling smoothness and long life.
Thermally efficient
• Wide polyamide thermal breaks and fully thermally broken profiles and locking mechanisms.
• High performance QLon, EPDM and sealed brush-pile weather seals.

High efficiency IGU (insulated glass units)
• Unit size : 28mm (4mm glass + 20mm spacer + 4mm glass)
Various glass options including :
• Planitherm total plus
(Low-E glass, warm edge spacer, argon filled)
(SF75 U value : 1.22 Wm2/K)
• Planitherm one (Low-E Glass, Warm Edge Spacer, Argon Filled)
(SF75 U Value : 1.0 Wm2/K)
Low-E glass coatings
• Solar emissivity as low as 0.05
• Solar heat gain coefficient (g-value) down to 0.14
“Low-E coatings minimize the amount of ultraviolet and infrared light that can pass through without
compromising the amount of visible light that is transmitted. When heat or light energy is absorbed by
glass, it is shifted away by re-radiating outward from the glass surface.”
Warm edge spacer technology
• Up to 2dB lower noise transmission
• Reduced condensation by up to 70%
• Tested down to -45°C and up to 85°C
“Warm edge technology has radically changed the window market by significantly improving thermal
performance to reduce thermal conductivity, lower heat loss and improve energy efficiency.”
Specifications subject to change. Other glass options available including laminated
