Choose your size, panels and colour

Personalisation is at the heart of every Origin OS29 sliding door.  Choose from a range of standard colours at faster lead times.  Or there's over 150 other shades from classic tones to bold dark colours and anywhere in between. The slim mullion enhances two panels doors giving you a 50/50 opening.  Three panels doors provide a two-thirds clear opening with the panels neatly stacked together. For the threshold, it's possible set lower for a better transition outdoors, in double or triple track arrangement. For the handles, the Origin OS-44 slimline sliding doors come with two options, both functional and elegant. The integrated handle offers key and bolts unlocking within one handle unit. Or there's the option for an architectural bar handle at 500mm, long with separate locking. Both options come in high quality, marine-grade stainless steel.  


Secure, weather resistant and always reliable

Ideal for exterior patio doors, separating a conservatory, for balconies and even a room divider.

Improved security, weather protection and energy efficiency.

Enhanced security comes from the safety glass, held securely in place with Internal glazing beads.  These also prevent anyone from removing the glass from the outside. Excellent locking comes from the multi-point locking system, having six locking points. As standard, you get toughened glass units having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas.  High performance glass insulating your room and providing all-year comfort.
