Supplied by Lincolnshire Bi-folding Doors in Lincoln, the Origin OS29+ aluminium sliding door combines refined aesthetics with impressive strength, delivering a contemporary, reliable solution for modern homes across Lincolnshire.
Create smooth connections between indoor and outdoor spaces with our premium aluminium sliding door system. Engineered to maximise natural daylight, the OS29+ opens up uninterrupted views while operating with exceptional ease. Its slimline frames contribute to a bright, open atmosphere without compromising thermal efficiency.
Select from three precision sightline options – 77mm, 44mm, or the ultra-minimal 29mm. The 29mm configuration allows panels to stack flush, delivering a cleaner finish alongside enhanced insulation performance.
Smooth, Effortless Sliding Action
Move beyond conventional sliding systems. The OS29+ operates on a carefully engineered track that delivers a consistently smooth, lightweight glide, even when supporting large expanses of glass.
Built to the same structural standards found across the Origin range, these doors accommodate substantial glazing sizes while maintaining long-term reliability and ease of operation.
Made for Your Home – Fully Bespoke
Every property is different, which is why each sliding door from Lincolnshire Bi-folding Doors is manufactured to order.
Our experienced team in Lincoln will guide you through size, configuration, and finish options to ensure the door complements both your home and lifestyle. Every component can be tailored, resulting in a precise, made-to-measure installation.
Find Your Ideal Colour Finish
With a choice of over 150 RAL colours, there’s a finish to suit every architectural style. From understated neutrals to striking statement tones, your door can be customised to match your vision.
Each frame receives a durable powder-coated finish, designed to resist fading and maintain its appearance for years to come.
Advanced Home Security
While aluminium offers inherent strength, the OS29+ goes further with comprehensive security features. Every door includes a sophisticated multi-point locking system with at least six locking points.
In addition, the glazing is securely bonded to the frame, significantly increasing resistance to forced entry and enhancing overall protection.
High-Grade Aluminium Construction
Strong yet lightweight, these sliding doors are manufactured using premium-grade aluminium chosen for its durability and structural performance.
Designed to withstand weather exposure without warping or deterioration, the frames are supported by a 20-year guarantee, with 10 years on the glazing, offering lasting reassurance.
Thermally Efficient Design
The OS29+ incorporates advanced low-emissivity glass, featuring an invisible coating that reflects internal heat back into your home.
A built-in polyamide thermal break further improves insulation within the door profile. Together, these elements help stabilise indoor temperatures, reduce energy usage, and maintain comfort throughout the year for homes across Lincolnshire.
