Demand for large expanses of glazing has continued to grow, and homeowners are seeking brighter interiors, uninterrupted views, and seamless transitions between indoor and outdoor spaces. For installers working with aluminium, this trend presents an opportunity.

Sliding Doors that combine contemporary aesthetics with an industry-leading performance gives installers an advantage in a competitive market.

The latest development in this space from Origin is the OS29+ sliding door. As the next generation system, it’s designed to offer an enhanced security and thermal performance alongside an elevated design.

Aluminium has long been valued within the industry for its ability to offer flexible design solutions. With an exceptional strength to weight ratio, it can offer large maximum sizes, slim profiles and optimal security.

At just 29mm, the OS29+ delivers the slimmest sightline option within Origin’s sliding door range, and this maximises the glass area and natural light coming into a home while maintaining the structural benefits of aluminium.

Aesthetically, the OS29+ has been refined to offer a sleek contemporary finish that complements both modern architecture or more traditional properties. For installers working across a range of project types, flexibility remains key.

However, its slim design alone is no longer enough. With an increasing focus on energy efficiency, thermal performance has become a critical factor in product selection. The OS29+ has therefore been engineered with enhanced thermal efficiency. By incorporating an advanced thermal break that reduces heat transfer, it’s able to achieve a U-Value of 0.78 W/m2K.

This gives installers the ability to offer a visually striking sliding door solution that also supports the wider renovation shift that focuses more on sustainability and energy efficiency. For installers, the ability to demonstrate strong thermal credentials alongside premium aesthetics can be a key differentiator at point of sale.

On top of energy efficiency, homeowners are also increasingly prioritising security. Therefore, the OS29+ comes with a multi-point locking system and is PAS 24 accredited.

As with all Origin systems, the OS29+ is fully bespoke. From size and configuration to colour, finish and hardware options, installers can specify a solution that meets the precise needs of their client and the property itself.

The OS29+ is available with a stunning and highly sought-after Signature knurled handle. This Signature knurled design language can be seen across the rest of the Origin Home Collection, offering installers the ability to provide a cohesive and holistic aesthetic to their client.

As a further differentiator, the OS29+ is powder coated at our in-house, state-of-the-art 55,000ft2 facility. Taking a fresh approach to the powder coating process, we were able to achieve Qualicoat and Qualicoat Seaside in record time. This offers installers clients a flawless finish that they can enjoy for the long term.

Practicality and ease of use have also been central in the OS29+ design process. The system is engineered for smooth, effortless operation, with door sashes gliding along a concealed track that can be recessed into the floor for a flush, ultra-sleek finish – offering a seamless indoor-outdoor living experience.

The full Origin product range is manufactured in the UK using premium aluminium and consists of bi-fold, sliding, French, single, front and internal doors and windows. For the trade, aluminium continues to represent one of the most versatile and future-proof materials in the fenestration market.

As the market continues to evolve, products that balance aesthetics, performance and practicality will remain in high demand. The OS29+ demonstrates how next-generation aluminium sliding doors can deliver on all three, giving installers the opportunity to provide solutions that are not only visually impressive, but are built to perform.
