Durable and slimline aluminium profiles come with a built-in thermal break with a mechanical construction.  All the sliding door components come hidden in the frames retaining the sleek and minimal proportions of the doors.  At the same time, the doors offer one of the smoothest, lightest and quietest slide actions even with the largest door panels.  Our slimline sliding doors come with high security locking systems, durable seals and built for daily use.  

The design of the doors allows these to be used for panoramic sliding glass walls and where you want to make the most of your views, available glass sizes and natural daylight. We also offer the Origin OS-44 model giving a more traditional look with similar thin proportions.

Product Features


Every aspect of these highly engineered doors is designed to provide smooth-running sliders designed to enhance and protect your home. The clever carriages beneath each panel have self-levelling properties keeping the panels consistent whether they are sliding open or closed. Even the door handles are designed to sit flush to the frame and not project outwards like conventional sliding doors and also function to lock and unlock your doors.

The locking system is designed for the product, concealed where possible to make the doors look better in the open position and help to give these doors their near frameless appearance. Every component comes rigorously tested and quality checks - just one of many reasons why these doors come with an industry-leading 20-year guarantee for the hardware and components. This includes seals, gaskets running gear, locks and levers.

Our slimline sliding doors come with a professionally applied powder coated finish, to stringent industry standards by approved and certified applicators. Therefore you benefit from a low-maintenance durable finish in over 150 RAL colours on offer.

Black and grey are by far the best colours working with the slimline nature of these doors and complementing modern architecture. Used in the window and door sector for over forty years, modern polyester powder coating not only offers the biggest choice of colours but also the best level of protection for the aluminium profiles.

Energy Efficiency

Creating a wall of light doesn’t have to mean increasing your heating bills. In fact, all of Origin’s doors are thermally broken, so the transfer of heat between the inside and the outside is significantly limited, delivering a space that’s cool in the summer, warm in the winter, and can be enjoyed all year round.

Low-emissivity glass having a Low-E coating reflects heat back into the room. This glass comes as standard in this slimline door with toughened glass units. Unlike other doors, the glass has a special silicone seal, bonding it structurally to the frame. As a result, safety, security and energy efficiency is excellent.

These doors surpass current Building Regulations with an impressive 1.4Wm2K U-Value.
