Various glazing options available with the OS-29 and OS-44 sliding doors

As the OS-29 and OS-44 do not come as a bonded system with the glazing already integrated, so there is more flexibility in what glass can be used. Whether that be laminated, toughened, or reflective - the choice is all yours. So we at the Bristol Bifold & Sliding Door Company will be able to advise on the best option for your project.

Maximise on natural light with these configuration options

The OS-29 and OS-44 ranges are available in door sets with up to six panels. It has a maximum panel size of 2000mm wide and 2520mm tall. Depending on your aperture opening, you can certainly maximise on natural light. With different configurations to choose from, there is a door that will suit your access needs, whether that’s through the middle with our four panel configuration (OXXO), or having both doors as an access or exit point with our 2 panel configuration (XX).

Sliding Doors that bring security to your home

A safe and secure aluminium sliding door from Origin

Made from a high grade aluminium, the Origin Patio Slider allows for a practical and elegant solution, without any compromise on security or performance. Extremely strong, yet weighing two-thirds less than steel, Origin’s premium grade aluminium creates the perfect balance between being visually breathtaking and structurally secure.

Color Palette

Over 150 available colours - so much choice

An almost limitless choice of colours can be applied to the aluminium frame for your sliding doors, including popular colours for the OS-29 and OS-44: Athracite grey, Slate grey, Jet black, Hipca white, Black grey and Silver metallic. This makes aluminium the perfect material for matching existing frames or making a bold design statement.

Handle options for your sliding patio door

The perfect finishing touch to your Origin Patio Door - take your pick from a combined 300mm all-in-one handle and lock featuring a thumb-turn, a 500mm stainless steel offset bar handle or a traditional Patio handle.


Stay warm when it’s chilly, cool when it’s hot outside & lower your energy bills

Just like the OS-20, every OS-29 and OS-44 is 'thermally broken', as it’s manufactured with a polyamide thermal break. This is designed to drastically reduce heat transfer through the system from one side of the door to the other, which regulates the temperature and means that the living space can be enjoyed no matter the season.
