UPVC Sliding Doors

Whether you are searching for a brand-new patio door to improve access to your garden, or you require a new replacement inside door, you will be surprised how distinctive our new uPVC sliding door line is compared to other sliding doors on the market.

Often seen as an alternative option to bifold doors, The uPVC sliding patio doors boast an ergonomic design with an easy opening mechanism and smooth noiseless motion glide. They also feature an advanced "air glide" mechanism, that is effortless to use by family members of any age and ensures a flawlessly balanced motion along its track.

We supply standard white PVC sliding doors as well as a part q compliant option.


The PVC sliding doors boast Liniar’s patented ModLok modular locking mechanism, which is built into their frame, delivering unrivalled strength. The system includes eight mushroom head locking points built within an aluminium box-section, offering extra rigidity and strength. They also have a PAS 24 security rate, meaning that you do not have to worry about break-ins.

For additional protection, you can pick the latest anti-snap locking cylinders, that have a 3-star security rate.


Unlike traditional sliding doors, which have a four-wheel mechanism system made of steel, our plastic sliding doors have an eight-wheel system that offers a smooth ‘air glide’ without making any noise.

They are also rigorously tested to make sure that they not only meet but surpass the relevant British Standards for weather performance. The doors are made to withstand the harshest winter weather while also enhancing the perfect summer environment.


The multi-chambered profile helps to break up tiny convection currents and trap warm air pockets. This means that compared to other systems, Liniar sliding patio doors will keep more heat inside your house.


As opposed to many patio doors, our range does not require any treatment or painting to preserve its sleek and modern appearance. All you need to do preserve their look is to occasionally wipe the doors down with soapy water.

Moreover, the doors are supplied with a 10-year frame guarantee, so you can rest assured that the colours will not fade with time.


The sliding uPVC doors are made to level themselves even over uneven ground, making them exceptionally easy to install. Additionally, they can support glazed pane loads of up to 120 kilos per sash.


The doors not only provide security and efficiency, but they also boast a classy appearance. They have ultra-slim sightlines which guarantee you enjoy an abundance of natural light in your space.
