Sliding Patio Doors

For large glazed apertures

Our patio doors are highly adaptable and suitable for use as dynamic residential doors that maximise light and provide stunning views, or as sliding commercial entrances, where large opening apertures are required.


They are designed to combine strength and performance while being visually striking. Utilising double and triple track outer frame options, many configurations using two, three, four and six panels can be specified to best suit your requirements, maximising the potential to bring light & space to any property. The option of lift and slide is now also available. Fabricated to order in both single and dual colour in a wide choice of standard and non-standard finishes including textured.



Sliding Patio Doors are a great alternative to french doors, as well as being a simple and cost-effective alternative to Bifolding Doors. Our aluminium patio doors are designed to be secure and aesthetically pleasing and are available in over 200 different RAL colour finishes. We have competitive prices and all our products are made to measure and manufactured to your exact specifications.


Our Visoglide sliding patio doors are constructed from profiles with a thermal break. Robust sections enable the creation of large passageways, providing maximum natural light and panoramic views. Moveable panels sit within an outer frame and slide to the left or right.


The system offers flexibility in terms of the possible combinations of folding elements and opening sashes. Visoglide is available in a huge range of powder-coated paint colours and finishes, including dual colour, realistic wood structure, and metallic paint options. All paint finishes are produced to the highest standards.


High-Performance Double Glazing

Our aluminium patio doors can be supplied with energy-efficient 1.1 U-value Staycool solar control double glazing which helps block UV rays and solar gain whilst retaining your valuable heat in the winter. Alternatively, we can provide 1.2 U-value argon-filled low e glass for installations where solar protection is not required.



Handle Options
A selection of handles are available to make the most of your new sliding patio doors. Popular choices include luxury ‘D’ handles or a simple twist lever handle that doesn’t intrude into the visible glass area.


Trickle Ventilation
If trickle vents are required a frame extender will be required for fitting on top of the outer frame head. For a dual track door the height of the extender is 20mm and for a triple track patio the height is 42mm.
