Features & Benefits

Superior Materials

Aluminium is the strongest and most durable material we offer. Added powder coating ensures that these aluminium sliding doors are scratch resistant.

Long Lasting

Aluminium has an expected lifetime of 30 years with low maintenance for end users—five to ten years longer than most other materials, & less likely to warp.

Energy Efficient

Don’t compromise your views with poor thermal efficiency. With a thermal break, aluminium sliding doors offer U-values as low as 1.6 W/m2K.

Premium Suppliers

We establish deep ties to our suppliers at Smart and Comar, who use nothing but the strongest aluminium and trial tested glass for patio doors.

Slimmer Sightlines

Because of the material’s increased strength, aluminium sliding doors are more tensile, & hold more weight, offering slimmer sightlines for a sleeker look.


When using Window Projects, our Certass and FENSA certifications make us the perfect candidate to handle your domestic and commercial work.

Bespoke Products

Aluminium patio doors offer a great light resource for apartments and other commercial projects. They’re especially effective in tight spaces or spaces that wish for ventilation without obstruction. Furthermore, the lowered thresholds offer increased accessibility for wheelchair users or those with decreased mobility.

We can create aluminium sliding doors to almost any specification. Now, when you choose our triple glazing option, you can improve the energy efficiency of your design from an industry standard 1.6 W/m2K.

Most all of our sliding patio door designs can withstand 600 Pa air pressure, 250 Pa water pressure, and 1200 Pa wind pressure. All of our aluminium sliding doors come with polyamide thermal breaks to increase energy efficiency.

Additionally, we offer double and triple tracks for large commercial projects for two, three, or four sash systems. That way, your aluminium patio sliding doors offer the greatest ease of access.

Accessories & Add Ons

Window Projects offers large scale aluminium sliding doors, with multiple sashes if need be. We can offer automation through third parties if you’re planning a commercial project, like a showroom that needs large apertures.

Our aluminium sliding doors are fitted with multi point locking systems like security deadlock and hook bolts. These systems can be fitted to each sash for maximum security. Additionally, door restrictors can be fitted to the door at increments, depending on the application, whether in hospitals, schools, or other commercial applications.

Aluminium patio sliding doors have smaller frames than PVCu but can still be ordered in a variety of colours or woodgrain finishes for every style build. We can even supply dual colours for interior/exterior profiles. If you need, we can send you a sample.

Ask us about the glass options for aluminium sliding doors. Commercial projects may be well served by self cleaning and anti-glare glass. We also have decorative, coated, or gas filled glass.

Aluminium has a long life, lasting decades with minimal maintenance and has the least chance of warping and other wear and tear. Timber, though sturdy, can be cost prohibitive and requires constant upkeep for the end user. And it still doesn’t last as long as aluminium.

Once you give us a call or use our contact form, we can get your details to give you a quote more accurately. Aluminium is a superior material with a price that reflects its quality.

Aluminium sliding patio doors are the perfect fit in cases where there is less space, or where the door cannot protrude. For example: in commercial projects where there are showrooms, or in residential projects where there is less interior/exterior space.

Aluminium bifold doors can be used as traditional doors or pulled back to create open space between the interior and exterior.
