Aluminium Bifolding Doors
The Alunet Bifold Door slimline frame is one of the leading profiles in the UK, known for its durability and strength. This system enables the creation of one of the slimmest door frames on the market, with a frame width of just 55mm and a sightline of 120mm where two frames interlock with a gasket on 10mm. Despite its slim profile, the Alunet doors are incredibly strong. Bifold door configurations can reach up to 3000mm in height and each panel can be up to 1200mm wide. The system can even create configurations of up to 14 door panels.
The Alunet system, combined with high-quality specifications, manufacturing processes, and service standards, ensures the perfect solution to your product requirements.
Available from only £495 per panel, including UK delivery.

High-quality aluminium
Our aluminium bifolds are made using only the highest quality aluminium profiles. Strong, durable, and easily customisable, our aluminum bifolds are some of the best available today.
Affordable prices
At Prime Aluminium, we offer some of the UK’s most competitive prices on aluminium bifold doors. We always provide accurate quotes on all product orders.
Super-slim sightlines
Aluminium’s inherent strength allows for the slimmest frames capable of supporting large glass panes. This creates more glass equaling more natural light intake for a brighter interior.
Aluminium bifold doors colour choices
We keep things simple by offering three standard colours for our aluminium bifold doors: Anthracite Grey, Black, and White. There's also a standard dual colour option with an anthracite exterior and white interior. Although there are hundreds of RAL colours available, 99% of our clients choose one of these three options. We hold these colours in stock, enabling faster turnaround times.
Anthracite Grey (RAL 7016) The classic aluminium bifold door colour for that ‘Grand Designs’ look.
Jet Black (RAL 9005) Perfect for a sophisticated, contrasting colour option or a contemporary finish.
Traffic White (RAL 9016) Offers a traditional look, often chosen to match existing window frames, making it an ideal alternative.

Energy Efficient Glazing – The Right Choice
Our aluminium bifold products are installed with Low E glass as standard. Low E glass is one of the most energy-efficient glazing products in the UK. It's specifically designed to help homes reduce energy consumption and save money on energy bills. This energy-efficient glass also performs exceptionally well with the Alunet bifold door profile and our choice of hardware, making it the perfect choice for any home or commercial property.
Key Features of Low Emissivity Glass
• Energy Efficiency: Improves your home's energy efficiency by balancing thermal insulation and maximising free solar gain.
• Reduced Energy Consumption: Less energy is required to keep your home comfortable.
• Environmentally Friendly: Lower CO2 emissions due to reduced energy consumption.
• Heat Loss Reduction: The coating prevents heat from escaping through the glass, significantly reducing heat loss.
• Eliminates Cold Areas: Helps to eliminate cold spots around windows, making your home warmer and lowering energy bills.
• Reduces Condensation: Minimises condensation on the inner pane.
• Neutral Appearance: Has a neutral appearance in both transmission and reflection.
