More Details

AluView’s flagship aluminium bi-fold door is the UK’s top-selling choice, delivering outstanding benefits for fabricators, installers and end users alike. Our latest enhancement to the AluView bi-fold door brings even better thermal performance plus faster, more efficient fabrication and installation.

Exceptional Thermal Performance

We’ve retained the sleek sightlines and overall dimensions you know and love, while upgrading the outer frame to feature a 30 mm polyamide thermal break—over 60 % wider than the original 18.6 mm. Fitted with a 1.2 centre-pane, double-glazed unit (with foam insulation), this achieves a U-Value of 1.4 and an A energy rating, maximising solar gain and flooding your space with natural light. The new DV100 track insert clips effortlessly into place for an even smoother build.

Expanded Profile Choices

Choose from two new rebated frames (DV17 and DV19N), opt for our integrated cill or stick with the classic low-threshold option. We’ve also introduced the heritage-style DV225 sash, perfectly matching our existing range of period-inspired windows and doors.

Integrated Ventilation

Integrated 70 mm UN3570 and 82 mm UN3582 hooded trickle vents are now available as optional extras, ensuring discreet, continuous airflow without compromising your door’s aesthetic.

Enhanced Hardware & Accessories

Our hardware lineup has been overhauled to boost security and simplify stockholding:

PAS 24-Approved Roller (ACDV232): Meets the highest security standards, reducing the need for multiple roller types in your inventory.
Slimline Shoot-Bolt Gearboxes: The new locking (ACDV427) and non-locking (ACDV627) gearboxes supplant the ACDV227 and ACDV927, offering a sleeker profile.
Heavy-Duty Shoot-Bolt Handles (ACDV425/426): Swap out the standard D-handle for a minimalist shoot-bolt handle, keeping lines clean and operation intuitive.
Improved Magnetic Latches (ACDV306): Designed to hold sashes firmly in place, even in strong gusts.

With these upgrades, the AluView bi-fold door sets a new benchmark for thermal efficiency, design flexibility and on-site convenience—making it the perfect choice for your next project.
