Bespoke 6 Panel Bifold (3 Transom)

Our slimline aluminium bi-folding doors with transoms have been meticulously designed to cater to diverse budgets and tastes, offering unparalleled strength, durability, and aesthetic appeal. Crafted from premium-grade aluminium, our bi-folding doors boast a sleek and minimalist design that doesn't compromise on robustness or practicality. Lightweight yet incredibly strong, aluminium facilitates the slimline profile of our doors, making them easy to manoeuvre and virtually maintenance-free.

Our aluminium transom bifolds feature slim thermally broken profiles, ensuring expansive views and optimal thermal performance. With glass accounting for 80% of the surface area, we prioritise glass specification to enhance thermal efficiency. Experience unrivalled insulation and comfort with our advanced polyamide thermal barrier technology. This innovative profile technology creates a barrier between the external elements and your interior, retaining heat, reducing condensation, and buffering against external noise.

Quality, compliance, and security are non-negotiables for us. That's why we manufacture and assemble all our products in the UK, utilising state-of-the-art machinery and highly qualified staff to ensure perfection with every door that leaves our factories. Tailored to your specifications, our doors can be customised to fit your unique requirements.
