Contact usFrequently Asked Questions
Are bi-fold doors secure?
Yes. Quality bi-folds are built with multi-point locking systems, strong aluminium frames and toughened safety glass. When installed correctly, they meet or exceed current security standards such as PAS 24.
Can bifold doors be used in an extension and a conservatory?
Yes, bifold doors are ideal for both extensions and conservatories. They provide a seamless connection between indoor and outdoor spaces, allow plenty of natural light, and can be customised to fit large or irregular openings

Is an aluminium bifold door better than a uPVC bifold door?
Generally yes — an aluminium bifold door is often superior to a uPVC bifold. Aluminium frames are stronger and slimmer, so they allow larger glass panes and a wider opening. They’re more durable, weather‑resistant and rigid over time. uPVC is cheaper and can suit smaller installations, but for longevity, strength, and contemporary looks, aluminium tends to offer a better long‑term result.
What U-values can aluminium bifold doors offer?
Modern aluminium bifold systems — when fitted with thermally broken frames and high‑performance glazing — can achieve U‑values around 1.4 W/m²K with double glazing, and as low as ~0.9 – 1.0 W/m²K with triple glazing, depending on size and configuration.
Do bi-fold doors require a lot of maintenance?
Aluminium bi-folds are low-maintenance. Occasional cleaning of the frames and glass, plus periodic lubrication of the tracks and moving parts, is generally all that’s needed to keep them operating smoothly.
