Why aluminium doors
Big moving panes of glass are heavy, and the material carrying them decides how the door looks and how long it keeps running smoothly. Aluminium takes the weight on frames a fraction of the width uPVC would need. The panels glide on engineered rollers, the powder-coated finish stays put, and a thermal break in the profile keeps the warmth on the right side of the glass. That’s why nearly every bifold and big slider we fit is aluminium.
