Choosing a material

Aluminium or uPVC?

Both do a good job. Which one is right depends on how much glass you want, how the building is exposed and what the budget has to cover. Here is some of the work.

Aluminium
  • Slimmer frames, more glass
  • Powder-coated, minimal upkeep
  • Corrosion and warp resistant
uPVC
  • Excellent thermal insulation
  • Rot, rust and mould resistant
  • Noise cut by nearly 80% when double glazed
