Trade Aluminium Window Systems Supplier | Altegra

Aluminium Windows

Aluminium has often been the material of choice for commercial properties; it is now becoming the preferred material of choice for windows and doors in the retail sector. Sleeker than PVCu and easier to maintain than timber, the natural strength of aluminium means larger spans of glazing can be supported in much slimmer frames.

Our aluminium windows offer the best of both worlds, combining style with substance. Helping to perfectly frame your views and bathe living spaces in natural light, our aluminium windows also offer exceptional acoustic and thermal performance to enhance the look and feel of any type of property.

  • Save money on your heating bills
  • Help reduce external noise pollution
  • Future-proof by improving energy-efficiency
