Why aluminium is the right choice

For top hung aluminium windows, aluminium is the material that lasts. It will not rust, warp or rot, it shrugs off the South African sun, and it needs almost no maintenance beyond an occasional wipe-down.

Our frames are powder-coated in any colour, from crisp white and charcoal to bronze and natural anodised finishes, so the windows match the architecture instead of fighting it. Slim sightlines let in more glass and more daylight.

Every unit is glazed with 6.38mm laminated safety glass as standard, which improves security, cuts outside noise and holds together if it is ever broken. Double glazing and performance glass are available where thermal comfort matters.
