Custom


Different shapes, sizes and configurations can be created to fit your home.

Louvres


Louvres are a contemporary option that offer maximum ventilation. Our louvres open fully to allow fresh air in yet seal tight to ensure protection from the elements.

  • Open wide to maximise ventilation in comparison to other window types
  • Aluminium frame with louvre blades available in glass (single glazed), aluminium or timber
  • Cyclone tested for wind and water to ensure maximum performance
  • Breezes can be captured no matter which direction they're coming from
  • Can be used alongside walkways as they don't project far beyond the wall.

Roof


Roof windows allow natural light into your home and can increase ventilation. A range of sizes are available, with options for partial opening with some rain protection.

  • A thermal break reduces condensation and retains interior heat
  • Dual colour allows you to match the roof and interior colours
  • Choose from manual or electric opening models
  • Fixed option also available.
