Envira Collection

Energy-efficient windows and doors from Australia’s original craftspeople.

With exceptional energy performance matched with striking looks, you can create a home of comfort and quality with the Envira Collection of thermally broken aluminium windows and doors.

what does thermally broken mean?

Thermally broken windows and doors use an aluminium frame with a polyamide strip separating the internal and external sections of the frame. This nylon-like strip reduces the amount of heat or cold transferred into a home, making it more comfortable and energy efficient.


Designed to be built into Australia's most popular construction methods.


Offset reveal is standard, with an inline adaptor available.


Double glazing as standard provides superior energy performance.


A range of trims to make finishing easier.

No, Envira Collection was designed in Australia by our team. The key principle we used is that we wanted to keep it simple and we did not want to add anymore complexity into using windows and doors, so builders don’t need to do anything different. Build you homes and build in your windows exactly the same as our standard aluminium suites.

If you can build it, Envira will suite it! Designed to suite all popular methods of standard Australian building construction methods. If you’re not sure, just talk to your Stegbar expert.  

Envira Collection is an offset reveal product as standard, but comes with an inline reveal adaptor. Making it perfect for renovation work as well as new builds. You also have the choice of a number of reveal depths/sizes and materials, including  KDHW (kiln dried hardwood) or primed FJ pine.

Yes, you can choose to have your windows without flashing or with NCC compliant sill flashing; sill and jamb flashing; or sill, jamb and head flashing.

We are offering a range of trims and finishing options, including the innovative Stegbar compensating apron/sill flap; a bulb seal to finish off the windows in brick construction (and to reduce caulking); as well as weatherboard and flat trims to reduce unsightly gaps. Ask your Stegbar expert for more information.

Yes, absolutely, it may involve changing some of the other building materials in your project, but Envira windows and doors and our range of Comfort energy efficient double glazing will support more demanding energy efficiency needs.
