EnviraSlim Sliding and Stacking Door

Premium hardware and design details like the lowline flush threshold sill provide outstanding performance and aesthetics that are built to last. We've focused on the small details too, as we know they make a big difference, like the bespoke heavy-duty 32mm roller system which provides smooth and easy operation and installation; the concealed, shadowline integrated drainage and panels that can be reversed on-site allowing for handling flexibility pre or post-installation. No matter your style, building choices, size or performance preferences, the EnviraSlim Sliding & Stacking Door works for you.

More information to help you plan your project:


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.

Find our WERS ratings here.

Thermally broken aluminium has the following advantages: Aluminium is durable and a proven material for use as windows and doors in Australia, there is no fading or distorting when exposed to UV. Aluminium will also get you larger openings and suite higher bushfire rated areas.

Raise the bar with your next project using the Envira Collection of thermally broken energy efficient windows and doors.
