Yes — you can request to upgrade a standard bedroom window to a sliding glass door, subject to energy efficiency approval and site-specific assessment.

Here’s what you need to know:

The option to upgrade a window to a door depends on whether the change affects the home’s overall energy rating, which is assessed during the Site Assessment phase.

Our energy consultant will evaluate the impact of adding a door based on factors like glazing, orientation, shading, and climate zone.

If the change is approved by the energy assessor, the upgrade can be included in your fixed-price quote.

Upgrade details:

The door used is our Expandify thermal break sliding glass door

Features a 3-track aluminium frame, metal flyscreen, and full thermal break system

Measures 2100mm high x 2000mm wide

Engineered to suit all Expandify models

Cost for the upgrade:
There is a $1,000 fee per sliding door upgrade, which covers the structural modification, upgraded materials, and integration into the folding system.

Requests must be made during quoting or before your batch is locked.
