Window materials in eTool database

  • Hi eTool,

    Please can you confirm what materials are covered in your database for the window material options? E.g. “Glazing | Windows | Aluminium Framed | No Thermal Break | Double Glaze | Commercial Fixed” – does this cover the glazing or the aluminium frame? Or both? If both, how do you account for the frame thickness and ratio of frame to window?

    Hi Charlotte,

    Thanks for your question. I believe the data would be based on whatever the ‘industry average’ aluminium framed commercial double-glazed fixed window is. It’s the whole window unit so it would include both the glass and frame. For more specific frame thickness & ratio specifications used, you’ll need to inspect the source AusLCI/EcoInvent dataset which you can access via this post:

    I hope that answers your question.
