    What are the environmental and sustainability aspects of GFRC panels. I can see many advantages of the system but id there any information regarding the carbon footprint of GFRC panels?

    This is a very topical issue and as such we hope that more comprehensive information will be available in due course. At present there is a limited amount of prepared information, principally the ‘Environmental Report’. This is a study of particular product area, cable ducting and drainage channels, but we believe it is illustrative of the general position and the findings can also be applicable to GFRC panels.

    The main advantages of GFRC elements in these respects can be summarized as having a low weight compared to alternative products such as precast concrete or cast stone.

    This leads to benefits of

    1, Economy of delivery (more items per truckload). This has a direct bearing on carbon footprint

    2, At installation, for smaller items manual lifting may be possible, or light hoisting equipment only needed.

    3, Building structure and foundations can be lighter for GFRC panels than for heavier concrete panels.

    GFRC is also generally composed of inorganic materials (a small content of polymer is sometimes used) and the glass fiber itself is manufactured principally from silica and zircon sands. Waste GFRC is harmless and can be crushed – there is even a fledgling interest in recycling by using milled waste glass fiber as an aggregate in new  GFRC.

    I’ve heard that GFRC scores well in the internationally recognised environmental rating systems such as BREEAM and LEED. Can anyone comment and add some substance to these claims?

    Graham, compared to precast concrete, GFRC is certainly a more environmentally friendly material, as the cross section (and weight) of a GFRC panel is substantially less than a concrete one. If you want a more in depth answer, see http://www.grca.org.uk/congress/downloads/3%20Is%20GRC%20a%20Green%20Building%20Material.pdf
