Please Note:The technical advice provided by the Alternative Technology Association as part of the 'Ask an Expert' forum/website, in relation to home and building sustainability improvements, is general in nature only. The impacts of specific energy or water saving or sustainability products will depend on the specific application, and particularly for larger investments, we would always suggest users seek a specific assessment from an appropriately qualified building designer or service / product supplier.
