IN CENTRAL VICTORIA’S CLIMATE, where winters are cold, summers are hot, and energy efficiency targets are rising — an insulated slab can elevate concrete from a foundation that leaks energy from your home to a foundational element in the performance of your comfortable and energy efficient home.  Poorly detailed and executed slab insulation, or lack there-of can account for significant heat loss in winter, making it harder (and more expensive) to keep homes stable in temperature. Insulating under your slab in combination with implementing some simple but clever solar passive design principles can enable your Home to reach 8-10 Stars and allow for the incredible thermal mass qualities of concrete to become the real Hero, regulating and stabilising the internal temperature of your home, and significantly minimising the need for active heating and cooling.
