It’s time to rethink how we insulate our homes against draughts. Expanded polystyrene insulation is one of the most effective materials for sustainably insulating draughty houses. Unlike many of our Northern Hemisphere counterparts, in Australia we tend to build houses with plenty of draughts.
In colder climates, it is essential to control draughts in housing because the heating costs would be prohibitive. But here in the Southern Hemisphere we’re still learning about the merits of insulating our draughty homes sustainably to cost-effectively reduce the amount of cool air that can enter.
