In the quest for eco-friendly housing, manufacturers of prefabricated homes have found a way to merge material sustainability and energy efficiency – the magic ingredient: corrugated board.
They create interlocking wall modules using multiple sheets of corrugated board glued together; covered with a protective film and framed with wood. (Picture above)
What’s so special about this 290mm corrugated wall? Tests have revealed that it has an incredible thermal resistance of 7.88 m2×K/W (that’s very high) and an acoustic resistance of 44db (that’s equal to bird calls or half the noise of a food blender).
Thermal resistance is one of corrugated boards’ benefits. In fact, the University of Colorado conducted tests on two identical houses: one insulated with wood fibre and one with fibreglass. The test proved that wood fibre offers energy savings of 26.4% compared to fibreglass. Put another way, the house insulated with wood fibre was 4°C warmer after a period of 9 hours without heating.
Homeowners can now insulate their homes with a sustainable and recyclable material that is cost efficient and easy to install. Most importantly, it will dramatically lower your energy bills!
