While looking for cheap, green alternatives to polystyrene and polythene-based insulation, building scientists from Salford University found that giant bars of soap made out of animal waste or vegetable fat could be just as efficient at keeping heat locked inside the house, the Mirror reported.
Experts in question, Yusuf Arayici and Lee Read asserted that current materials derived from crude oil are costly to produce.
In their quest to find a perfect soap solution, the duo experimented with different materials and found that introducing straw and bubbles to the solution reduced the bulk of the finished product.
The pair has now patented their idea and hope that it will now be taken up by the building industry.
