Today we carried out an experiment and proved that homes with both insulation in the roof and wall cavity were slower to lose heat than a] a home with no insulation, b] a home with insulation in the wall cavity only or c] a home with insulation in the roof only. To test this we used plastic tubs, smaller plastic cups, cotton wool, cardboard and of course thermometers. Our results were as follows:
After 8 minutes the house with no insulation dropped 8 degrees, the house with wall cavity insulation dropped 3 degrees, the house with insulation in the roof dropped 3 degrees, BUT the house with roof AND wall cavity insulation only dropped 2 degrees.
