As Britain’s temperature records tumble and extreme heatwaves threaten to become “the norm” in the next couple of decades, the government has been slammed for its failure to help people keep buildings cool in summer and warm in winter.
Experts point out that insulation has a dual benefit – reducing our energy bills and climate emissions in winter, and helping keep down internal temperatures in the summer.
“The beauty of insulation is that it slows the process of heat moving through walls,” said Mike Childs, head of science at Friends of the Earth (FoE). “So, in the winter it stops warmth escaping from well-insulated buildings, while in the summer it does the opposite – it actually slows heat moving into our homes.”
