Spray applied insulation
When Britain began its post war building boom, coal was king and energy was relatively cheap, so little thought was given to heat loss and few buildings were constructed with any meaningful level of insulation.
Seventy years on and the world is very different. With sky-high heating costs and a greater focus on the need to reduce energy consumption, builders, landlords and homeowners all take the insulation of their properties much more seriously.
But before we look at insulation it’s important to understand what’s involved. Insulation in a building is introduced to provide resistance to heat flow. The more heat flow resistance the insulation provides, the lower the likely heating [and cooling] costs. Good levels of insulation not only reduce heating and cooling costs, but also improve comfort.
