Why is insulation important for your home? With research showing that 40% of UK homeowners worry about the cost of heating our homes, the Energy Saving Trust examines answers the importance – and best types – of insulation for an energy efficient home.

While installing a heating system that reduces your energy bills is an attractive option, the key to reducing your reliance on heating altogether is to take a ‘fabric first’ approach. This means addressing the issues that allow heat to escape and cold air to enter your home.

Solid vs cavity wall insulation

Around one third of all the heat lost in an uninsulated home escapes through the walls. This can be addressed with the installation of solid wall or cavity wall insulation. Solid wall insulation can be applied to either the exterior of your home or the interior – each with its own pros and cons.

Cavity wall insulation is installed in homes with unfilled wall cavities by drilling into these cavities and filling with a spray foam.
