Loft Insulation works by forming a thermal barrier to stop rising hot air escaping through your roof.  The air pockets in insulation trap hot air and prevent it from being lost into the atmosphere.

It is recommended 300mm (12 inches) of insulation is installed in the loft to save heat loss.  The government has simply realised this one change to our properties has the potential to help the country meet our carbon reduction targets.
