Government figures state that for the majority of houses 35% of heat is lost through the walls. It is estimated that 66% of this can be saved by insulating the walls. This is an overall saving of 25%. The cost of insulating walls is recouped in less than three years from savings on heating bills.

The walls are warmer after insulation which in most cases results in the elimination of condensation completely.
