Internal wall insulation is where board and a coat of plaster is applied to the inside of a building. It is used to insulate solid wall properties and it creates a thermal barrier between the inside of your home and the temperature of the outside of your property. It is normally a cheaper alternative to external wall insulation and is ideal for properties where outside insulation is not suitable sandstone buildings. The installation can also be done room by room.

Our fully funded solid wall insulation, using certified systems, can improve the warmth of your property by dramatically reducing heat loss and energy bills.

Of the millions of homes in the UK, it’s estimated that around 36% have non-cavity solid walls, many of which contribute to low energy efficiency, especially during colder months.
