External insulation is a solution to houses built with solid concrete walls.
Solid concrete built properties were built with large sections of concrete and have no cavity. These walls are very cold and lose a lot of heat from your home. It is not always practical to fit insulated plasterboards and skim the interior of the house so this system offers an alternative method. Once the insulated boards are fixed they are then coated in a special flexible render that has polymers to allow the walls and insulation to breath but to also protect.
