Using external wall insulation is one of the best ways to protect a building and its inhabitants from the environment. Exterior wall insulation protects the building and its occupants from the cold and heat as well as noise and fire. Rock Wool External Slabs are made from stone and the insulation is both water repellent and vapour permeable helping to protect the building from moisture damage. They are also dimensionally stable so it will hold its shape and position over time providing durability, maintaining performance throughout the life of the building. They are non-combustible, therefore any exterior wall insulated with Rock Wool insulation will help to prevent the spread of fire, protecting the building, the occupants and its contents.
