An external insulation system provides an effective solution for a wide range of home improvement problems, from draughts to air leakage. It also helps to reduce energy costs and protect the environment from excessive carbon emissions.
There are several different options for exterior house insulation the walls of a building, with each one having its own advantages, drawbacks and limitations. The type of insulation that’s best suited to a particular building structure depends on the type of construction – if a property has cavity walls, for example, it will need a different type of insulating solution than if the walls are solid.
A popular choice for insulating existing homes and commercial properties is an EWI (External Wall Insulation) system, which can be installed on both solid and cavity walls. Also known as ETICS or EIFS, it is a versatile solution that can be used for both new builds and renovations.
These systems typically consist of an adhesive, an insulation board and a base coat. Expanded polystyrene (EPS) is a common form of insulation for these systems, as it is lightweight and durable. Another option is mineral wool, which is also eco-friendly and provides a high level of thermal performance.
A more recent development in the world of EWI is a cork coating, which is breathable and a natural insulator. It’s also water resistant, meaning it doesn’t have any damp-related issues like panels do and is suitable in any climate.
