Is External Wall Insulation Worth It?

An uninsulated property can lose a significant amount of heat through its external walls, leading to colder rooms, higher energy consumption, and increased heating costs. In many older properties, warm air meets cold wall surfaces, which can contribute to condensation, damp, and mould growth.

External wall insulation helps tackle these issues by creating a thermal barrier around the building, keeping heat inside and improving overall comfort while reducing energy waste.

External wall insulation systems typically use materials such as EPS (Expanded Polystyrene), Mineral Wool, or Kingspan insulation boards. The boards are mechanically fixed to the external walls before being covered with a reinforced basecoat, fiberglass mesh, primer, and a decorative textured finish available in a wide range of colours.

Improving your property's energy efficiency can help increase its value. A well-insulated home with a higher EPC rating is often more attractive to buyers and tenants, making external wall insulation a worthwhile long-term investment.
