External Wall Insulation (EWI)

With over 30% of a building’s heat lost through its external walls, investing in effective insulation is one of the best ways to improve energy performance and reduce heating costs.

External Wall Insulation (EWI) – also known as Insulated Render Systems – offer a flexible, cost-effective solution.

EWI is one layer of insulation that ranges in different thickness. By adding this to exterior walls and finishing with a protective render, these systems minimise heat loss, repel water, withstand harsh weather conditions, enhance structural stability and modernise a building’s appearance.

With our extensive experience installing EWI systems, we fully understand the advantages of this solution for various projects.

What are the key benefits of External Wall Insulation?

Thermal efficiency

EWI systems reduce heat loss through the building’s external walls, leading to lower energy use and substantial savings on heating and cooling bills.

Weather resistance

The durable render finish shields against harsh environmental conditions, protecting the building’s structure from moisture, wind and temperature changes.

Aesthetic enhancement

EWI systems offer many variations in design, with a wide range of textures, finishes and colours to suit various architectural styles.

This allows for modernising or preserving a building’s appearance, tailored to individual needs.

Environmental impact

By reducing heat loss, insulated render systems significantly lower carbon footprints, helping buildings meet sustainability targets and be much kinder to the environment.
