What is wall insulation?

Wall insulation involves adding a layer of insulation material to the outside of a building's walls (like wrapping a building in a warm blanket). The insulation boards are then covered with a special mesh and several layers of render  to protect it from the weather and to improve the building's appearance.

The main goal is to retain the heat inside your home for longer during colder months and make the home cooler during warmer months, making the building more energy-efficient and comfortable to live in. This can help reduce energy bills and also decrease the building's carbon footprint by reducing the need for heating and cooling.

What are the benefits?

Wall insulation offers several benefits for homes, particularly given the UK's climate and energy efficiency standards. EWI provides a comprehensive solution to improve energy efficiency, comfort, and the longevity of homes in the UK.

Thermal efficiency

Wall insulation significantly reduces heat loss through walls, which are one of the biggest sources of energy loss in buildings. By wrapping the exterior in a layer of insulation, it creates a continuous thermal barrier. This improvement leads to more stable indoor temperatures, reduced need for heating and cooling, and lower energy bills.

Energy savings

With better thermal retention and efficiency, buildings require less energy to maintain comfortable living conditions. This reduction in energy usage not only lowers utility costs but also decreases the building's carbon footprint, contributing to environmental conservation.

Improved aesthetics

Insulation provides an opportunity to refurbish the external appearance of a building. It can be finished with a variety of materials and colours, offering aesthetic improvements that can increase property value and curb appeal.

Property value

The improved aesthetic appeal combined with enhanced energy efficiency can increase a property's marketability and value. Prospective buyers or tenants often value the upgraded appearance and energy savings, making properties with wall rendering more attractive in the property market.

Environmental impact

Beyond reducing operational energy use, Wall rendering also lowers the environmental impact during the heating and cooling phases of a building's life cycle. This contributes to sustainability goals by reducing greenhouse gas emissions.

Durability & protection

Wall insulation protects the existing external walls from weather impacts, such as rain, frost, and thermal stress from fluctuations in temperature. This protection can extend the life of the building materials, reducing maintenance costs and preserving the structure.
