External Wall Insulation

External Wall Insulation

External wall insulation, or EWI, consists of insulating the exterior walls of a house or building. The walls are insulated by applying a layer of insulated material to the walls, providing an additional protective layer between your home and the outside world.

The material we use during wall insulation varies, but usually consists of mineral wool, polystyrene, and polyurethane foam. The material is attached to the wall using an adhesive or mechanical fixing, and a layer of render can be applied on top for extra protection and to achieve a clean, polished finish.


Benefits of wall insulation

Choosing to insulate your cavity walls can offer homeowners a multitude of benefits, including but not limited to the following:

  • Enhanced energy efficiency: Exterior wall insulation can help to reduce heat loss through the walls, which can improve the energy efficiency of a building. This can result in reduced energy bills and a more comfortable living or working environment.
  • Reduced carbon footprint: By reducing the energy consumption required to heat and cool your home, wall insulation can help to reduce your home’s carbon footprint.
  • Comfortable living environment: Insulating external walls can help to regulate indoor temperatures, helping to keep your home toasty in the winter and cool in the summer months.
  • Noise reduction: Well-insulated external walls can help to reduce noise pollution, providing an extra barrier between your home and the outside world.

Overall, EWI provides a range of benefits for homeowners including improved energy efficiency, and a possible reduction in energy costs! In today’s economic climate, helping to make your home more energy efficient and reduce the need for turning on the heating, is becoming increasingly important.
