External Wall Insulation Benefits:

  • Aesthetic appeal – External wall insulation shouldn’t just help keep your home warm during the winter and cool during the summer; it also needs to be aesthetically appealing. That’s why we choose external wall insulation that best suits your existing wall’s texture and is based on your colour preferences. That way, you can be sure that the property’s solid walls will continue to look great for years.
  • Eco-friendly – At ProGuard Exteriors Ltd, all products and procedures we use to install external wall insulation are environmentally friendly. The result is that not only are we minimising your carbon footprint by not having to consume more electricity but also that the insulation isn’t harming the environment in any way.
  • Reduces noise pollution – Insulating your external walls can help to reduce noise pollution from outside sources, such as traffic or loud neighbours. However, for this to happen, the insulation must be installed correctly, and the correct type of insulation must be used.
  • Increases property value – Insulating your external walls can improve the overall energy efficiency of your home, which can increase its value. Furthermore, high-quality external wall insulation allows the prospective buyer to save money and time in the long term, which is something most will value and happily pay more for.
  • Save money on heating bills – Our exterior wall insulation prevents freezing walls and cold rooms which means you can spend less money on heating your property.

We aim to increase your property’s comfort – External wall insulation can significantly contribute to maintaining a comfortable and consistent temperature in your house. However, the important part is choosing the right, high-quality insulation. We’re here to assist you with this, considering your budgetary constraints, the property’s age, and any existing insulation.

External Wall Insulation FAQ's

External wall insulation is a type of insulation that is installed on the outside of a building. It involves fixing insulation boards to the external walls of a building, followed by a render or cladding system to protect the insulation and provide a finished look.

External wall insulation can help to reduce heat loss from a building, resulting in lower energy bills and improved energy efficiency. It can also help to improve the appearance of a building, reduce condensation and damp, and improve sound insulation.

External wall insulation is suitable for most types of buildings, including houses, flats, and commercial properties. It is particularly useful for buildings that are difficult to insulate internally, such as those with solid walls or where space is limited.

External wall insulation is typically installed in several stages. First, any existing render or cladding is removed, and the walls are cleaned and prepared. Insulation boards are then fixed to the walls, followed by a basecoat and a topcoat of render or a cladding system.

The cost of external wall insulation depends on a range of factors, including the size of the building, the type of insulation used, and the complexity of the installation. However, it is typically more expensive than internal wall insulation.

It is possible to install external wall insulation yourself, but it is a complex and specialist job that requires experience and expertise. It is recommended that you hire a professional installer to ensure that the insulation is installed correctly and safely.

The lifespan of external wall insulation depends on a range of factors, including the quality of the installation and the materials used. However, external wall insulation can last for up to 25 years or more with proper maintenance.

Yes, there are a range of grants and funding options available for external wall insulation, particularly for those on low incomes or living in certain areas. It is worth checking with your local council or energy supplier to see if you are eligible for any funding.
