What is Cavity Wall Insulation?

Many homes built in the UK from the 1920s onwards were constructed with cavity walls. A cavity wall consists of two layers of brick or block with a small gap between them. While this gap helps prevent rainwater from reaching the inside of your property, it can also allow valuable heat to escape if left uninsulated.

Cavity wall insulation works by filling this gap with specially designed insulating material that traps air and significantly reduces heat transfer. Once installed, your home stays warmer during winter and cooler during summer, reducing the need for excessive heating or cooling.

If your property has suitable cavity walls, insulation can greatly improve its energy efficiency while enhancing everyday comfort.

Benefits of Cavity Wall Insulation

  • Lower Energy Bills: A large proportion of heat loss in an uninsulated home occurs through external walls. By reducing this heat loss, cavity wall insulation helps your heating system work more efficiently, leading to noticeable savings on your energy bills.
  • Improved Energy Efficiency: Insulating your walls improves your property's overall thermal performance. By keeping more heat inside your home, less energy is required to maintain a comfortable temperature, helping improve your home's energy efficiency.
  • A More Comfortable Home All Year Round:
  • Cavity wall insulation helps regulate indoor temperatures throughout every season.
  • During summer, it helps reduce unwanted heat entering from outside.
  • The result is a home that feels consistently comfortable regardless of the weather.
  • Reduced Outside Noise: In addition to improving thermal performance, many insulation materials also provide excellent sound insulation. They can help reduce traffic noise, neighbourhood sounds, and other external disturbances, creating a quieter indoor environment.
  • Lower Carbon Emissions: Using less energy for heating means reducing your household's carbon emissions. Installing cavity wall insulation is a simple but effective way to make your home more environmentally friendly while contributing to a more sustainable future.
  • Increase Your Property Value: Energy-efficient homes are increasingly attractive to buyers. Improving your property's insulation can enhance its Energy Performance Certificate (EPC) rating, making it more appealing should you decide to sell in the future.

Is My Home Suitable for Cavity Wall Insulation?

Most homes built between the 1920s and the late 1990s have cavity walls and may be suitable for insulation.

Before any installation begins, our experienced surveyors carry out a detailed inspection to assess:

  • The construction and condition of your walls
  • Cavity width
  • Existing insulation (if any)
  • Signs of damp or structural issues

If your property is suitable, we’ll recommend the most appropriate insulation solution for maximum performance.

Our Installation Process

Our installation process is designed to be quick, efficient, and minimally disruptive.

  • Property Survey: We begin with a professional assessment to confirm your home's suitability and identify any issues that should be addressed before installation.
  • Preparing the Walls:Small access holes are carefully drilled into the external mortar joints at specific locations to allow the insulation material to be installed evenly throughout the cavity.
  • Installing the Insulation: Using specialist equipment, the insulation material is injected into the wall cavity until it is completely filled, ensuring consistent coverage with no significant gaps.
  • Finishing the Wall: Once installation is complete, all access holes are carefully sealed and colour-matched wherever possible, leaving your property's appearance virtually unchanged.
  • Final Quality Inspection: Before completion, our installers carry out a thorough inspection to ensure the insulation has been installed correctly and meets our quality standards.
