CAVITY WALL INSULATION

An Effective Way to Cut Heat Loss and Energy Bills

If your home was built after the 1920s, there's a good chance it has cavity walls—external walls made of two layers with a gap in between. Without proper insulation, that gap allows valuable heat to escape, making your home less energy efficient and more expensive to heat.

At Eco Home Installations, we provide expert cavity wall insulation to help homeowners stay warmer, lower their energy bills, and reduce their carbon footprint

Cavity wall insulation involves filling the gap (or ‘cavity’) between the inner and outer layers of your home’s external walls with insulating material. This helps to trap heat inside, reducing the amount of energy needed to keep your home comfortable

• Lower Energy Bills
  Proper insulation can reduce heat loss by up to 35%, meaning you’ll spend less on heating your home.
• Increased Comfort
  Enjoy a warmer, more comfortable indoor environment all year round.
• Reduced Carbon Footprint
  Less energy use means fewer CO₂ emissions, helping to tackle climate change.
• Quick Installation
  Most cavity wall insulation can be completed in just a few hours with minimal disruption.
• Long-Lasting Results
  Once installed, insulation typically lasts for the lifetime of the building.

We offer a selection of high-performance insulation materials, each chosen for their durability, effectiveness, and environmental impact:

• Made from rock or glass fibres
• Fire-resistant and water-repellent
• Excellent thermal and acoustic properties

• Small, lightweight beads injected into the cavity
• Provide excellent coverage with minimal settling over time
• Ideal for narrow or irregular cavities

• Expands to fill even the tightest gaps
• High thermal performance
• Often used in hard-to-treat properties

Our experts will assess your home to determine the best insulation type based on your wall structure, location, and individual needs

In some cases, existing cavity wall insulation may need to be removed—particularly if it was poorly installed, has become damp, or is causing structural issues such as cold spots or penetrating damp. At Eco Home Installations, we offer professional cavity wall insulation removal using specialist extraction equipment. We’ll carry out a detailed inspection to assess the condition of your current insulation, safely remove any compromised materials, and advise on the best way to re-insulate your home. Whether you're experiencing problems or simply want peace of mind, our team is here to help.
