Professional Cavity Wall Insulation Services

Cavity wall insulation is a crucial step towards enhancing the energy efficiency of your home. If you live in the UK, where fluctuating weather conditions demand a reliable and consistent indoor climate, this solution can dramatically improve your property’s thermal performance, lower energy bills, and reduce your carbon footprint.

What is Cavity Wall Insulation?

Cavity wall insulation involves filling the gap between the inner and outer walls of your property with an insulating material. These cavities are common in UK homes built after the 1920s, as they were designed to reduce heat loss. However, without proper insulation, these gaps can become significant sources of heat escape.

How Does Cavity Wall Insulation Work?

The insulating material traps air within its structure, reducing heat transfer through the walls. This process helps retain warmth during colder months and keeps your home cooler during the summer. By reducing the amount of energy required to heat or cool your home, cavity wall insulation contributes to both cost savings and environmental sustainability.

Benefits of Cavity Wall Insulation

Energy Efficiency

By preventing heat from escaping, cavity wall insulation reduces the energy required to maintain a comfortable indoor temperature. This can lower your energy bills significantly.

Cost Savings

Homeowners can save up to £300 annually on their heating bills after installing cavity wall insulation.

Reduced Carbon Footprint

Using less energy helps minimise greenhouse gas emissions, making cavity wall insulation an eco-friendly choice.

Enhanced Comfort

Insulation reduces cold spots and draughts, providing a more comfortable living environment.

Increased Property Value

Energy-efficient homes are more attractive to buyers, and cavity wall insulation can improve your property’s Energy Performance Certificate (EPC) rating.

Is Your Home Suitable for Cavity Wall Insulation?

Wall Construction

Homes built after the 1920s and before the 1980s are more likely to have cavity walls. You can identify cavity walls by examining the brickwork pattern — if all bricks are laid lengthwise, it’s likely a cavity wall.

Cavity Width

The cavity should be at least 50mm wide to accommodate the insulation material.

Accessibility

The walls should be accessible for drilling and injecting the insulation material. Obstacles like extensions or conservatories may require additional considerations.

Damp Issues

Homes with existing damp problems should address these issues before installing insulation, as the process may exacerbate the condition.

The Installation Process

Assessment

A professional installer will assess your property to ensure suitability for cavity wall insulation.

Preparation

Small holes are drilled into the external walls of your property.

Injection

The insulation material is injected into the cavity using specialised equipment.

Sealing

The drilled holes are filled and matched to the existing wall finish.

FAQ

If you have high energy bills, cold walls, or noticeable draughts, it may be time to consider cavity wall insulation.

Properly installed insulation should not cause dampness. However, existing damp problems should be resolved before installation.

The process typically takes between 2 to 4 hours, depending on the size of the property.
