What Is Cavity Wall Insulation?

In the pursuit of a more energy-efficient home, cavity wall insulation emerges as a quiet champion. Many houses built after the 1920s feature a unique space between layers of walls, known as a cavity. While initially intended to prevent moisture, this gap unwittingly allows heat to escape, cold to seep in, and energy bills to rise. Cavity wall insulation ingeniously fills this space, making your home more energy-efficient and comfortable, irrespective of the season.

Why Consider Cavity Wall Insulation?

By trapping the requisite heat, cavity wall insulation ensures your heating system works less to maintain optimal heat levels. This efficiency reflects positively on energy bills, quietly saves insulated properties from extra heating costs.

Improved Energy Efficiency

With the indoor surface of your walls warmer, the battle with internal condensation, often a precursor to mold, becomes a non-concern.

Condensation Reduction

A Responsibility to Your Home

Cavity wall insulation requires minimal upkeep but demands a keen eye. Regular checks for any issues with damp or mold ensure the insulation serves its purpose—unseen, unfelt, but deeply experienced.

Experience a home where every room feels like a consistent climate. Installing cavity insulation can reduce discomfort of cold walls and draughty rooms

Installation Process

Sumbit Application

First, we need to complete an application form, which allows us to assess your property according to grant guidelines. An agent will then contact you to discuss potential upgrades and finalise your application.

Initial Survey

A certified technician will assess your current system and heating requirements, providing a detailed overview that often reveals potential energy savings of 15-20%.

Technical Survey

After the initial survey is complete and the mock EPC passes, your application is fully vetted. We’ll then arrange a final technical survey to confirm the specifics of the work. Following this, we'll provide an installation date.

Installation

Professional installation usually takes less than 72 hours following the technical assessment, with a seamless changeover that ensures no disruption to your home heating.

Frequently Asked Questions (FAQs)

  • The cavity is filled with insulating material (e.g., foam, beads, or mineral wool), which traps heat and prevents it from escaping, reducing energy waste.

  • You can save up to £275 annually, depending on your home’s size and energy usage 💷.

  • When installed correctly, cavity wall insulation does not cause damp. It’s important to ensure there are no existing damp issues before installation.

  • Most installations take 2–3 hours for an average-sized home 🕒.

  • Cavity wall insulation is designed to last for the lifetime of the property (typically 40 years or more) 🛡️

  • Yes! Qualification can be assessed based on the wall type, heating system, and other property factors 🔍.
