What Is Internal Wall Insulation?

Internal wall insulation is a comprehensive approach aimed at bolstering the energy efficiency of a property. This technique involves the incorporation of insulation materials, typically ranging from 60mm to 100mm in thickness, onto the interior surfaces of external walls. By implementing this process, the objective is to significantly reduce heat loss within the premises. 

This method is especially advantageous for properties that lack cavity walls or where the installation of external insulation proves to be unfeasible or impractical. With internal wall insulation, homeowners can create a robust thermal barrier within their living spaces, effectively minimizing heat transfer and enhancing overall energy conservation efforts. This approach not only fosters a more comfortable indoor environment but also contributes to substantial long-term energy savings and environmental sustainability.

What is the difference between
internal wall, cavity wall and solid wall insulation?

While all these insulating techniques serve as energy efficiency improvements, they do vary slightly in their function and application.

Internal insulation is specifically tailored for properties equipped with solid walls, emphasizing the insulation of the interior walls of the structure.

    • Internal insulation is specifically designed for properties with solid walls, focusing on insulating the interior walls of the building.
    • Insulating materials, typically ranging from 60 mm to 100 mm in thickness, commonly include rigid insulation boards or mineral wool fibers.
    • Installation may necessitate the removal of existing wall coverings to accommodate the insulation materials.
    • The final result of internal wall insulation is visible within the interior of the property, potentially influencing room sizes and overall aesthetics.
    • Despite potential aesthetic considerations, internal wall insulation is generally a more cost-effective option compared to external wall insulation.

Cavity Wall insulation is designed for properties with two layers of walls separated by a cavity. Insulating this space helps retain heat indoors and conserve energy.

  • Insulation Procedure: The insulation process commonly involves drilling holes into the walls to facilitate the injection of cavity wall insulation materials such as mineral wool or foam.

  • Material Injection: Once the holes are drilled, cavity wall insulation materials are injected into the walls. These materials expand upon injection, effectively filling the cavity space and providing optimal insulation.

  • Hole Concealment: After the insulation injection, the access holes are concealed using plaster or similar materials. This ensures a seamless integration with the property’s exterior, preserving its aesthetic appeal.

  • Benefits of Cavity Wall Insulation: Cavity wall insulation offers numerous advantages, including improved heating efficiency, decreased energy expenditures, and heightened overall energy performance within residential spaces.

  • Swift Installation: One notable benefit of cavity wall insulation is its relatively quick installation process, resulting in minimal disruption for both homeowners and tenants.

Solid wall insulating, is tailored for older or solid wall properties, applied externally to enhance thermal efficiency. It targets buildings lacking cavity walls, effectively reducing heat loss and improving energy performance.

  • Older homes, typically those built before 1920, often have solid walls.

  • Application Methods: Various techniques, including external cladding, rendering, or insulation boards, are used for solid wall insulation.

  • Enhanced Energy Efficiency: Solid wall insulation improves energy efficiency and thermal regulation, reducing the need for heating and cooling.

  • Minimal Interior Disruption: Unlike internal insulation, solid wall insulation is installed externally, minimizing disruption to interior spaces.

Solid wall insulation may incur higher upfront costs compared to internal options.


How Does Internal Wall Insulation Work?

What Are The
Advantages and Disadvantages

Of Internal Wall Insulation?

Advantages of internal wall insulation

  • Internal wall insulation is ideal for solid wall properties.
  • It significantly improves energy efficiency within the home.
  • By effectively retaining heat, it enhances overall warmth and comfort levels.
  • Internal wall insulation actively contributes to reducing the carbon footprint of a property.
  • Installation of internal wall insulation can lead to an increase in the market value of the home.
  • It provides financial relief by reducing energy consumption and associated expenses.

Disadvantages of internal wall insulation

  • Reduction in available room space
  • Disruption experienced throughout the installation process
  • Possible costs incurred if eligibility for a free insulation grant is not met
  • Increased maintenance expenses if insulation installation is improperly executed by trained professionals
  • Risk of dampness and mold growth

Note: For any interior wall insulation grant or home improvement funding to be approved, it must be managed by an approved installer (such as Envirohomes Renewables) by the specific scheme (such as the ECO4 scheme).


If your household belongs to the category of low-income earners or individuals receiving benefits, you may be eligible for substantial funding to finance insulation expenses through the ECO4 scheme. This financial aid plays a crucial role in improving the energy efficiency of your residence, leading to significant decreases in heating costs. It’s worth noting that eligibility for a government insulation grant isn’t limited to benefit recipients; households without such benefits may still fulfill the requirements for this assistance.

If your home was constructed within the last two decades, there’s a high likelihood that the walls have already been insulated, along with other energy-saving measures. To confirm this, you have the option to enlist certified professionals to perform a borescope inspection. This procedure involves creating a small aperture in the exterior wall, enabling experts to determine whether the walls are insulated or devoid of insulation material.

There exist various tactics for reducing energy costs:

  • Opt for energy-saving practices like turning off lights when not in use to minimize electricity consumption.
  • Consider adjusting your thermostat by a degree or two lower to conserve energy without compromising comfort.
  • Embrace warmer clothing options such as sweaters or socks indoors to reduce the need for heating.
  • Upgrade to energy-efficient appliances with A-grade ratings to lower overall energy consumption in your home.
  • Consciously limit your shower time to conserve hot water, thereby reducing energy usage and utility costs.
