What Is Internal Wall Insulation?

Internal wall insulation entails adding insulation materials, like rigid boards or mineral wool fibers, to external wall interiors to minimize heat loss.

This cost-effective method suits properties without cavity walls or where external insulation isn’t feasible.

Contrasting with cavity wall and solid wall insulation, internal wall insulation presents unique considerations

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 tailored for properties with solid walls, prioritizing the insulation of interior walls within the structure.

  • Usually, the insulation materials utilized have a thickness ranging from 60 mm to 100 mm, commonly available as rigid insulation boards or mineral wool fibers.
  • The process of installing internal insulation may necessitate the removal of existing wall coverings to accommodate the insulation materials effectively.
  • The result of internal insulation is observable within the interior spaces of the property, potentially influencing room dimensions and overall visual appeal.
  • In contrast to external wall insulation, internal wall insulation typically involves lower installation expenses.

Cavity Wall insulation stands as a tailored remedy crafted explicitly for properties endowed with cavity walls, which are recognized for their two-tiered construction comprising an exterior and interior wall divided by a gap. The primary objective of cavity wall insulation revolves around augmenting household warmth while concurrently preserving energy.

  • Creating perforations in the outer layer of cavity walls to gain access to the void.


  • Introducing insulation substances like mineral wool or foam into these apertures to occupy the cavities thoroughly.


  • Concealing the drilled openings with plaster or a comparable substance to reinstate the walls’ aesthetic appeal.

Solid wall insulating serves as a tailored solution for older buildings or properties lacking cavity wall structures, meticulously designed to manage indoor temperatures, elevate comfort levels, and conserve energy. It proves particularly advantageous for preserving the architectural integrity of historic structures.

  • Properties constructed before 1920 commonly have solid walls, requiring tailored insulation solutions.
  • Solid wall insulation provides various application methods like external cladding, rendering, or insulation boards, enabling effortless integration with the current structure.
  • This method enhances energy efficiency and regulates thermal conditions within solid wall properties, guaranteeing a cozy indoor atmosphere.
  • The outcome preserves the integrity of interior living spaces and aesthetic charm while maintaining functionality.
  • Nonetheless, it’s important to acknowledge that solid wall insulation usually incurs higher initial expenses compared to internal insulation techniques.

How Does Internal Wall Insulation Work?

What Are The
Advantages and Disadvantages

Of Internal Wall Insulation?

Advantages of internal wall insulation

  • Suitable for solid wall properties
  • Enhanced energy efficiency and comfort
  • Reduced carbon footprint
  • Potential property value increase
  • Financial relief through lower energy bills

Disadvantages of internal wall insulation

  • Potential reduction in room space
  • Disruption during installation
  • Costs for ineligible households
  • Risk of maintenance issues with improper installation
  • Potential for dampness or 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).


Eligibility extends to low-income households, even without benefit receipt, under the ECO 4 scheme.

Certified installers can conduct inspections, especially if the property was built within the last 20 years, to confirm the presence of cavity wall insulation.

In addition to internal wall insulation, there exists a plethora of effective strategies to trim down energy expenses:

  • Turning off lights when not in use can significantly slash electricity consumption and foster energy conservation within your household. By cultivating this habit, you can make a tangible impact on reducing your energy bills.

  • Implementing minor adjustments to your thermostat, such as lowering it by a degree or two, can aid in conserving energy without compromising comfort levels. This simple practice has the potential to yield substantial savings on your energy bills over time.
  • Opting for appliances with A-grade energy ratings can pave the way for diminished energy consumption, ultimately resulting in reduced utility costs in the long run. Prioritizing energy-efficient appliances is a wise investment for both your wallet and the environment.
  • Being mindful of the duration of your showers can play a pivotal role in conserving hot water and curbing energy usage associated with water heating. By adopting this mindful approach, you can effectively trim down your utility bills while contributing to environmental sustainability.
