What Is Internal Wall Insulation?

Internal wall insulation presents a cost-effective approach targeted at curbing heat loss within properties.

This method involves the application of insulation materials, such as rigid boards or mineral wool, onto the interior surfaces of external walls.

Notably, this technique proves highly advantageous for properties lacking cavity walls or situations where external insulation proves impractical, offering a viable solution to bolster energy efficiency and comfort levels within the premises.

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 designed for properties that have solid walls, focusing on insulating the interior walls of the building.

    • Typically, the insulation materials used range from 60 mm to 100 mm in thickness and often come in the form of rigid insulation boards or mineral wool fibers.

    • Installing internal insulation may involve removing existing wall coverings to make space for the insulation materials.

    • The outcome of internal insulation is visible within the interior of the property, which could impact the size of rooms and the overall aesthetic.

    • Compared to external wall insulation, internal wall insulation usually incurs lower installation costs.

Cavity Wall insulation is a specialized solution designed specifically for properties equipped with cavity walls, characterized by their dual-layer structure consisting of an outer and inner wall separated by a cavity. The main aim of cavity wall insulation is to enhance the warmth within homes while also conserving energy.

  • Drilling holes into the outer layer of cavity walls to access the gap.
  • Injecting insulation materials such as mineral wool or foam into these holes to fill the cavities effectively.
  • Concealing the drilled holes with plaster or a similar material to restore the aesthetic appearance of the walls.

Solid wall insulating is specifically designed to cater to older buildings or properties lacking a cavity wall structure. This method is carefully engineered to regulate indoor temperatures, enhance comfort, and conserve energy, making it an ideal choice for historic structures where preserving architectural integrity is paramount.

  • Homes constructed before 1920 often feature solid walls, which necessitate specialized insulation solutions.
  • Solid wall insulation offers versatile application methods, including external cladding, rendering (plastering), or insulation boards, allowing for seamless integration with the existing structure.
  • This approach effectively improves energy efficiency and thermal regulation within solid wall properties, ensuring a comfortable indoor environment.
  • The end result maintains the integrity of interior living spaces and aesthetic appeal without compromising on functionality. However, it’s worth noting that solid wall insulation typically involves higher upfront costs compared to internal insulation methods.

How Does Internal Wall Insulation Work?

What Are The
Advantages and Disadvantages

Of Internal Wall Insulation?

Advantages of internal wall insulation

  • Ideal for solid wall properties
  • Enhanced energy efficiency and comfort
  • Reduced carbon footprint
  • Potential increase in property value
  • Financial support through reduced energy expenses

Disadvantages of internal wall insulation

  • Potential reduction in room space
  • Disruption during installation
  • Costs for ineligible applicants
  • Maintenance concerns if not installed correctly
  • Risk of 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).


Even if not receiving benefits, households with low income may still qualify for free insulation grants under schemes like ECO 4, contributing to improved energy efficiency and reduced heating costs.

Consult certified installers to perform a borescope inspection, especially if the property was built within the last 20 years, to confirm the presence of cavity wall insulation.

Aside from internal wall insulation, there are numerous effective methods to decrease energy expenses, including:

  • Turning off lights when they’re not needed can significantly reduce electricity consumption and promote energy conservation within your home.

  • Making minor adjustments to your thermostat, like lowering it by a degree or two, can help conserve energy without sacrificing comfort levels, resulting in potential savings on your energy bills.

  • Opting for appliances with A-grade energy ratings can lead to lower energy consumption, ultimately translating into reduced utility costs over time.

  • Being mindful of the duration of your showers can contribute to conserving hot water and decreasing energy usage associated with water heating, thereby facilitating savings on your utility bills.


The Energy Saving Trust offers guidance and support to individuals and organizations in Dunfermline, aiding in energy consumption reduction, cost savings, and carbon emission reduction efforts.
