What Is Internal Wall Insulation?

Internal wall insulation plays a crucial role in enhancing the energy efficiency of buildings, primarily by reducing heat loss through walls.

The process involves the careful application of insulation materials, such as rigid boards or mineral wool fibers, to the interior surfaces of the building’s external walls. This method is particularly beneficial for properties that do not have cavity walls or where external insulation is not a viable option.

The creation of this thermal barrier inside the building significantly improves thermal comfort and leads to considerable energy savings over time. As a result, internal wall insulation is a cost-effective and environmentally friendly choice for homeowners and property managers who are committed to achieving sustainable and energy-efficient living spaces.

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 used for properties with solid walls, this method involves applying insulation to the interior walls.

  • It’s effective in reducing heat loss from inside, leading to enhanced energy efficiency and comfort in homes.


  • The process often includes installing materials like rigid foam boards or mineral wool directly onto the walls, then covering them with plasterboard or similar materials.


  • This method is ideal for properties where preserving the external appearance is crucial.

Cavity Wall insulation is suitable for properties with a gap between two wall layers.

  • The process involves drilling small holes in the outer wall and injecting insulation material, like foam or mineral wool, into the cavity.


  • This method is effective in preventing heat from escaping through the walls, thereby maintaining a comfortable temperature inside the house.


  • It’s a popular choice due to its minimal impact on the property’s appearance and relatively quick installation process.

Solid wall insulating, is an external approach, typically used for older buildings without cavity walls.

  • The insulation is applied to the external walls, which is then covered with protective materials like render or cladding.


  • While this method can alter the external appearance of a property, it is highly effective in improving thermal performance and energy efficiency.


  • It’s particularly useful in older properties where internal insulation might be impractical due to space constraints.

How Does Internal Wall Insulation Work?

What Are The
Advantages and Disadvantages

Of Internal Wall Insulation?

Advantages of internal wall insulation

  • Ideal for properties in the Borders Isle of Arran with solid walls.
  • Increases energy efficiency and comfort.
  • Reduces carbon emissions.
  • Enhances property value.
  • Financial support is available for those who qualify.

Disadvantages of internal wall insulation

  • Possible reduction in room size.
  • Disruption during installation.
  • Costs for those not eligible for grants.
  • Risk of improper installation leading to dampness or mold.

Note: It’s essential to use an approved installer, like Envirohomes Renewables, especially under schemes like ECO4.


Low-income individuals may qualify for the ECO4 scheme even without benefits.

For homes built in the last 20 years, a borescope inspection can confirm the presence of cavity wall insulation.

Effective methods include using energy-efficient appliances and implementing cost-saving practices in daily life.

The Energy Saving Trust offers advice and support in Scotland for reducing energy consumption and emissions.

Wall insulation is crucial as a significant amount of heat can be lost through uninsulated walls, making it essential for energy conservation.

Our team of internal wall insulation experts in the Borders Isle of Arran is renowned for their extensive experience and proficiency in each project. Equipped with top-tier qualifications, including the prestigious PAS 2030 accreditation, we ensure that every installation adheres to stringent standards, offering our clients dependability and assurance.

Acquiring a free insulation grant in Scotland and the UK has been streamlined, courtesy of various bespoke schemes that cater to the specific requirements of homeowners. Among these, the Energy Company Obligation 4 (ECO4) scheme stands out as a notable and accessible initiative.

Supported by the government, the ECO4 scheme is a comprehensive UK-wide endeavor aimed at updating heating systems to mitigate carbon emissions and alleviate fuel poverty. Focused particularly on improving the heating systems of the least energy-efficient homes throughout the Borders Isle of Arran and beyond, its primary goal is to boost overall energy efficiency.

Set to run until March 2026, the ECO4 scheme underscores the importance of progressing in energy efficiency. Collaborating with energy suppliers and local authorities, it identifies and assists eligible households in obtaining the necessary support and resources to make vital enhancements to their homes.
