What Is Internal Wall Insulation?

Internal wall insulation stands as a key home improvement method aimed at reducing heat loss within properties.

This involves adding layers of insulation materials, typically 60 mm to 100 mm thick, to the interior surfaces of external walls.

Unlike external wall insulation, internal wall insulation proves to be a cost-effective solution, particularly suitable for properties lacking cavity walls or where cavity wall insulation isn’t feasible.

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 solid wall properties, internal insulation emphasizes insulation of the inner walls.

  • Typically, materials like rigid insulation boards or mineral wool fibers, ranging from 60 mm to 100 mm thick, are utilized for internal insulation.
  • Installation may involve the removal of existing wall coverings to accommodate the insulation materials.
  • The effects of internal insulation may be visible in the property’s interior, potentially impacting room sizes and aesthetic appeal.
  • In comparison to external wall insulation, internal wall insulation generally entails lower installation

Cavity Wall insulation is specifically designed for properties with dual-layer cavity walls, with the goal of enhancing warmth and energy efficiency.

  • Drilling holes into the outer wall to create access points.


  • Injecting insulation materials such as mineral wool or foam into the cavities.


  • Concealing the openings with plaster to preserve the aesthetic appeal of the wall.

Solid wall insulating provides a focused solution tailored for older buildings or properties that lack cavity wall construction.

  • Tailored for older buildings or properties without cavity walls.
  • Utilizes specialized methods such as external cladding or insulation boards.
  • Enhances energy efficiency and regulates thermal conditions.
  • Preserves the unique character of historic structures.
  • Maintains interior aesthetics while ensuring functionality.
  • Generally involves higher initial costs.

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 and energy bills.
  • Potential increase in property value.
  • Financial support through reduced energy needs.

Disadvantages of internal wall insulation

  • Room space reduction.
  • Installation disruptions.
  • Potential costs for ineligible applicants.
  • Maintenance issues 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).


Eligibility for free insulation grants extends beyond benefit recipients to encompass low-income households, facilitating improved energy efficiency and reduced heating expenses through schemes like ECO4.

Certified installers can conduct borescope inspections to assess the presence of cavity wall insulation, particularly relevant for homes built within the last two decades.

In addition to insulation, adopting energy-saving practices such as adjusting thermostat settings, using energy-efficient appliances, and minimizing water usage can contribute to reduced energy bills.

The Energy Saving Trust offers guidance and support across Scotland, promoting energy efficiency measures to reduce consumption, lower bills, and mitigate carbon emissions.

Wall insulation proves crucial in preventing significant heat loss, underlining its importance in enhancing energy efficiency and reducing environmental impact.

In Isle of Skye, our team specializes in internal wall insulation, bringing extensive experience and industry-leading certifications, including the prestigious PAS 2030 accreditation, to every project. This ensures that our services meet the highest standards, guaranteeing reliability and excellence.

Securing a complimentary insulation grant in Scotland, including in Isle of Skye, is made easy through various tailored schemes accessible to homeowners. Among these, the Energy Company Obligation 4 (ECO4) scheme is notable for its accessibility and effectiveness.

Endorsed by the government, the ECO4 scheme is a comprehensive UK program aimed at modernizing heating systems, reducing carbon emissions, and addressing fuel poverty. With a specific focus on enhancing the energy efficiency of the least efficient homes in Isle of Skye and across Scotland, its objective is to upgrade heating systems and overall energy performance.

Running until March 2026, the ECO4 scheme prioritizes energy efficiency enhancements. Through collaboration with energy suppliers and local authorities, eligible households in Isle of Skye and beyond are identified and provided with vital support and resources to improve their properties.
