What Is Internal Wall Insulation?

Implementing internal wall insulation is a key strategy for boosting the energy efficiency of buildings, focusing on minimizing heat escape through walls.

This technique involves the precise placement of insulating materials, like rigid boards or mineral wool fibers, on the inner sides of a building’s exterior walls. It’s an especially advantageous approach for buildings lacking cavity walls or where applying external insulation isn’t feasible.

By forming a thermal barrier within the structure, internal wall insulation substantially enhances indoor thermal comfort and contributes to notable long-term energy savings. Consequently, it emerges as an economically viable and eco-friendly option for homeowners and property administrators dedicated to fostering sustainable, energy-efficient environments.

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 a technique specifically designed for properties with solid walls, involving the application of insulation on the internal walls.

  • This approach is highly efficient in minimizing heat loss, thereby improving the overall energy efficiency and comfort levels within homes.


  • Typically, the procedure entails affixing materials such as rigid foam boards or mineral wool onto the walls, followed by their encasement with plasterboard or comparable materials.


  • Opting for this method is particularly advantageous for properties where maintaining the external façade is of paramount importance.

Cavity Wall insulation is ideal for buildings that feature a space between two layers of walls.

  • This approach entails creating tiny holes in the exterior wall and filling the gap with insulating substances such as foam or mineral wool.


  • This technique proficiently blocks heat from seeping out through the walls, ensuring the interior of the house remains comfortably warm.


  • Due to its negligible effect on the external look of the property and its swift installation, this method is widely favored.

Solid wall insulating, is an external method predominantly applied to older structures that lack cavity walls.

  • This technique involves attaching insulation to the outer walls of the building, which is subsequently shielded with materials such as render or cladding.


  • Although this approach may change the external look of a property, it excels in enhancing its thermal performance and energy efficiency.


  • This method is especially beneficial for older buildings where internal insulation may not be feasible due to limited space.

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.
  • Improved energy efficiency.
  • Enhanced warmth and comfort.
  • Reduced carbon footprint.
  • Potential increase in property value.

Disadvantages of internal wall insulation

  • Reduction in room space.
  • Potential disruption during installation.
  • Costs, if not eligible for grants.
  • Risk of dampness or mold if not installed correctly.

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


Even without benefits, low-income households may qualify for the ECO4 scheme, enabling energy-efficient upgrades like internal wall insulation.

For homes built in the past 20 years, a borescope inspection by certified installers can confirm existing insulation.

Beyond insulation, energy bills can be reduced by switching off unused lights, lowering the thermostat, using energy-efficient appliances, and conserving hot water.

In Scotland, this trust offers advice and support for reducing energy consumption, lowering bills, and cutting carbon emissions.

Absolutely. Up to 45% of heat loss can occur through uninsulated solid walls, highlighting the importance of proper insulation.

In Pumps Islay, Scotland, our team of internal wall insulation specialists is celebrated for their profound expertise and experience in every undertaking. With high-level qualifications, including the esteemed PAS 2030 accreditation, we guarantee that each installation conforms to strict standards, providing our clients with reliability and confidence.

The process of securing a free insulation grant in Scotland and the UK is made efficient, thanks to a variety of custom-tailored schemes addressing homeowners’ specific needs. Prominently, the Energy Company Obligation 4 (ECO4) scheme emerges as a significant and reachable program.

Backed by the government, the ECO4 scheme is an extensive UK-wide effort focused on renovating heating systems to reduce carbon emissions and combat fuel poverty. It especially aims at enhancing the heating efficiency of the least energy-efficient homes in Pumps Islay and across the UK, striving to elevate the overall energy efficiency.

Scheduled to continue until March 2026, the ECO4 scheme emphasizes the advancement of energy efficiency. In partnership with energy suppliers and local authorities, the scheme works to identify and support eligible households, enabling them to implement crucial improvements to their properties.
