What Is Internal Wall Insulation?

Internal wall insulation constitutes a comprehensive strategy crafted to enhance a property’s energy efficiency. It involves the incorporation of insulation materials, typically measuring between 60mm to 100mm thick, onto the inner surfaces of exterior walls. The primary aim is to minimize heat loss within the structure.

This method proves particularly advantageous for properties lacking cavity walls or where external insulation isn’t feasible. By opting for internal wall insulation, homeowners establish a robust thermal barrier within their homes, effectively reducing heat transfer and bolstering overall energy conservation.

The benefits extend beyond mere comfort, as internal wall insulation also leads to significant long-term energy savings and contributes to environmental sustainability.

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 solid-wall properties, focusing on insulating interior walls to enhance energy efficiency.

    • Suited for solid wall properties in Coatbridge
    • Involves adding insulation materials to the interior walls
    • Cost-effective alternative to external insulation for homes.

Cavity Wall insulation is tailored to properties featuring cavity walls, comprising an outer and inner wall separated by a space.

  • Fills the gap between inner and outer walls with insulation materials


  • Enhances heating efficiency and reduces energy consumption


  • Typically installed in properties with cavity walls in Coatbridge

Solid wall insulating, is tailored for older or solid wall properties and applied externally to the building. This method boosts energy efficiency, enhances thermal performance, and improves the property’s appearance.

  • Properties built before 1920 commonly have solid walls, reflecting construction practices of the time.
  • Solid wall insulation utilizes techniques like external cladding, rendering, or insulation boards to boost thermal efficiency.
  • This type of insulation greatly enhances energy efficiency and thermal regulation, reducing the need for excessive heating and cooling.
  • Unlike internal insulation methods, solid wall insulation is applied externally, preserving interior spaces and minimizing disruption during installation.

Insulating solid walls typically entails a greater upfront cost in contrast to internal insulation alternatives.

How Does Internal Wall Insulation Work?

What Are The
Advantages and Disadvantages

Of Internal Wall Insulation?

Advantages of internal wall insulation

  • Ideal for homes with solid wall constructions, offering effective insulation solutions tailored to such properties’ specific needs.
  • Significantly improves energy efficiency, ensuring that homes stay warm and comfortable throughout the year.
  • Contributes to environmental sustainability by reducing carbon emissions and promoting greener living practices within the community.
  • Enhances the overall value of properties making them more desirable to potential buyers or tenants.
  • Provides financial support to homeowners by lowering energy bills through reduced energy consumption, ultimately leading to long-term cost savings and financial stability.

Disadvantages of internal wall insulation

  • Internal wall insulation may slightly reduce room space due to added insulation materials.
  • Expect temporary disruptions during installation, such as moving furniture.
  • Ineligible applicants may face unexpected costs for insulation.
  • Poorly installed insulation can lead to increased maintenance expenses.
  • Inadequate insulation may raise the risk of dampness and 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).


While the main focus of eligibility is on low-income households and those receiving benefits, individuals with a limited income may still be eligible for complete funding through the ECO4 scheme, regardless of their benefit status.

This funding offers a substantial boost to energy efficiency efforts and leads to significant reductions in heating costs for homeowners who meet the eligibility criteria.

It’s common for homes built within the past twenty years to already have insulation, including cavity wall insulation. However, if you’re unsure whether your home has insulation or not, there are ways to confirm its presence.

Certified installers can conduct a borescope inspection to verify the status of insulation. This involves making a small hole in the exterior wall to assess whether insulation is present and its condition.

Beyond wall insulation, there are various strategies to effectively reduce energy bills, including:

  • Turning off lights when they’re not needed, significantly reducing electricity consumption.
  • Making small tweaks to your thermostat settings, lowering it by just a degree or two, to save energy without sacrificing comfort.
  • Considering wearing warmer clothing like sweaters or socks indoors to reduce the need for heating, thereby decreasing energy usage.
  • Investing in energy-efficient appliances with A-grade ratings, as they consume less energy, leading to overall lower energy consumption in your household.
  • Being conscious of your shower time to conserve hot water, which in turn reduces energy usage and helps in cutting down on utility bills.

The Energy Saving Trust provides valuable support for energy efficiency initiatives in Coatbridge and across Scotland.

Absolutely, given Coatbridge’s climate conditions, proper wall insulation is crucial for reducing heat loss and improving energy efficiency in homes throughout the area.


In Coatbridge, our adept team specializing in internal wall insulation brings a wealth of expertise and holds prestigious certifications, including the esteemed PAS 2030 accreditation.

Securing a complimentary insulation grant in Scotland and the UK is a streamlined process, with various schemes tailored to suit homeowners’ needs. One prominent initiative is the Energy Company Obligation 4 (ECO4) scheme, renowned for its accessibility and impact.

Endorsed by the government, the ECO4 scheme is a comprehensive UK program designed to modernize heating systems, combat carbon emissions, and address fuel poverty. With a specific focus on improving the least energy-efficient homes across Scotland and the wider UK, its aim is to elevate heating systems and overall energy efficiency.

Scheduled to continue until March 2026, the ECO4 scheme places significant emphasis on enhancing energy efficiency. Through collaborative efforts with energy suppliers and local authorities, eligible households are identified and offered essential support and resources to upgrade their residences.
