What Is Internal Wall Insulation?

Adding insulation to the inside of external walls is a key way to make buildings more energy-efficient. This involves putting materials like rigid panels or mineral wool fibers on the inside faces of outside walls, usually between 60 and 100 mm thick.

Adding this layer of insulation helps to significantly reduce heat loss, leading to better energy conservation and notable savings in heating costs over time.

This method is particularly useful for buildings that don’t have cavity walls or can’t use cavity wall insulation. It helps to keep indoor temperatures steady, increasing comfort for those inside. It also can make heating systems last longer, making it a smart choice for improving energy efficiency and reducing long-term maintenance costs.

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 tailor-made for properties with solid walls, aiming to insulate the inner walls while taking into account the effect on room dimensions and visual appeal.

  • Insulating the internal side of external walls is essential for increasing a building’s energy efficiency.
  • Use materials like rigid panels or mineral wool fibers, typically with a thickness ranging from 60 to 100 mm.
  • The insulation layer significantly cuts down on heat loss, leading to improved energy conservation.
  • This reduction in heat loss translates to considerable savings in heating costs over an extended period.
  • Particularly suitable for buildings without cavity walls or where cavity wall insulation isn’t an option.
  • Helps maintain steady indoor temperatures, enhancing occupant comfort.
  • Contributes to the longevity of the building’s heating systems, reducing long-term maintenance costs.
  • A strategic choice for long-term energy efficiency and maintenance savings.

Cavity Wall insulation is an optimal solution for buildings equipped with these walls, as it enhances heating efficiency while causing minimal disruption.

  • Initially, small holes are carefully drilled in the walls, creating access for the insulation material.
  • Insulation materials, such as mineral wool or foam, are then injected into these holes, expanding to fill the entire cavity space, thereby boosting the wall’s heat retention capabilities.
  • Once the insulation process is complete, these access points are meticulously sealed using plaster or similar materials, ensuring the property’s aesthetic is maintained while optimizing energy efficiency.
  • The entire cavity wall insulation process is designed to be quick and straightforward, causing minimal disturbance to homeowners or occupants.

Solid Wall insulation is specifically designed for older buildings that do not have cavity walls. It is applied externally to improve energy efficiency without changing the interior layout.

  • Solid wall insulation is specifically suited for older buildings that don’t have cavity walls, typically those built before the 1920s.
  • This insulation can be applied in several ways, including external cladding, rendering, or using insulation boards, making it adaptable to various architectural designs.
  • By improving thermal control, solid wall insulation increases energy efficiency, which in turn enhances the comfort of occupants and contributes to a more agreeable indoor environment.
  • While improving functionality, this type of insulation also maintains the visual appeal and integrity of the building’s interior, ensuring a balance between practicality and aesthetic value.
  •  Despite being more expensive than internal insulation, solid wall insulation offers significant long-term benefits in energy savings and comfort, making it a valuable investment for homeowners.

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 and comfort.
  • Reduced carbon footprint and energy bills.
  • Potential increase in property value.

Disadvantages of internal wall insulation

  • Reduced room space.
  • Installation disruption.
  • Potential costs if not eligible for a grant.
  • Risks of improper installation leading to dampness or mould.

Note: Approval for any interior wall insulation grant or home improvement funding requires management by an approved installer (e.g., Envirohomes Renewables) under specific schemes (e.g., the ECO4 scheme).


Even if you’re not receiving benefits, you may still be eligible for a free insulation grant under the ECO4 scheme, especially if your household has a low income.

The scheme provides full funding for insulation, enhancing your home’s energy efficiency and potentially lowering heating costs. Therefore, non-beneficiaries might still qualify for this government grant.

Homes constructed within the last 20 years often come with cavity wall insulation and other energy-saving features.

To verify if your home has this insulation, you can engage certified installers for a borescope inspection. This involves creating a small opening in the exterior wall to check if the cavity is filled or not.

There are multiple ways to cut down on energy bills beyond wall insulation.

Effective strategies include turning off unused lights, slightly lowering your thermostat, wearing warmer clothing indoors, using energy-efficient appliances, and taking shorter showers to save on hot water.

The Energy Saving Trust in Alloa, Scotland offers advice, information, and support similar to its initiatives in other UK regions. This organization assists individuals, businesses, and organizations in Scotland with reducing energy use, lowering energy bills, and cutting down carbon emissions.

Wall insulation is crucial as up to 45% of heat loss can occur through uninsulated solid walls, and an additional 25% through an uninsulated roof. Proper wall insulation is therefore vital in maintaining energy efficiency in a home.

In Alloa, Scotland, our dedicated team excels in providing first-rate internal wall insulation services. Our expertise is backed by comprehensive experience and distinguished credentials, including the PAS 2030 certification. This combination ensures unparalleled quality and complete satisfaction for our clients.

We are also adept at guiding homeowners through the various insulation grant programs available in Scotland and across the UK. A key program is the Energy Company Obligation 4 (ECO4) scheme, which is designed to make insulation more accessible.

The ECO4 scheme, supported by the government, is geared towards upgrading heating systems, cutting down carbon emissions, and addressing fuel poverty. It primarily focuses on enhancing the energy efficiency of the least efficient houses in Alloa and surrounding areas.

Scheduled to run until March 2026, the ECO4 scheme underscores the critical importance of improving energy efficiency. We work in close collaboration with energy suppliers and local authorities to aid eligible households in Alloa in boosting their home energy efficiency. This endeavor is a step towards a greener and more sustainable future.
