What Is Internal Wall Insulation?

Internal wall insulation stands as a pivotal strategy aimed at bolstering the energy efficiency of buildings by addressing heat loss through walls.

This approach involves meticulously applying insulation materials, typically rigid boards or mineral wool fibers, onto the inner surfaces of external walls. Notably, internal wall insulation offers distinct advantages, especially for properties lacking cavity walls or facing obstacles with external insulation implementation.

By establishing a thermal barrier within the structure, internal wall insulation elevates thermal comfort and facilitates significant energy conservation in the long run. This renders it a financially prudent solution for homeowners and property managers striving for sustainable and energy-efficient outcomes.

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 and involves insulating the interior walls.

  • Materials include rigid boards or mineral wool fibers.


  • May require the removal of existing wall coverings.


  • Affects room size and aesthetics but is less expensive than external insulation.

Cavity Wall insulation is for properties with cavity walls and involves filling the gap between the outer and inner wall layers.

  • The process begins with the initial drilling of holes in the walls to facilitate the injection of cavity wall insulation materials, such as mineral wool or foam.
  • These materials naturally expand to fill up the entire cavity space, ensuring comprehensive insulation coverage.
  • Once the insulation is injected, access holes are meticulously covered with plaster or similar material to maintain the property’s aesthetic integrity.
  • Cavity wall insulation significantly contributes to improved heating efficiency and reduced energy bills over time.
  • Notably, the installation process for cavity wall insulation is typically quicker and causes minimal disruption to homeowners and tenants, making it a convenient choice for energy-efficient home upgrades.

Solid wall insulating, applies to older properties without cavities, installed on the exterior.

  • Ideal for homes built before 1920.


  • Does not affect interior space.


  • More expensive but highly effective.
