What Is Internal Wall Insulation?

Internal wall insulation is a vital method employed to significantly improve the energy efficiency of buildings by mitigating heat loss through walls.

This process entails the careful application of insulation materials, which commonly include rigid boards or mineral wool fibers, onto the interior surfaces of external walls. Unlike other insulation methods, internal wall insulation is particularly advantageous for properties without cavity walls or where external insulation poses practical challenges.

By creating a thermal barrier within the property, internal wall insulation effectively enhances thermal comfort and contributes to substantial energy savings over time, making it a cost-effective solution for homeowners and property managers alike who are seeking sustainable energy-efficient solutions.

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 specifically designed to cater to properties with solid walls, focusing primarily on enhancing the insulation of the interior walls within the structure.

  • Insulation materials typically range from 60 mm to 100 mm in thickness, commonly comprising rigid insulation boards or mineral wool fibers.
  • Installation may require the removal of existing wall coverings to facilitate the placement of insulation materials effectively.
  • As a result of the installation process, the final outcome becomes visible on the interior of the property, potentially influencing room dimensions and overall aesthetics.
  • Internal wall insulation generally offers a more cost-effective alternative compared to external wall insulation, attributed to factors such as materials and labor costs. This makes it an attractive option for property owners seeking efficient insulation solutions.

Cavity Wall insulation is engineered specifically for properties with a cavity wall structure, comprising two distinct layers—an outer and an inner wall—separated by a gap known as the cavity. This insulation method strategically fills this void with insulating materials, effectively enhancing the thermal efficiency of homes and reducing energy consumption.

  • 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, is specifically tailored for older buildings or properties lacking cavity walls, aiming to bolster energy efficiency by applying insulation materials directly to the exterior walls. 

  • Structures erected before 1920 typically feature solid walls, devoid of the cavities found in newer constructions, making them prime candidates for solid wall insulation.
  • Solid wall insulation offers versatile application techniques, including external cladding, rendering (plastering), or installing insulation boards, providing flexibility in implementation.
  • This method proves highly effective in ameliorating energy efficiency and thermal regulation within solid wall properties, contributing to heightened comfort for occupants.
  • The integration of solid wall insulation preserves interior living spaces and upholds the property’s aesthetic appeal, ensuring both functionality and visual allure.
  • It’s essential to acknowledge that solid wall insulation often entails higher costs compared to internal insulation methods, necessitating prudent financial planning for homeowners contemplating this upgrade.
