What Is Internal Wall Insulation?

Internal wall insulation represents a highly effective strategy for bolstering the energy efficiency of buildings. It involves the application of insulation materials, such as rigid insulation boards or mineral wool fibers, typically ranging from 60 mm to 100 mm in thickness, onto the inner surfaces of exterior walls.

By introducing an additional thermal barrier within the structural framework, this method significantly reduces heat loss, leading to considerable improvements in energy conservation and decreased heating costs.

This insulation approach offers notable advantages, particularly for properties lacking cavity walls or where cavity wall insulation installation is impractical. Moreover, internal wall insulation contributes to enhanced indoor temperature regulation, thereby elevating occupants’ comfort levels and potentially extending the lifespan of the building’s heating systems.

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 tailored to properties with solid walls, prioritizing the insulation of interior walls within the building.

  • Insulation materials, typically ranging from 60 mm to 100 mm in thickness, often comprise rigid insulation boards or mineral wool fibers.
  • Installation may require the removal of existing wall coverings to accommodate the placement of insulation materials effectively.
  • The resulting improvement is noticeable within the property, potentially influencing room dimensions and visual aesthetics.
  • In comparison to external wall insulation, internal wall insulation typically offers a more cost-effective solution for enhancing energy efficiency.

Cavity Wall insulation offers a tailored solution for properties featuring cavity walls, consisting of an outer and inner wall separated by a cavity.

  • Drilling Process: The insulation process commences with precision drilling into the walls to facilitate the injection of insulation material.
  • Material Injection: Mineral wool or foam is introduced into the drilled holes, expanding to effectively fill the cavity space and enhance insulation.
  • Covering Access Points: Concealment of drilled holes is achieved using plaster or similar materials, preserving the property’s aesthetic appeal.
  • Improved Heating Efficiency: Cavity wall insulation significantly enhances heating efficiency, resulting in long-term energy cost savings.
  • Efficient Installation: Enjoy a swift installation process that minimizes disruption to homeowners or tenants, ensuring a seamless experience.
  • Minimal Disturbance: Cavity wall insulation offers a convenient solution with minimal disruption during installation, prioritizing homeowner comfort.

Solid Wall insulating  serves as a tailored solution for older or solid-wall properties, addressing the need to enhance thermal efficiency. This method encompasses the application of insulation materials to the exterior of the building, establishing a protective barrier against heat loss and elevating the overall energy performance of the structure.

  • Older buildings, particularly those constructed prior to 1920, often lack wall cavities, rendering them suitable candidates for solid wall insulation.

  • Solid wall insulation presents flexible application methods, including external cladding, rendering, or installation of insulation boards. These diverse approaches offer adaptable solutions tailored to various building structures.

  • By effectively improving energy efficiency and thermal regulation, solid wall insulation significantly enhances the comfort levels of occupants within these buildings.

  • Notably, solid wall insulation preserves the integrity of interior living spaces and upholds the aesthetic appeal of properties, ensuring a harmonious blend of functionality and visual attractiveness.

  • Solid wall insulation typically entails higher costs compared to internal insulation options.
