internal wall insulation

Internal wall insulation (IWI) involves adding insulating material to the inside of your property’s walls. This process is ideal for properties with solid walls or those that cannot have external insulation. By creating a barrier against heat loss, iWI helps maintain a consistent indoor temperature, reduces heating costs, and enhances overall energy efficiency.

  • Condensation control

    Helps prevent damp and condensation on internal walls, reducing the risk of mould and improving structural integrity.

  • Adaptable for All Properties

    Suitable for residential and commercial properties, especially those where external insulation is not feasible.

  • Carbon emissions

    Reduces carbon emissions by lowering energy usage, contributing to environmental sustainability.

  • Warmth & comfort

    Keeps your indoor spaces warmer in winter and cooler in summer, creating a more comfortable living or working environment.

  • Internal wall insulation can reduce heat loss by up to 25%, resulting in noticeable savings on heating bills. Over time, these savings offset the initial investment, making it a cost-effective solution for long-term energy efficiency.

  • Internal wall insulation is a practical and efficient way to improve the thermal performance of your property without altering its external appearance. This makes it an excellent choice for listed buildings, conservation areas, or properties with aesthetic restrictions. Beyond the energy savings, the insulation also enhances indoor comfort and protects walls from moisture damage, increasing the longevity of your property. 

  • Homeowners and businesses looking to reduce energy costs and improve comfort, particularly in properties with solid walls or restrictions on external modifications. Customers who qualify under schemes like ECO4 or GBIS can access financial support for installation. Use our online tool or contact us to check your eligibility. 

  • Our internal wall insulation options include insulated plasterboard, rigid foam panels, and mineral wool. The installation process involves fixing insulation materials to the inside of external walls, followed by a finishing layer such as plasterboard. We ensure a professional finish that blends seamlessly with your interior decor, and our installation team works efficiently to minimize disruption. 

 FAQs

  • Installation typically takes a few days, depending on the size and complexity of the property.

  • Once installed, internal wall insulation is a permanent solution that requires no ongoing maintenance.

  • Internal wall insulation is ideal for solid walls and some cavity walls that cannot be externally insulated.

  • Internal wall insulation may slightly reduce room dimensions, but modern materials are designed to minimize this impact.
