Wall Insulation

Wall insulation is essential for improving the thermal and acoustic performance of any building. By reducing heat transfer through internal and external walls, it helps maintain a more consistent indoor temperature—cutting down on energy use and creating a more comfortable living or working environment.

At Bell Plaster and Building Supplies, we stock a range of high-performance wall insulation products from trusted brands, including Fletcher Insulation Pink Batts for reliable thermal and acoustic control, and Kingspan Kooltherm for premium insulation where higher R-values are required in tight wall cavities. Suitable for new builds, extensions, and retrofits, our wall insulation range supports better energy efficiency and noise reduction across both residential and commercial projects.
