Stud Wall Insulation

About

Stud Wall Insulation Stud wall insulation is essential for improving the thermal and acoustic performance of timber and metal stud partition walls, both in new-build and renovation projects. Whether you're insulating an internal partition to reduce sound transmission between rooms, or an external stud wall to meet Building Regulations U-value targets, we stock the right products for the job. Types of Stud Wall Insulation The best insulation for a stud wall depends on whether your priority is thermal performance, acoustic control, or both: PIR rigid boards — high thermal performance in a slim profile, ideal for external stud walls where U-value targets must be met with limited wall depth Mineral wool slabs — excellent acoustic and thermal properties, easy to friction-fit between studs, and widely specified for both internal partitions and external walls Acoustic insulation slabs — higher-density mineral wool designed to maximise sound reduction between rooms and floors Meeting Building Regulations External stud walls in new builds and extensions typically need to achieve a U-value of 0.18 W/m²K or better under Part L of the Building Regulations. Our product pages include full thermal data to help you specify the right thickness and type for your project.
