Insulation for Internal Timber Stud Wall
U-value CalculatorStart your U-value calculation >
The primary purpose of an internal timber stud wall is to provide acoustic separation for airborne sound between two adjacent rooms within a dwelling, thereby improving the acoustic comfort of those within the dwelling.
The minimum permitted acoustic specifications are defined by Approved Document E (England & Wales) and Section 5 (Scotland), although it is often recommended to improve on this where possible.
These walls are typically constructed using timber studs placed at nominal 600mm centres finished with a sheet of plasterboard to each side. The insulation of choice for internal timber stud walls is typically a glass mineral wool (GMW) roll or slab. ISOVER Acoustic Roll (APR 1200) can be installed as part of the internal timber stud wall construction between the studs to provide the level of sound reduction required according to Approved Document E (England & Wales) and Section 5 (Scotland).
