R2.5 HD Pink Batts Acoustic Wall Insulation
R2.5 HD Pink Batts Acoustic Wall Insulation is a high-density glasswool batt from Fletcher Insulation providing thermal and acoustic performance in 90 mm wall cavities. The HD formulation at R2.5 makes it a common choice for internal walls where acoustic separation between rooms is a priority alongside thermal compliance.

Used in external and internal stud walls during construction, before internal linings are fixed. Typical installations include walls between bedrooms and bathrooms, external walls facing high-noise areas such as roads, and internal partition walls where acoustic separation is required. Suits timber and steel stud framing. The R2.5 rating also meets thermal requirements in cooler Australian climate zones where higher external wall R-values are specified.

Holds CodeMark Certificate of Conformity CM 30006. The glasswool carries FBS-1 Bio-Soluble Insulation classification. Non-combustible and low allergen.
Frequently asked questions
When would I choose R2.5 HD Pink Batts over R2.0 HD for internal walls?
The R2.5 HD provides greater density and thermal resistance than the R2.0 HD at the same 90 mm thickness. It is suited to situations where the specification calls for R2.5, or where higher acoustic performance between internal rooms is the design goal.
Does the HD formulation improve acoustic performance?
Yes. The higher-density HD formulation provides greater sound absorption than standard-density glasswool batts of the same thickness, making it more effective at reducing sound transfer through wall and floor systems.
Which width suits standard Australian stud frames?
Four widths are available: 430 mm and 580 mm for imperial-spaced stud centres, and 450 mm and 600 mm for metric-spaced centres. Select the width matching your frame spacing so the batts fit snugly without cutting.
