Earthwool® R2.0 Wall Insulation Batts (90mm)

If you’re insulating the walls of a new build, extension or renovation on a sensible budget, Earthwool R2.0 wall batts are a straightforward choice. At 90mm thick, they fill a standard 90mm stud cavity, and the compression packing means each bag covers a lot of wall.

Key benefits

• R2.0 thermal rating for wall cavities
• 90mm thickness to suit 90mm wall frames
• Large coverage per pack, so fewer trips and a lower cost per square metre
• Absorbs noise passing through walls
• Non-combustible
• Soft, easy to cut and install

Standard or HD?

Both are R2.0. The standard batt is 90mm thick and softer, with more coverage per pack. The HD batt is 75mm thick and denser, with fewer square metres per pack. Choose the one that suits your frame depth and budget. Earthwool® R2.0 HD Wall Insulation 

Installation tips

• Follow the Knauf installation instructions for wall batts. Earthwool® Wall Installation Guide
• Cut batts slightly oversize so they friction-fit between studs.
• Fill the cavity fully, without compressing the batts.
• Wear gloves, long sleeves and a dust mask when cutting.
• Check the NCC requirements for your climate zone.
