Earthwool SoundShield Plus R2.7 SHD Acoustic Batts

When noise is the main problem, density matters. SoundShield Plus R2.7 SHD is a super-high-density glasswool batt that packs more material into the same 90mm cavity, so it absorbs more sound than standard or HD batts while delivering a strong R2.7 thermal rating.

Key benefits

• Super high density for top-tier acoustic performance in a 90mm wall
• R2.7 thermal rating for year-round comfort and lower energy use
• 90mm thickness to suit standard 90mm wall frames
• Non-combustible
• Soft to handle, with a smooth finish on both sides
• Made with recycled glass and a binder with no added formaldehyde

Where it works best

• Home theatres and media rooms
• Music rooms and home studios
• Bedrooms next to living areas or busy roads
• Walls between units or between a home and a garage or workshop

How the 90mm Earthwool wall batts compare

• R2.0: the most coverage per pack and the lowest cost. Earthwool R2.0 Wall Insulation
• R2.5 HD SoundShield: a good balance of price and acoustic performance. Earthwool R2.5 HD SoundShield Acoustic Insulation
• R2.7 SHD SoundShield Plus (this product): the densest, for the best sound absorption in a 90mm frame.

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, and don’t compress the batts.
• Seal gaps around power points and services, since noise travels through them.
• Wear gloves, long sleeves and a dust mask when cutting.
• Check the NCC requirements for your climate zone.

Where it’s not for

They are not recommended as the main insulation for external walls, roof spaces, ceilings under a roof or subfloors, where a higher R-value is needed to keep your home warm in winter and cool in summer. For these areas, choose our Ceiling Insulation Products, and/or Wall Insulation Products, which offer a significantly higher R-value for their thickness.
