{"product_id":"knauf-earthwool-acoustic-partition-batts","title":"Knauf Earthwool Acoustic Partition Batts","description":"\u003cp\u003eKnauf Earthwool Acoustic Partition Batts are glasswool acoustic batts for partition walls. Knauf sells them as Knauf Insulation Acoustic batts and lists these sizes for metal-frame walls. We stock two densities, 11 kg\/m³ and 14 kg\/m³, each in 50 mm and 75 mm, all 600 mm wide. They are made from glass wool bonded with ECOSE Technology, a plant-based binder with no added formaldehyde.

How much the batts improve a particular wall depends on the overall construction and on the insulation chosen. Where a specific level of acoustic performance is required, BRANZ advises having it evaluated by an acoustic consultant.\u003c\/p\u003e\n\u003cp\u003eBRANZ did not assess the acoustic performance of these batts (Appraisal 873), and the Knauf datasheet gives no sound absorption or Rw figures for them.\u003c\/p\u003e\n\u003ch2\u003eThermal performance\u003c\/h2\u003e\n\u003cp\u003eKnauf's datasheet gives estimated R-values: R1.2 and R1.8 for 11 kg\/m³ at 50 and 75 mm, and R1.3 and R1.9 for 14 kg\/m³. These batts have not been tested to AS\/NZS 4859.1, the standard used to determine insulation R-values, so they do not carry a rated R-value. If the wall also needs a rated R-value, use a batt with a tested R-value, such as \u003ca href=\"\/products\/knauf-earthwool-sound-shield-insulation-batts\"\u003eEarthwool SoundShield\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eGood to know\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNon-combustible when tested to AS 1530.1.
