ISO NOISE Premium
High-quality polyester-fiber sound insulation batt wrapped in a clear PE bag; non-itchy and dust-free. Inside a wall cavity it gives the same sound-insulation benefit as the Standard batt, and because it tolerates water and humidity it is commonly used for exterior sound-insulating walls and noise barriers.
- Polyester fiber — non-itchy, dust-free
- Tolerates water and humidity
- Commonly used for exterior walls and noise barriers
Premium and Standard give the same sound-insulation benefit inside a wall cavity. Premium tolerates water and humidity, so it suits exterior work.

Sound absorption coefficients of the material
The values below describe the sound absorption of the material itself. They are not the sound insulation of a wall — sound insulation (STC) is a property of the complete wall system.
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 | NRC |
|---|---|---|---|---|---|---|---|
| Absorption coefficient | 0.12 | 0.59 | 0.65* | 0.90 | 0.86 | 0.89 | 0.76 |

Performance inside a wall system
According to the supplier, filling the cavity raises the sound insulation of lightweight and double-leaf masonry walls by about 7–10 dB compared with the same wall with an empty cavity, without adding wall thickness or weight.
The result on site depends on every part of the system: board type and number of layers, framing, cavity depth, joints, doors and windows. The batt on its own has no STC rating.

Installation
- Fit the batts, still in their clear PE bags, to fill the whole area of the lightweight wall or double-leaf masonry wall. No adhesive is needed.
- Where the wall does not match full sheets, cut the batt to fill the remaining area. No adhesive or tape is required.
- Close the cavity with a solid layer such as gypsum board, fibre-cement board or brick so the wall system can block sound.
