Acoustic Fill
The acoustic fill used in traditional acoustic louvres has been mineral/ rock wool with a tissue face to limit the migration of loose fibres.
QEF have made the decision to avoid the use of mineral/ rock wool due to the health and safety issues arising during the manufacturing process in the first instance. Secondly, the use of mineral/ rock wool in certain facilities is becoming more restrictive due to the potential risk of fibre migration.
QEF has chosen to use Polyester Blend acoustic fill for our acoustic louvres as it offers significant advantages, namely:
- Non-irritant & non-itch material that is free from floating fibres or dust and so avoids skin irritation and respiratory problems normally associated with other forms of insulation
- User-friendly- no protective clothing required by users
- No concerns regarding it being a Group 2B Carcinogen
- Moisture tolerant – no concerns with moisture affecting thermal or acoustic properties
- Mould resistant
- Manufactured from 75% recycled material
- Fully recyclable
