Warrington Fire
Certificate type
Acoustic enclosure and acoustic lining insulation. The foam laminates are a highly efficient acoustic treatment for acoustic enclosures, ductwork, engine housing, and infills for suspended ceilings.
Application
A highly efficient acoustic treatment for ductwork, suspended ceilings, infills for partitions between offices, acoustic enclosures and similar outer treatment applications where a considerable reduction in the passage of breakout noise is required.
Description
A flexible material available in a range of formats to suit consisting of a four part laminate, incorporating two spacer or isolating layers, a heavy mass absorptive layer and an outer flame/ vapour barrier meeting Class ‘O’ of the UK Building Regulations. Being of a laminated construction it overcomes the need for a separate isolation layer normally required beneath most forms of acoustic lagging or isolated acoustic barriers.
Acousti-lag FL-B uses a polymeric heavy mass barrier material of either 5 kg/m² (WB5) or 10 kg/m² (WB10) surface weights. It is a composite of two layers of INS Class “O” Polyurethane Non-Flammable Acoustic Foam, with an inner isolated layer of heavy mass barium sulphate loaded polymeric barrier.
Features and benefits:
- Easy and quick to apply.
- Excellent acoustic performance.
- Applied as a single layer treatment.
- Excellent fire resistance and temperature stability.
- Available in various formats to suit application.
- Low thermal conductivity.
- Low toxicity.
