Fire Retardant Acoustic Foam Type FR25

Acoustic Foam Type FR25.pdf

Applications

INS FR25 acoustic foam is typically used for machinery enclosures, doors, walls, partitions and air conditioning ducts. It is also ideal for insulating cabs of industrial vehicles and enclosures for vehicle and boat engines. For wall and machinery enclosures, the acoustic performance of INS FR25 can be dramatically enhanced when used in combination with DS damping sheet. FR25 is a non-dusting and flexible acoustic foam that provides excellent sound absorption.

Benefits

  • Available in sheet form.
  • Flexible and easily cut.
  • Easy to handle and install.
  • Suitable for curved surfaces or complex shapes.
  • Available with a self-adhesive backing.
  • Available with various backings including self- adhesive backing


INS Acousti-lag Foam Laminates

Acousti-lag Foam Laminates.pdf

INS Acousti-lag FL incorporates a spacer or isolating layer, a heavy mass layer, an absorptive outer layer, and an outer flame / vapour barrier which meets 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.

Applications

INS Acousti-lag FL Foam Laminates are a highly efficient acoustic treatment for ductwork, suspended ceilings, infills for partitions and baffles between offices, enclosures and similar outer treatment applications where a considerable reduction in the passage of breakout noise is required.

Benefits

  • Easy and quick to apply
  • Excellent acoustic performance
  • Applied as a single layer treatment
  • Excellent fire resistance & temperature stability
  • Available in various formats to suit application
  • Low thermal conductivity
  • Low toxicity


INS Acousti-lag Pipe Lag Type FL

INS Acousti-lag Pipe Lag Type FL.pdf

INS Acousti-lag Pipe Lag is a well proven product consisting of a four part laminate including two acoustic isolating layers or spacers of INS PolyUrethane Non-Flammable Class ‘O’ acoustic foam, separated by a heavy mass layer of acoustic grade lead or polymeric barrier, with a facing of Class’O’ reinforced foil. Acousti-lag Pipe Lag is available in a range of formats by varying the weight and type of the mass barrier and also from a selection of three thicknesses of acoustic spacer layers to suit the performance required.

Applications

INS Acousti-lag Pipe Lag is a highly efficient acoustic treatment designed for rainwater pipes, pneumatic and hydraulic pipes, and waste water pipes for industrial, commercial and construction applications. Steam pipes can also be treated with INS Acousti-lag Pipe Lag providing a suitable thermal insulation is applied as a first layer. Being of a foam laminate construction, it is ideal where fibre erosion is not acceptable and where a significant reduction in break out noise is specified.

Benefits

  • Easy and quick to apply
  • Excellent acoustic performance
  • Applied as a single dry treatment
  • Excellent fire resistance and temperature stability
  • Low thermal conductivity and low toxicity
