INS (Class ‘O’) Acoustic Foam Facings
INS Class O acoustic foam with an S-V1 coating is employed where a resistance to fluids and chemicals is required. Ideal for clean room and computer room applications where a dust free environment is specified. Where INS Class O acoustic foam is used for internal and external duct linings, the S-V1 surface treatment provides an effective barrier to water especially at ductwork inlet sections. S-V1 is applied to INS Class O acoustic foam for engine room applications such as under bonnets and in engine compartments.
- Fire resistant polymeric coating
- Surface can be easily wiped clean
- Improves durability
- Provides resistance to water, oil, petrol, diesel, and detergents
- Large improvement to mid frequency acoustic performance
Fire Retardant Acoustic Foam Type FR25
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.
- 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
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 equired beneath most forms of acoustic lagging or isolated acoustic barriers.
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.
- 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
