Composites

Genset Acoustic Foam specialise in the manufacture of various composite materials to suit customers requirements. We have a dedicated spray booth with high pressure spray system. It allows GAF to laminate both single and 2 part adhesive systems. We also fabricate various composites to suit customer’s specifications. These include the following

  • PYROSORB laminated to Profiled XE 440 for super silent generators. Thicknesses vary according to customer requirements
  • PYROSORB Laminated to various substrates including Sonic Liner for oil resistance properties or Sisalation foil paper for heat reflection or air flow resistance
  • XE 440/PYROSORB laminated to 2mm 200 acoustic Barrier for use in heavy duty equipment and marine.
  • PYROSORB laminated to ACOUSTIBLOK makes the best acoustic barrier available 
  • Scruftex
  • Whisper and Pyro

 


PRODUCT: PYROSORB -+ FOIL or SONIC LINER

Pyrosorb

Product Description:

PYROSORB-S class ‘O’ acoustic foam faced with re-inforced aluminium foil or black sonic liner

Product Format:

Sheet material, Standard sheet size 2000 x 1000 mms
Standard Thickness: 25mms. Others available on request. Material can be supplied with Acrylic adhesive backing

Properties:

Foam is a Class ‘O’ acoustic foam

Density 100kg/m³ offers excellent acoustic properties
Thermal conductivity @ 5 C is .0545W/mK (BS874 part 2 1986) See PYROSORB-S Brochure

Facing

Foil has scrim between foil and Kraft paper for added strength
Facing is very low water permeability.
Typical -0.2ug m/(Nh) BS 4370 part 2
Low Surface emissivity i.e. high radiant heat reflection
Fire rating: BS476: Class 1
Sonic liner: Black cloth heat resistant fibreglass cloth

Temperature Range: -40 to +100°C (Continuous)

Usage:

  • Thermal barrier in air conditioning equipment
  • Acoustic lining in bus engine covers

 

External Duct Lagging

 

PRODUCT: 50mm Super Silent Acoustic Foam

PRODUCT DESCRIPTION
25 XE Laminated to DC2, 6mm XE and Screen Foil or 25mm Pyrosorb laminated to 32mm XE440 profiled foam.

PRODUCT FORMAT
Sheet material. Standard sheet size.2000 x 1250 mms.
Standard Thickness: 50 mms.

PROPERTIES

  • Sonic Liner- Black fibreglass cloth
  • Heat resistant
  • Washable
  • 25mm Pyrosorb Foam is Class “O” fire rated foam
  • Density: 100kg/m3 Ideal for sound absorption of both high and Low frequency sound waves. (See attached spec sheet)
  • 25mm XE 440 FRL foam
  • Density: 30kg/m3 self- extinguishing foam (Meets FMVSS 302 spec)
  • Ideal for sound absorption (See attached spec)

TEMPERATURE RANGE: -40 to +120oc (Continuous)

USAGE:

  • Total thickness of 50mm gives excellent sound absorption material properties. Add this to the 2 ideal densities for both high and low frequency wave absorption. This should give a minimum of a 20% drop in Db readings.
  • An ideal acoustic material that is washable should there be any diesel spills within the generator canopy.
