Polyurethane Class O Acoustic Foam

Polyurethane Class O Acoustic Foam is a general purpose material that is treated with inorganic fire resisting fillers. It provides excellent thermal insulation properties and is flame retardant in accordance with BS 476 Part 6 and 7, making it suitable for use in buildings as a sound absorptive panel or as acoustic flooring. PU foam does not support fungal growth, offers excellent longevity once installed and is easy to cut and manipulate. The foam is also CFC / HCFC free, non-toxic and is used in a range of industries including; building and construction, automotive, HVAC and manufacturing.

At PAR Group, we supply a range of polyurethane class O acoustic foams that are used in various applications. Popular options include foil faced, for protection against moisture and oils, self-adhesive backed, for ease of installation and affixing, and Melinex® faced, for effective resistance to chemicals and solvents.

Standard (Plain)

Our standard grade of polyurethane class O acoustic foam is designed for general purpose applications and meets the requirements of British building and construction regulations. It is commonly used in a wide range of applications to isolate noise and is a popular material to enclose machinery. It can also be used as absorptive panels in residential, commercial and industrial environments.
 

Self-Adhesive Backed

A polyurethane class O foam with a self-adhesive backing on one side. This option can be easily affixed to a wide range of surfaces and provides the same characteristics as the plain faced alternative. 
 

Class O Foil Faced

A foil backed acoustic foam that is popular in marine applications or on duct linings (HVAC) when a polymeric sound barrier is required. It can be easily cleaned and offers effective resistance to moisture and oils due to the facing.
 

Melinex® Faced

Melinex® faced (polyester film) acoustic foam provides an effective layer of resistance to chemicals, solvents and temperatures. The film does not limit the sound insulation capability of the material.
 

SVG1 Vinyl Glass Cloth Faced

A flame retardant, SVG1 glass cloth faced polyurethane acoustic foam that provides effective resistance to a wide range of chemicals. It can be easily cleaned and is commonly used in areas where high levels of cleanliness are required.
 

200gsm Woven Glass Cloth

Providing enhanced resistance to temperatures due to the woven glass cloth facing, this option is commonly used in environments that require heat deflection.
 

S-V1 Polymeric

A polyurethane acoustic foam with an S-V1 polymeric coating that provides effective resistance to aromatic hydrocarbons and moisture. This option is popular in automotive applications, engine rooms and HVAC systems to help isolate noise.
