Melamine Composites with hypalon facing
Is a combination of acoustic foam and loaded vinyl
barrier. This material is a great choice when needing to
block sound from penetrating an area and also helps
dampen reverb.

Great for around generators, and load machinery.
Used a great deal to line the Inside of sound isolation
enclosures, and engine compartments, industrial
partitions and so forth.

GK™ Melamine Composite is a combination of a class
one fire retardant acoustic foam with SoundBlocker1™
vinyl barrier. The surface is a pleasant looking mini
convolution pattern to increase the acoustic absorption
of noises.

GK™ Polyurethane Composite No Facing
is a blend of polyurethane acoustic foam and
SoundBlocker1™ vinyl barrier. This composite is an
economical choice when needing to dampen reverb and
block sound at the same time and no facing is needed.

"GK™ Polyurethane Composite with
  Aluminum Mylar Facing."

This composite combines polyurethane acoustic foam
for sound adsorption and SoundBlocker1™ vinyl barrier
to help block sound all in one product. The aluminum
Mylar surface reflects heat. Additionally the foam will
trap and dissipate mechanical noise generated by
engine components.

GK Duct wrap™ is an excellent thermal and noise
insulator for pipes and ducting. 
This is a high quality product that does the job right.
Also works great as a non-toxic sub-floor 
decoupling and floating floors. Building 
inspectors like this product to help 
block sound between floors and ceilings, 
because if it burns no toxic fumes will be produced.
