These recommendations are for general guidance only. Installation methods must be tested under actual service conditions to determine their suitability for that particular purpose.
Spray-on or roll-on adhesives
Soundmesh G8 can be glued on with spray-on adhesive or roll-on adhesive.
We recommend applying this type of adhesive onto the substrate only. If the glue is to be applied onto the Soundmesh G8, then use only a light coating of adhesive spray. An excessive amount of glue on the Soundmesh G8 will affect the acoustic performance.
Staple with a staple gun
Soundmesh G8 must be fully tensioned before applying the staples. Photos below show typical applications.
Important note: the acoustic performance will be affected if the Soundmesh G8 is not fully tensioned.
Soundmesh G8 tensioned, to be flat and smooth
Soundmesh G8A consists of two key components as shown below:
- Soundmesh G8 base acoustic fabric (black) and
- Heat reactive web adhesive (white)
The heat reactive web adhesive is pre-attached onto the Soundmesh G8 base fabric.
Important note: do not remove this web adhesive from the Soundmesh G8 base fabric.
The melting temperature is approximately 115°C for the heat reactive web adhesive. Once activated, the web adhesive changes from white to transparent /clear.

Note: this web adhesive can also be reactivated with heat.
The Soundmesh G8 based fabric has excellent thermal insulation properties. The required heating temperature may need to be much higher than the melting temperature in order to activate the heat reactive web adhesive.
Recommended methods to bond the Soundmesh G8A onto perforated / slotted panels
- The surface of the perforated/slotted panels must be clean and free of oil, moisture, dust and any other contamination. Clean the substrate surface with Megasorber AC5 adhesive cleaner or equivalent.
- Ensure panels are flat and have an even surface.
- Panels with glossy, mirror-like surfaces and powder coated metal panels: The heat reactive adhesive does not suit these surfaces. In order to create bonding, it is recommended to sand or roughen up the glossy surfaces, then clean the surface with Megasorber AC5 or equivalent.
Heating and temperature:
- Pre-heat the substrates and the Soundmesh G8A to around 140ºC before bonding.
- Once the heat-reactive web adhesive changes from white to transparent, it indicates that the heating temperature reaches the required bonding temperature.
- If the heat-reactive web adhesive remains white after the bonding process, it indicates that the heating temperature needs to be increased.
Infrared heating unit with press rollers: Heat the G8A with the perforated or slotted panel with infrared radiator and press by using a roll. One of the typical applications is shown below:

A nipping machine with infrared heating or hot rollers: Activate the G8A heat-reactive adhesive with the infrared heating or hot rollers and bond the G8A onto the panel via feed rollers.
Ironing press: Set ironing press at 150°C to 170°C, with 200 to 250 mbar pressure for at least 10 seconds residual time.
Hot iron: Set the hot iron to maximum temperature, typically between 150°C to 175°C, and iron the G8A onto the back of the perforated or slotted panel with firm pressure.
