How to install Silentwall®
- Apply the glue to the wall that is being insulated (0.25 L/m2).
- Always use the Recticel adhesive for acoustic insulation panels.
- Check the position of the panels before applying the adhesive. The glue holds immediately and instantly (it is impossible to reposition after the initial contact).
- To cut Silentwall panels, use a snap-off blade knife (cutter blade).
- Apply the glue to one side of the Silentwall (0.25 L/m²) and wait 10 to 30 minutes. Do not glue the edges of the Silentwall® panels, but make sure they are flush against each other.
- Place the Silentwall® panel on the wall, press firmly for 30 seconds.
- Apply the adhesive to the plasterboard (0.25 L/m²).
- Apply the adhesive to the visible side of the Silentwall® (0.25 L/m²) and wait 10 to 30 minutes.
- Place the plasterboard onto the Silentwall® and press firmly for 30 seconds. The plasterboard sheets need to be about 2mm from the floor, adjoining walls and ceiling. The gap should be filled with acrylic mastic.
