HTPL – Sound insulation side plate
The HTPL-100 Impact Sound Insulation Plate is a lightweight PE foam filler designed to create an effective acoustic separation between stair or landing elements and adjacent walls. Installed at the joint interface, it prevents the transmission of impact sound while avoiding the formation of acoustic bridges. The closed-cell foam also prevents dust, debris, and concrete particles from filling the joint. As a non-load-bearing material, the HTPL-100 serves solely as a filler and acoustic isolation layer.
For easy installation, the entire surface of the plate is covered with a white, self-adhesive, double-sided foil.
Its self-adhesive surface enables quick installation, and the material can be easily cut to size on site or in precast concrete production facilities.
Filling the joint with an insulation board such as Halfen HTPL is essential to ensure the acoustic performance of the entire system. Leaving the joint open may allow dust, debris or small construction particles to accumulate, creating acoustic bridges that can compromise the effectiveness of the installed acoustic elements.
