The stone wool slab with a nominal density of 60 kg / m3 is intended for acoustic and thermal insulation of ventilation ducts, expansion boxes, filling of acoustic silencers, screens, cassettes and sound absorbing panels as the internal damping layer in ventilation devices. The external coating of the plates (glass veil in black) is adapted to air flow at a speed of 20m / s without causing the fibers to be entrained.
Maximum temperature of the thermal energy carrier: 250oC.
WARNING!!! The Invent N3 board has a protective veil on one side. Plates covered with a veil on both sides have the Invent N3 / N3 designation.
