Acoustic polystyrene panels STYRAK EPS T
APPLICATION
- acoustic insulation in floating floors under flooring ground beam
STYRAK panels are specially structurally modified polystyrene, which is applied as acoustic insulation to floors between storeys (residential buildings, hotels etc.). Enables significant reduction of so-called “knocking” sounds (of low frequencies) creating with floor layers (cast concrete floors) so-called floating floors.
