Acoustic Reflex 2x3 mm - 35

DESCRIPTION
The complex is made of two 3 mm layers of extruded polyethylene in 35 kg density. Grey to the bottom and white to the top. The top layer is laminated to a layer of HDPE which carries the trade mark ACOUSTICREFLEX®. Using the 100 mm overlap on the top sheet it is overlaid (shingled) in use, eliminating cold spots. Thus it is in total minimum 6 mm and max. 9 mm on the overlap. The material is inert and moisture free, has a high resistance to chemicals and acts as a vapour barrier.

INSTALLATION GUIDE
(In connection with betopor class 1a)

  • The floating planking which should correspond to the technical specification WTCB 189 and 193, is placed on top of the ACOUSTICREFLEX® noting that the final acoustic performance is determined by the quality of the installation.
  • The acoustic layer must incorporate a 100 mm overlap and placed with care to avoid acoustic bridges and particularly with spaces round vertical pipes, doors openings and corners etc.
  • It is advisable to install vertical flanking insulation between the flooring, walls and vertical transitions and the minimum should be at least 20 mm above the final floor level.
  • Once the floor covering is poured out and the planking installed, the superfluous insulation can be trimmed off and the skirting/moldings can be finished incorporating an elastic joint.
