DUMP CR 400DescriptionHigh acoustic insulationfor double wallsDUMP CR 400 is an acoustic and thermal insulation panel composed ofa layer of CLASS 1/F1 polyester fibers coupled with an elastomeric highdensity barrier (EPDM). DUMP CR 400 is also available in an adhesiveversion with water-based acrylic glue, to support the installer in the layingphase.ApplicationsDUMP CR 400 is ideal for a thermoacoustic insulation of walls andceilings using a single panel that can be easily inserted within the studsof drywalls (plaster, wood, magnesium) and placed right against the dropceilings.LayingFor the application within dry walls, we recommend to place the productinside the wall studs and to tape horizontal seams between adjacent panelswith MAPPYTAPE TXT adhesive (page 98) to avoid possible acousticbridges. If you use a thickness less than that of the stud, we recommendthe use of our MAPPYCOL S45 adhesive (page 96) as support to the wall,for example using an insulator thickness of 30 mm with a 50mm stud.Within drop ceilings lean the product against the internal surface.DUMP CR 400 can be cut using a cutter.RenovationsHollow brick(thick. 8 cm)PlasterDUMPCR 400StudPOLISTIKDoubleDrywallPlaster32
