  1. SOUND INSULATION IN CIVIL BUILDING Table of contents • Sound impact & airborne insulation • The acoustic in building • Job-site surveys • Machinery and plant insulation • Our products • Services • Something about the competition

  2. Sound impact insulation To reduce the impact noise heavy structure with high mass are not required but the basic concept is the ELASTICITY of the system. A Flooring finishing B Screed C dBred F10P roll D Lightweight mortar type POLITERM BLU E Slab F Ceiling plastering finishing

  3. Dividing wall composed of two hollow-bricks with inbetween a dbred W sound insulation panel Mettere foto fatta in cantiere dai VVF

  4. dBred strip dBred strip Disconnection with anti vibration pads or strips between wall and floor

  5. Air borne sound insulation A Wall plastering finishing B Brickwall C Plastering/gypsum board D Panels type dBred W20 E Stripe type dBred F5

  6. WALL COVERING FOR A BETTER ACOUSTIC INSULATION A Gypsum board panel B Existing wall C dBred type W 10 D Rockwool E Studs F Stripe type dBred F5

  7. FALSE CEILING FOR A BETTER ACOUSTIC INSULATION A Slab B Existing wall plastering C Anti vibration hanger D Rockwool / Polyester fibre E Gypsum board F dBred type W 10 G Perforated gypsum board
