#### 󠀁[Characteristics](https://uzbuild.com/en/acuflex/#1704280275702-aa3f1cf6-5a58)󠁿

 * **Packaging** Roll width: 1 m Roll length: 15 m Thickness: 4 mm Roll weight: 
   5.0 kg **Physical and technical characteristics**
    - Surface density: 300 g/m2
    - Breaking load along the length and width: not less than 750 N
    - Thermal conductivity coefficient (λ), W/m ̊С: 0.036
 * **Reduction of the reduced impact noise level:**
    Impact noise reduction:
    - under a 15 mm parquet board: ΔL _(nw) = 17 dB
    - under 8 mm thick laminate: ΔL _(nw) = 20 dB
    - under a cement-sand screed with a surface density of 120 kg/m2 with a separating
      layer: ΔL _(nw) = 28 dB;
    - under a cement-sand screed with a surface density of 120 kg/m2 without a separating
      layer: ΔL _(nw) = 24 dB;
    - under a 20 mm thick KNAUF floor element with 8 mm thick ceramic tiles laid
      on top: ΔL _(nw) = 21 dB.
 * Tests were performed by the acoustic measurements laboratory of the Scientific
   Research Institute of Physics of the Russian Academy of Architecture and Construction
   Sciences in Moscow and the acoustics laboratory of the Nizhny Novgorod State 
   University of Architecture and Civil Engineering (NNGASU) in Nizhny Novgorod.
   The material’s performance was verified under natural conditions.
 * 
   #### The standard value of the impact noise index for floors between apartment rooms is Lnw ≤ 60 dB. (SP 51.13330.2011)

 * Instructions for installing Acuflex under a screed to form an edge layer (with
   an extension to the walls).
 * When constructing a soundproof floor structure, the following materials are used:
    - Soundproofing underlay Acuflex;
    - Construction tape;
    - Reinforced polyethylene film;
    - Cement-sand mixture for screed construction of grade not lower than M300;
    - Reinforcing mesh with a cell size of 50×50 mm and a rod diameter of 4 mm.
 * The structure consists of a layer of reinforced cement-sand screed at least 60
   mm thick laid on Acuflex soundproofing material. Acuflex rolls are laid on the
   ceiling across the entire floor area of the protected space and are then inserted
   vertically onto the wall to ensure acoustic decoupling of the screed from the
   walls.
 * A detailed soundproofing floor installation technology is provided in [the Engineering Solutions Album (September 2021, issue](https://www.acoustic.ru/ref_book/albums/airzk/)

   more information on design and installation, [see https://www.acoustic.ru/constructions/zvukoizolyaciya_pola/30/](https://www.acoustic.ru/constructions/zvukoizolyaciya_pola/30/)
 * Instructions for installing Acuflex under the finishing coating (without mounting
   it on the walls):
 * The following materials are used in the construction of the structure:
    - Soundproofing underlay Acuflex;
    - Construction tape.
 * Akuflex rolls are rolled out over the entire floor area of the protected room
   without being placed on walls and columns.
