1.1 General advises

 

  • Usable subsoil are flat solid ceilings or walls made of mineral building materials or suspended mineral ceilings
  • The subsoil examination must be carried out in accordance with the valid normation (SIA V242, DIN 18350 or ÖNORM B3346).
  • Loose plaster layers, paint coatings must be removed, defects and larger unevenness in the substrate must be covered/filled with suitable material, for example with a lime cement plaster.
  • All penetrations (for example electrical installations) through the panels must be hermetically sealed at the end sides.
  • Dilatation joints on suspended systems or solid ceilings must be taken over in the acoustic system.
  • Plate joints in the structure must be filled in Q2 quality
  • The subsoil must be dry, clean (free from grease and dust), flat smoothed, free from efflorescence and separating agents such as form work oil etc.
  • The adhesive tensile strength of the subsoil must be at least 0.5 N/mm2.
  • The temperature of subsoil and ambient must be at least +5°C and must not exceed 30°C.
  • No rising moisture in masonry.
  • In case of building renovation, the planned works must be examined by a specialist in terms of building physics.
  • The corresponding projects are to be considered and checked by a construction-physicist under the point of view of condensation water etc.
  • For subsoil with high absorption capacity such as plasterboard, a filling primer must be painted first.
  • Smooth concrete surfaces must be pre-coated with a bonding agent.

  

1.2 Connections to adjoining components

 

  • All adjoining components (lamps, light switches, plugs etc.) must be separated from the panels by a separating paper strip. After the final coating (Fluraphon Top) this paper strip must be cut with a clean cutter.

  

Attention:

 

  • For a clean corner design, the separation tape must be cut in the corners and not be pulled out over the corners.
  • PE-Foam strips are not suitable, because they cause an un-sharp edge when cut.
  • Penetrations through the absorber panels (lamps, ventilation inlets and outlets, cable etc.) must be hermetically closed. This can be achieved by filling the penetrated panels with a flexible adhesive front side wise.

  

2.     Mounting the EcoSana panels

 

        2.1 General 

 

  • The panels must be stored and processed under dry conditions.
    Damp panels are to be disposed.
  • The panels are not suitable for structural use.
  • Damaged panels must not be used.
  • Installation elements or breakthroughs, where temperatures of more than 80 ° C are to be expected, must not be installed in the panels without additional fire protection measures. Penetration in the acoustic ceiling must always be coordinated with the fire protection officer
  • Mounted panels must be protected against moisture.
  • Insulation material cutting knifes or the “insucut circular knife” by Kaindl are suitable for cutting the panels.
  • Milling cuts for the cable or pipe installations in the absorber panels can be carried out quickly and easily with a router or alternatively with a cutter.
  • Because of the fiber dust when working with fiber insulation panels, a extraction by vacuum cleaner and wearing of a dust mask is strongly recommended.

  

      2.2 Gluing of panels

 

  • The use of mix mineral glue (for example Fluren-Flexkleber C2TE) according to the manufacturer’s instruction is recommended. The use of gypsum plaster is not permitted.
  • The glue will apply with a 6 x 6 mm tooting trowel on the soft (without embossing) side of the panel.
  • On uneven surfaces a simultaneous partial leveling of the subsoil (wet in wet bonding is necessary.
  • Then the panels are pushed in and pressed firmly against the ground and the preceding panels. If the panels cannot be moved, tap them with a rubber mallet to ensure a secure bond to the subsoil.
  • If the EcoSana panels are used in combination with Naturo panels, the front ends should be glued together with the flexible adhesive during the material transfer.
  • After setting the panels, the emerging glue from the side should be removed immediately.
  • The panel joint should fit in joint less.
  • The vertical panel offset must be at least 25 cm. Cross joints are not allowed.
  • Panel joints in extensions of window areas should be avoided in order to prevent cracks. Remaining pieces of absorber panels smaller than 20 cm should be mounted in the plane surface and not at the connection to the wall.
