Assembly set weber.projekt Iso-Bar

weber.projekt Iso-Bar is a thermally separated fastener with a M12 metric neck tread of stainless steel and an additional sealing element. It is anchored using injection mortar and it can be fixed into concrete as well as into solid and perforated masonry stones.

For the retro-fitting of medium-heavy to heavy attachments to facades with ETICS, e.g. sunblinds, porches, railings for plants, consoles for air conditioning units.

Subsequent fastening of heavy fittings

  1. Pre-drilling

    Always first carry out a pre-drilling (centring hole Ø8 or Ø10 mm)!

    Concrete, solid stone and block stone, perforated and hollow stone: hammer drilling.
    Masonry brick, vertically perforated brick, lightweight solid stone, lightweight hollow block: only rotary drilling!

  2. Drilling of boreholes

    Afterwards, drill the actual hole.
    (drill hole diameter Ø = 24 mm / 26 mm*)
    (drill hole depth h = minimum 50 mm / 100 mm*)

    *Hole diameter and depth depend on the wall material. See approval documents.

  3. Information on borehole diameter and depth

    Anchorage in concrete (with and without cracks)

    • Drill hole diameter in concrete: d0 24 mm
    • Minimum anchorage depth: hef min. 40 mm
    • Drill hole depth h1: hef + 10 mm

    Anchoring in masonry

    • Drill hole diameter: d0
    • Solid building material without perforated sleeve: 24 mm
    • Solid and perforated building materials with perforated sleeve: 26 mm
    • Minimum anchorage depth hef:: minimum 80 mm
    • Drill hole depth h1: hef + 20 mm
  4. Borehole cleaning

    Clean the borehole thoroughly. First blow-out the dust with the pump (4 times)...

  5. ...subsequently, brush out with the brush, and...

  6. ...blow out again 4 times with the blow-out pump.

  7. Cut to length

    The weber.projekt Iso-Bar is cut to length on site. Use a cutting disc.
    Do not shorten with a bolt cutter!

  8. Length
    The thickness of non-loadbearing layers
    (for ex. render, reinforcement layer, insulation board, adhesive, etc.)
    mandatory anchoring depth hef


    Necessary anchoring depth
    • Concrete: hef, minimum 40 mm
    • Masonry: hef, minimum 80 mm
  9. Milling out

    The render is milled out with the attached installation tool. The weber.projekt Iso-Bar is screwed in up to its collar (end stop) and then removed again.

  10. Injection of mortar

    The drill hole in the wall material is filled with the injection mortar belonging to the system.

    (The photo shows the application without a sieve sleeve. Depending on the wall material, a perforated sleeve must be inserted into the drill hole prior to the mortar injection - see official approval.)

  11. Note: make sure that the mortar is used in the correct mixing ratio and discard the first 10 cm of mortar bead from each new cartridge.

  12. Screw -in weber.projekt Iso-Bar

    Screw-in the weber.projekt Iso-Bar with the help of the attached installation tool until its collar as end stop is in contact with the render surface.

  13. Curing time

    The installation tool is only removed after the injection mortar has hardened.

  14. Defined centring

    Easy to see after removal: thanks to the installation tool, the weber.projekt Iso-Bar is perfectly centred. The collar is flush with the render surface.

  15. Attachment of add-on part

    Now, the assembly of the specific add-on part follows. First, the sealing element is placed on the thread attachment. Finally, secure the add-on part with the washer and the hexagonal nut M12.

  16. Completed installation

    The weber.projekt Iso-Bar allows a constraint-free movement of the assembled elements under load.

  17. Ready!
