    2.3 ON-ROOF SUPPORT


    On-roof supported silencers are mounted on the roof via mounting brackets,
    either directly (in-roof installation) or through stays of suitable length (roof-top
    installation). This option is especially relevant for large and heavy silencers and
    installations in high-wind areas.
    To allow for thermal expansion effects, the blow-off piping can alternatively be
    flexibly suspended, allowing it to move relatively to the fixed vent silencer, or a
    length compensator can be integrated in the silencer. Available standard
    compensator options include metallic pipe expansion joints or GLAUNACH’s
    special “Sliding Diffuser Silencer” layout:

    left: thermally expanded state, right: contracted state

    GLAUNACH sliding diffuser vent silencers are also eminently suitable for
    installations requiring noise decoupling between the vent silencer and solid-
    borne sound in the upstream installation.

    2.4 FLEXIBLE SUPPORT


    The flexible support is a special on-roof support, in which the silencer is mounted
    on balancing bearings. This design allows for axial movement, in particular
    caused by thermal expansion, while still providing full structural support of the
    vent silencer.
    NOTE: In this design, residual powers may be perpetually exerted on the pipe.

    3. DEWATERING
    For draining rain water and condensation, each GLAUNACH silencer is equipped
    with a non-pressurised dewatering pipe at the bottom of the silencer shell.

    The dewatering pipe may be left open, or connected to a drain system.

    CAUTION: Drained condensate may be hot. Where this may be the


    case, we recommend collecting the liquid into a drain system, or
    provide a drip plate or cup under the dewatering pipe to prevent
    long-term damage to the roof.
