Ceiling Hanger VT-ACC

The Vibratec acoustic ceiling connector VT-ACC is designed for easy installation and good performance. The connector/hanger is made of galvanized steel and it will deflect under load as a symmetrical leaf spring.

Product Characteristics

Unlike our other suspended ceiling systems, VT-ACC have a fixed height of about 47mm including the 50x15mm rail (excl. deflection). If adjustable height is required we refer to our systems VT-SFC or VT-CBC.

When installed according to the specifications table the system will deflect approximately 3mm resulting in a resonance frequency of approx. 10 Hz. To keep the acoustic ceiling connector in its elastic zone and avoid plastic deformation the connector should not be overloaded.

Product Applications

Suspended ceilings – perfect when room to suspend the inner ceiling is limited.

 

Installation Guidelines

  1. The acoustic ceiling connectors are screwed to the existing ceiling in straight lines – recommended distance between hangers and rails according to the table below (columns P and G). For higher loads and other configurations contact Vibratec for support.
  2. When the acoustic ceiling connectors are in place, the rails can be installed with a simple click and plasterboards are screwed onto the rails.
  3. Mineral wool should be used in the air void to absorb possible standing waves in the void. VT-ACC hangers must only be used with Vibratecs profile rails to ensure structural stability of the ceiling.
  4. Self adhesive elastic strip VT-Strip can be used to isolate the suspended ceiling from surrounding walls to avoid undermining the acoustic integrity of the ceiling. Fireproof acoustic sealant VT-FAS can also be used.

This table could be used for ceilings without additional hanging load. 45mm standard mineral wool is included in the calculation, giving approx. 12 kg/connector. For other ceiling materials, heavy insulation or attachments to the ceiling, please contact Vibratec for advise.
