An important function of a suspended ceiling is to conceal plumbing and heating systems, as well as the electrical, telephone and data communications services that are installed in the ceiling void. Many suspended ceilings will need to be demounted totally or partially during their service life when such services are augmented, maintained or repaired. Also, damaged panels must sometimes be replaced.

  • Consider how accessible the void needs to be.
  • Concealed grid and demountability is possible.
  • A special system is available when frequent access to the void is needed.
Plan for maximum demountability
The design of the ceiling tile edges together with the suspension system provides different degrees of demountability. The Ecophon range offers ceiling systems with full demountability, even with concealed suspension systems. However, cable management, ventilation equipment, lighting installations and other features can limit the demountability of individual ceiling panels. These problems can be reduced by carefully planning the ceiling layout and by following the plans throughout the installation. Examples of this can be found in section "Integration".
The Connect T15/T24 Cross tees can be demounted even in the middle of a ceiling area. This is a great advantage when an installation passage is required. 
Accessible space for service
For every system featured in this catalogue the minimum overall depth of system (o.d.s.) and the minimum depth for demountability (m.d.d.) are given.These measurements are also denoted Δ (o.d.s.) and δ (m.d.d.).
The o.d.s. is measured, while the figures for the required m.d.d. are empirically assessed. In practical terms, this means that the measurements might vary slightly depending on the skill and experience of the installer.

Δ = Minimum overall depth of system
δ = Minimum depth for demountability
The overall depth of the system Δ (o.d.s.) is the dimension from the underside of the structural soffit to the underside of the suspended ceiling.
The minimum depth for demountability δ (m.d.d.) is the dimension required, to fit and demount individual ceiling panels. It is measured from the underside of the suspended ceiling.

For frequent access

Hinged ceiling panels (Ecophon Access) are recommended in areas where the services above the ceiling are frequently accessed. These systems provide complete accessibility with no obstructing profiles.
Inspection panels (Connect Inspection panel) are recommended, even in a demountable ceiling, where access to the void is frequently needed, e.g under stop valves.
  • Clean cotton gloves should always be worn to avoid soiling the ceiling during demounting or maintenance work.
  • Avoid placing panels in the void, since they might be damaged by sharp profile edges, etc.
