We are looking for a modern, non-office looking suspended ceiling system with either a fully concealed grid or ideally panels suspended on wires, being fully demountable as we need access to MVHR ducting and other electrical/water services. Our first floor is wideslab concrete sections, so providing adequate fixing shouldn't be a problem.

We have looked at the usual suspects of Armstrong, Burgess, Ecophon, Knauff etc but they all seem to be directed more to a commercial environment rather than residential. We will need to consider a kitchen and bathroom environment so ideally looking for something which is washable but also with acoustic properties as we have granite flooring and hard plastered walls.

We have looked at an Italian cork panel which is interesting but relatively expensive for our budget. Does anyone have any recommendations that we can consider either in the UK or more likely in Europe?

How often do you expect to have to access the void you create? I would have thought once every other year at most. As you have found I would also expect commercial solutions to be aimed at offices etc. and probably designed on a 600x600 grid with panels sized to fit that.

If your services are not yet in then perhaps design the service runs around the perimeter of the room, then create your own solution with timber framing attached to the ceiling on which you could use plasterboard for the center part of the room with a plywood (or similar material) around the periphery to create removable panels for access. It would not be difficult to disguise the join between the fixed and removable part with decorative architrave (accent coloured perhaps)

If you must have your ceilings washable - I have never washed a ceiling, just redecorated - then use a washable paint.

If you don't want to use plaster board then there are wood wool, straw and clay boards all of which can be finished with lime plaster. I would still suggest your own timber framing with a perimeter service channel.

You would probably need an unwelcome thickness in order to get enough material to T&G, on the other hand if you used AB faced ply the natural colour / look with a clear coat may be acceptable.

Posted By: Petlynthe need for access to ceiling voids with MVHR etc

As has already been asked - how often do you think you'll need access to the ducts or other services?

If ducts need sweeping, it's done from the ends, not by ripping the ducts out. If plumbing or electrics need replacing and you're not willing to take the ceiling down at that time, then run them in conduits and replace from the ends.

Posted By: WillInAberdeenWould you like the kitchen ceiling to be fire resistant? Plaster without joins obvs good for that

Checking the Building Regs approved document B1 (assuming you are in England?) there are some complex requirements for fire resistance of suspended ceilings and the void above, a whole section of Appendix A dealing with them. Seems it must not come falling down in a fire unless it's made of small/lightweight tiles. I don't pretend to understand it, suggest to have a chat with building control.
