Ceiling hangers are a good choice where are able to lose 85mm-91mm ( or about
3 inches) of ceiling height. It is the least intrusive method of sound insulating
your ceiling, as it is relatively mess free. This is particularly the case where
you have existing lath and plaster ceilings and don't want the mess of removing
the old ceiling.

and all our other soundproofing solutions. Contact us for more details.
Lath and platter ceilings tend to be good soundproofers from the airborne perspective
and similar to a double layer of plasterboard. Hence keeping them will not only
reduce the mess but also mean a better final level of soundproofing. Remember
that lath and plaster ceilings can be more unstable than plasterboard ceilings,
(especially if water damaged) and this might affect your decision on ceiling
retention.
Important note on recessed lights
If you are adding recessed spotlights in this ceiling you will need to add an acoustic fire retardant light hood to each light, otherwise your soundproofing efforts will be severely compromised due to the hole you have created. These can be purchased from our on-line store.
The method for installation is straightforward.
- The joist lines of the existing ceiling is located, either via a joist finder sold at B&Q etc) or by carving into the ceiling.
- Along the joist line starting from one end you affix an acoustic hanger. Hangers are screwed into the joists at max 800mm centres across the length of the joist.
- Wooden battens are threaded through the joist hangers
- A Flexi edged mineral wool layer is affixed between the battens.
- A Double plasterboard layer is affixed to the battens and the perimeters sealed.
- Any spotlights placed in this ceiling will require acoustic hoods.
