Frequently asked questions about wood removable ceilings

What are wood removable ceilings?

A construction element, generally consisting of removable wood panels which are fixed at a certain distance from the floor and secured thereto by means of profiles and hangers.

What is the difference between removable ceilings and accessible ceilings?

Removable ceilings are those which can be removed although it can only be done by removing wood panels starting from the sides up to the point where you need to work. Accessible ceilings, however, allow you to work on a given location, removing or replacing individual panels without having to move adjoining panels. exactly on a point and can replace a panel in concrete, without moving the neighbouring panels.

Can wood removable ceilings improve the acoustics of a room?

Yes. When sound-absorbent wood acoustic panels are used for the installation of removable ceilings, these help to control reverberation, improving room acoustics.

And what is the sound absorption capacity of these removable ceilings?

It depends on the type of perforation employed to when the acoustic panels are manufactured.

Depending on the type drilling one can distinguish between grooved, circular or square perforations acoustic removable ceilings. Of course, if required, there are also smooth ceilings without any drilling.

As guiding values; since there are many variables that influence the results (plenum, insulation densities, air chamber, thicknesses, etc.), we could review the following:

– The acoustic removable ceilings with circular perforations, they offer (depending on model) an overall average NRC (Noise Reduction Criteria) of 0.55 and an overall average absorption coefficient of 0.43 (0.00 being a lack of absorption and 1.00 total absorption of incident sound).

– The acoustic removable ceilings with grooved perforations, they offer (depending on model) an overall average NRC (Noise Reduction Criteria) of 0.70 and an overall average absorption coefficient of 0.59 (0.00 being a lack of absorption and 1.00 total absorption of incident sound).

– The acoustic removable ceilings with squared perforations, they offer (depending on model) an overall average NRC (Noise Reduction Criteria) of 0.70 and an overall average absorption coefficient of 0.62 (0.00 being a lack of absorption and 1.00 total absorption of incident sound).

And where can these acoustic removable ceilings be used?

Acoustic removable ceilings are widely used in acoustic conditioning projects in offices, meeting rooms, restaurants, auditoriums and other rooms where there are many people at a time and good acoustics is necessary.

What finishes can wood removable ceilings have?

Wood removable ceilings can be finished in wood or colour melamine. We can also opt for finishes in natural varnished wood (beech, oak, maple, cherry, etc.). You can even choose RAL or NCS lacquer finishes or veneering with high pressure laminates (HPL)

Are wood removable ceilings eco-friendly?

They can be if they are manufactured with eco-friendly wood.

Spigogroup has PEFC and FSC certification. These certifications guarantee that the wood used comes from sustainably managed forests and that the wood panel has also been prepared by a manufacturer who guarantees that a PEFC or FSC chain of custody system is maintained right through to the end product.

.Do removable ceilings improve the energy efficiency of a building?

Removable ceilings reduces the power used to air condition the rooms of a building. By lowering the height of the roof, the volume of air which needs to be heated or cooled is also reduced for a given level of thermal comfort. In addition, the air space that forms below the main ceiling also provides thermal and acoustic insulation for the room.

What about the space between the removable ceilings and the original ceiling or plenum, Is it usable?

Yes. This space “left” by removable ceilings serves to house hidden wires and pipes needed for devices in the building’s various installations: electricity, heating, gas, air, sound or safety.

What safety elements can be integrated in removable ceilings?

Among the most common safety elements that we can discover in the removable ceilings are fire-fighting systems, smoke detectors, motion sensors, alarms and security cameras, and other more advanced devices of the latest domotic systems for special buildings.
