Metal Ceiling Products

 

DeAmp’s Architectural metal ceilings are completely fibre free and ensure a better indoor environment and easy maintenance. Since there is no use of porous layers, there is no risk of dust or moisture problems over the lifespan of the product or in a fire emergency. The perforation covers less than 1% of the panel surface and consequently over 99% of the material is left as a light reflecting area. DeAmp metal absorbers can also reduce energy consumptions due to their desirable thermal properties. We offer flexibility in terms of suspension systems and fitting for ventilation and lightning systems. DeAmp metal ceilings are 100% recyclable.

 

 

Perforations

Approximately 0.85% open area

Approximately 1.60% open area

We offer services of tuning our panels to desired problem frequencies, panel sizes can be changed for custom sizes.

 

Recyclability

DeAmp aluminum panels are made from recycled metal and our ceiling panels are 100% recyclable.

Sound Absorption

The absorption coefficient is adjustable to the desired frequency area. The following absorption curves are adjustable by simulations in our proprietary acoustic software specially developed for this technology.

The absorption coeffecient using double layers mounted 100 mm and 125 mm from the noise reflecting surface.

 

The absorption coefficient when the absorbing panel is placed respectively 200, 100 and 40 mm from the noise reflecting surface behind. A multitude of  “panel tunings” can create different absorption curves desirable for troublesome bass frequencies on for example cruise ships or concert halls.
