OWAtecta Metal Ceilings
Product Details
OWAtecta makes use of tiny holes in the ceiling panels to improve sound absorbtion. This concept is embodied in OWAtecta Perfora - the perforated metal tile that looks almost plain.
The Appearance
Because the perforations are so small, Perfora tiles give the impression of having a plain surface.
High Light Reflection
Although the panel has a perforated surface, the light reflection is similar to that of a plain unperforated ceiling panel.
The reason is that only 0.64% of the surface area is perforated leaving 99% of the surface light reflecting.
The Acoustic Principle
When sound passes through millions of tiny holes (diameter < 0.5mm) friction is created between the air and the inside of the holes, hence a reduction of sound energy. This results in an optimum sound absorbtion.
Measurements of reverberation time, using two different types of OWAtecta ceilings proves this fact.
