Technical data

Overview of the technical data of the OWAlifetime collection


The size indications for the different systems always relate to the dimensions of the module. The precise size of the individual tiles is coordinated precisely with the systems by the factory.

Fire behavior

OWAcoustic premium: CAN/ULC-S102 class 1 (ASTM E84) | class A (ASTM E 1264)


OWAcoustic premium: Standard 5/8″ nom. or 3/4″ nom.


OWAcoustic premium: approx. 160 – 450 kg/m³

OWAcoustic smart: ca. 280 – 350 kg/m³

Basis weights

OWAcoustic premium:
Thickness 5/8″ nom.: approx. 3.3 – 4.8 kg/m²
Thickness 3/4″ nom.: approx. 3.3 – 6.8 kg/m²


Careful installation and appropriate working conditions are a prerequisite for a perfectly installed ceiling.


Only use construction parts from the OWAconstruct® range– the right profiles and individual elements are available for every installation.

Before laying OWA ceilings, please ensure:

• Rooms are dry
• Plastering, screed and installation work as well as wet operations are complete
• Windows and doors are already installed and glazed
• The heating system is connected and can be operated where necessary


The substructure consists of galvanised sheet steel. Visible sides are white coated as standard. Other colours available on request. Weight (depending on system): approx. 1.5 to 3.0 kg/m²

Coefficient of thermal conductivity

0.055 W/mK

Light reflection

approx. 78 – 91% (depending on design)

Relative humidity

OWAcoustic premium: to 95% RH, peak

Sound protection

Against transmission of sound over the ceiling cavity:
sound reduction of 24 dB to 41 dB.

To reduce noise and regulate reverberation time:
average sound absorption of 15% to 100%.

Transport & storage

Do not drop individual packages and do not set them down on their corner or edge. Store in a dry place and on an even surface, do not place on damp ground. The tiles are always packed face to face in the cartons. Where possible, uncover the tiles by cutting through the packaging. Always take two tiles out of the box or packet together, face to face. Always grasp the tiles with both hands. Multilingual notes on the storage and treatment of OWAcoustic® tiles are enclosed within every package.

Follow-up treatment

Colour-coated OWAcoustic tiles can be repainted at any time after previous insulation coating. Please refer to point 3.9 in the installation instructions No. 9801 or 9801 e.
