Tonga® dB 43 A

Tonga® dB 43 A ceilings offer a perfect balance between sound absorption and sound insulation. Ideal in places where acoustic is essential.

• Room to room sound insulation: Dnfw = 43 dB
• Sound absorption: αw = 0.95
• Rw = 22 dB, according to ISO 10140-2

Implementation and maintenance

Installation
• You are advised to ensure that air can circulate between the rooms and the plenum to balance the temperature and pressures on each side of the ceiling.
• Tiles can be cut with a craft knife without generating any noise or dust.
• The direction in which the panels should be installed is indicated on the back of the panels.
• Contact us if any mineral wool is to be laid in the plenum.

Cleanability

The ceiling surface does not retain dust, which makes the panels easier to clean. The ceiling can be cleaned using a light brush or a vacuum cleaner. This type of cleaning will help extend the service life of the ceilings.

Certifications

Material Health
EUCEB Eurocoustic panels are manufactured using mineral wool certified by the European Certification Board for mineral wool products (EUCEB), which independently confirms that mineral wool is produced in conformity with the Note Q of European Regulation (EC) No 1272/2008 and therefore classification as a carcinogen does not apply.
REACH Eurocoustic products comply with the REACH regulation of the European Chemicals Agency and therefore do not contain any Substances of Very High Concern (SVHC) with potential negative impacts on human health or the environment above 100ppm.
Circularity
Minimum recycled content 25%
Recyclability Fully recyclable

Ce Markings

Eurocoustic ceilings are CE marked according to the European harmonized standard EN13964:2014. CE marked construction products are covered by a Declaration of Performance (DOP) which enables customers and users to easily compare performance of products available on the European market.
