History

1949	Friedrich Karl Rogge establishes Odenwald Faserplattenwerk in Amorbach and starts to manufacture wood fibre insulation boards.
1952	Production of the first acoustic ceiling tiles from wood fibres.
1960	Whilst visiting the USA, F.-K. Rogge becomes aware of ceiling tiles made from mineral wool - a material that facilitated the manufacture of fire protection ceilings which would bring about the development of new ceiling systems of crucial meaning. One year later he acquires the European manufacturing licensing rights.
1961	In November 1961, the first mineral wool ceiling tiles leave the Amorbach factory - ceiling tiles with the brand name OWAcoustic^® that has now, through continuous development, become one of the leading names for ceiling systems in Europe.
1977	In 1977 an investment was made in an installation to manufacture mineral wool, substantially increasing production. It produced a "black wool" from basalt - an individual raw material that became an identity feature for OWAcoustic^® tiles for 20 years.
1997	OWAcoustic^® tiles are switched to "white wool" - a Bio-degradable product which fulfils all German and European regulations on health conformity of mineral wools.
