Light reflection expressed in % is measured in accordance with ASTM E1477.
Rockfon ceiling tiles are dimensionally stable even at humidity levels of up to 100% relative humidity and can be installed at all temperatures ranging from 32 °F to 104 °F. They can be installed during the very early stage of the build (when windows are not fully sealed). Their lightweight yet stable non-hygroscopic character minimizes the final weight of the fully-installed ceiling.
