Marking | Technical Feature for Ceiling

|  Reaction to Fire
|  Asbestos Content
|  Release of Formaldehyde
|  Durability / Class of Exposure
|  Shatter Properties
|  Flexural Tensile Strength (FTS) for Safety
|  Sound Absorption & Sound attenuation
|  Thermal Conductivity
Permitted calculation methods for determining thermal performance are ISO 6946 and ISO 10211-1, from data from EN 12664 or EN 12667 tests, or reference design data from EN 12524.

Thermal conductivity is not a ‘mandatory’ requirement and therefore will not be included on Armstrong CE mark labels, however, information on the thermal conductivity can be found in Armstrong literature.
