Tektalan A2
Tektalan A2
Description
Multi-layer wood wool acoustic panel with a stone wool core (Heraklith, Knauf Insulation Austria). The standard solution for underground car parks, basements and plant rooms: thermal insulation, fire protection and sound absorption in a single directly mounted panel. The Basic, Basic F, Protect and SmartTec versions differ in fixing and surface; per the datasheet their absorption values are identical for a given thickness and are combined here. SmartTec [1.0] and Silent carry their own datasheet values, and SD TwinTec is the version cast into concrete.
