StoSilent Direct

The StoSilent Direct system consists of composite mineral fibre boards with a pre-applied, textured surface. The boards are bonded directly to the substrate, and their pre-chamfered joints can be left as is, or filled prior to applying one of the StoSilent textured finishes.

Sto Silent Direct has particularly impressive sound absorbing qualities, and is best suited for continuous ceilings or walls without upstands. Seamless surfaces up to 700 m² can be created without the need for a break in the system, as well as curves down to a radius of 5m.


Sto can advise on which system would be best suited to meet the needs of your project. Please get in touch and we will arrange for a Sto Technical Consultant to contact you and discuss your requirements.
