High acoustic rating H3 S T30 steel construction project door

In industrial and construction buildings, increased acoustic insulation is required in some areas of the building, e.g. in passages from production to the offices, in technical areas or function rooms. Our new high acoustic rating H3 S steel construction project doors are particularly suitable for these purposes. They achieve very high acoustic rating values of up to 56 dB and thus minimise noise levels. In addition, the T30 steel construction project doors are fire-retardant and safely separate fire zones from each other. The significantly lower door weight of the H3 S single-leaf doors compared to T90 acoustic-rated doors considerably simplifies transport on the construction site and makes fitting easier.
