Sound Insulating Door


Acoustic doors are specialist assemblies offering a higher level of sound insulation, 44 dB SRI Rw (maximum) where required, e.g. in top-level offices, auditoriums and plant rooms. Certain doors in this range can also provide 30 or 60 minutes fire resistance, and the same high quality of appearance and performance as all Shadbolt doors.
