TIMBER DOORS General Purpose Noise Control Fire-Resisting

Transcription

1 General Purpose Noise Control Fire-Resisting NCO developed a range of timber doors for a variety of applications. These doors are being installed to effectively control noise and fire-resisting in conference rooms, broadcasting studios, theatres and music practice rooms. Acoustic doors, tested in the accredited laboratory, equipped with compression seals around the periphery of the doors. Fire doors are tested to BS476- Part 22:1987 with fire rating up to two hours for stability and integrity. An intumescent strip is used for fire rating doors. The following figures present the results for various doors: ACOUSTIC DOOR PERFORMANCE Model Weighted Apparent SRI R w (ISO-1-3) Sound Transmission Loss (STC), db (ASTM-E90) Noise Insulation Class (NIC), db (ASTM-E336) 37dB-TA dB-TA db / 41dB-TA / dB-TA dB-TA dB-TA dB-TA dB-TA dB-TA 49 FIRE DOOR PERFORMANCE Fire Code: (To BS 476: Part 22:1987) Model Stability Integrity Insulation F minutes minutes - F1/F1A* 1 minutes 1 minutes minutes* GENERAL PURPOSE DOOR (Non-Acoustic, Non-Fire rated) Model Core/ Thickness FSTC (Estimated) GP44-H Hollow/ 44mm < db GP-H Hollow/ mm < db GP44-S Solid/ 44mm 25 db GP-S Solid/ mm 25 db Model:37dB-TAF (STC 37) Model 37dB: STC data Weighted sound reduction index Rw is 37dB W eighted sound reduction index Rw is 39dB Model:39*dB-TA (STC 37)
