Are there any universal internal doors that will provide adequate sound insulation in homes, flats, offices and public buildings? The smoke-proof PORTA SILENCE collection with the acoustic class of Rw = 37dB and the fire resistance class EI 30 will perform excellently in this role.
The models from this collection (available both as rebated and non-rebated variants) have a distinctive design, thanks to which they dampen the noise coming from outside very well.
The sash is filled with as many as 5 layers of PortaSilence® acoustic structure, and the whole is additionally clad with a robust HDF board. In the CPL HQ and Gladstone/Halifax versions, the sides are covered with ABS tape. The price of a complete set consists of a sash and frame.
The coefficient is expressed in decibels and indicates the degree to which the door will protect against noise and outside noise. As a general rule, the higher the value, the better the sound insulation of the door.
