CEILING SOUNDPROOFING

Poor soundproofing of ceiling against the upstairs neighbors is the most common problem encountered by our customers. Upstairs tramping, falling objects, moving furniture and other impact noises are the top irritants. And this is not surprising: the improper construction of the floor in the upstairs neighbors’ apartment may result in exceeding the standard values for as much as 20 dB! Let us analyze the options of soundproofing the ceiling prior to mounting of the stretch ceiling or the suspended drywall ceiling.
(4-5 cm thick)
The basic option of the ceiling soundproofing is the frameless system with sound insulation layer placed either under the suspended ceiling or under the Armstrong type paneled ceiling. The efficiency is achieved due to the increased sound absorption in the room – the noise transmitted from the neighbors fades out more quickly because the sound insulation layer on the ceiling excludes the multiple repetitive reflections of sound waves (thus preventing them from increasing). The MaxForte-EcoAcoustic slabs, 3 or 5 cm thick ECOslabs or MaxForte-SoundPRO. The entire area of the ceiling should be covered with sound insulation. The materials should be attached to the ceiling with the acoustic foam MaxFORTE-SoundFLEX. Sound insulation can be easily and quickly mounted by the regular construction gang working at the site. It is an ideal solution for new buildings and offices (including call centers).
(4-5 cm thick)
This thinnest option of ceiling soundproofing comprises the drywall and the profiles. It is an ideal solution for the apartments with low ceilings where every centimeter counts. This structure is based on the 60/27 mm KNAUF profile providing a smooth ceiling surface immediately. The rolls of MaxForte-SoundPRO – a state-of-the-art composite material which is only 12 mm in thickness – are applied for sound insulation. This material should be attached to the ceiling with ordinary expansion anchors. At the points where the frame is attached to the concrete, the SoundPRO is compressed and due to this acts as a damper reducing the vibration. At the rest area of the ceiling, the material absorbs the sound waves due to its fibrous structure. Thanks to the enhanced flexibility of SoundPRO, it can be used as sound insulation even for complex-shaped ceilings (with pipes, wiring, or height difference). 3-4 times reduction of noise from the upstairs (down to 12-14 dB).
(4-5 cm thick)
This is a second thin option of ceiling soundproofing. In this option, the impact noise is isolated by the VibroStop Standart vibration insulating hangers, and the sound is absorbed by the 80 kg/m³ MaxForte-ECOslabs (thin slabs of 3 cm in thickness). This structure is based on the 60/27 mm KNAUF profile providing a smooth ceiling surface. After the ceiling is mounted, it is ready for finishing; no additional levelling should be required. The above structure is designed for complete isolation against the domestic noises – like voices, TV, footsteps and trampling – in the apartment buildings. Noise reduction down to 14 dB.
(7-8 cm thick)
The most proven sound insulation option used in apartments. The vibration isolation is ensured by special MaxForte PRO series vibration insulating hangers. The sound is absorbed by the MaxForte-ECOslab or EcoAcoustic sound-absorbing slabs. The sound insulation of the ceiling meets the standard KNAUF designs, so it can be mounted by any workers engaged in repair of apartments. Both airborne and impact noises will be removed with the same efficiency (with noise reduction down to 20 dB)!
(9-10 cm thick)
This option provides the maximum sound insulation of the ceiling in the most difficult cases including home theaters, stereo systems, or strong impact noises from the upstairs. As the first layer, the MaxForte-SoundPRO in rolls should be attached to the ceiling; then, the KNAUF profiles should be attached via the vibration insulating hangers; next, the sound-absorbing 60 kg/m³ MaxForte-ECOslabs should be placed between the profiles. The combined use of two sound-absorbing materials - the MaxForte SoundPRO and the 60 kg/m³ ECOslab - allows to get the highest possible sound absorption at the entire range of the frequencies including the low frequencies (the impact noises like tramping or falling objects). After the mounting, we get a completely soundproof ceiling with an increase in sound insulation of 22-25 dB!
