Acoustics in private homes
Why are perforated gypsum boards necessary in homes?
It is more the rule than the exception that ceilings in kitchens, family rooms and living rooms are high, which provides more light and air and comfort for the eye and mind. The higher the ceiling, the longer it takes for sound to decay in a room. Tiled and wooden floors and brick or aerated concrete walls are all hard surfaces that prolong sound. Acoustics is all about how long it takes for sound to lose its energy.
Poor acoustics means that:
- Conversations are tiring.
- Children’s games are experienced as sheer noise.
- Audio equipment does not work as it should because of persistent reverberation.
The solution is to install sound-absorbent materials, such as perforated plasterboard panels, in rooms by incorporating them into walls and ceilings.
How many panels should be used?
There are no legal demands or formal recommendations when it comes to acoustics in private homes.
To gain the best possible damp of the reverb, we recommend that the whole ceiling surface is covered with perforated gypsum panels.
Where rooms with very high ceilings (higher than wide) are concerned, there should be acoustic regulating materials on walls.
What to choose
Knauf Danoline recommends Designpanel or Tectopanel
Tectopanel is available in size 60 x 60 cm. The panels are supplied with bevelled edges on all four sides.
The bevelled edges have the advantage of making edge filling unnecessary. Finishing treatment at the building site therefore only involves spot filling screw holes and subsequent painting.
Designpanel is available in two sizes – 90 x 270 cm and 120 x 240 cm.
Panels are supplied as standard with recessed long edges and straight short edges. But they can also be ordered with recessed edges on all four sides, which can be recommended in general.
How to integrate
Integration in the main structure
The perforated panels can be integrated into the main ceiling structure, as illustrated here:
1: Truss | 2: Vapour barrier | 3: Battens | 4: Perforated gypsum boards
Adding the acoustic material as built-on
1: Slab | 2: Battens | 3: Mineral wool (recommended min. 50 mm) | 4: Perforated gypsum boards
