Over-insulating
Too much sound insulation is a waste of money and just as disturbing as too little insulation, because suddenly the sounds from the neighbours in the next flat or the noise from the technical installations (water, ventilation), seem unbearable. There is no sound from outside to cover them up. Moreover, it gives the person a feeling of isolation indoors – cars are visible, but cannot be heard.
Optimising the glazing
A high mass per unit area and different pane thicknesses have a positive effect on sound insulation. The use of heavy gases between the panes as well as special foils or cast resin significantly improve the sound insulating properties of the glazing.
Joint design and assembly
The nature of the joint and the installation of the window in the building are among the most important factors for sound protection. Heavy joint insulating materials, such as precompressed, impregnated sealing tape in the gaps and air-tight termination indoors, prevent joint noise.
Frame and sash design
At least two continuous sealing levels and the proper assembly of the frame and sash ensure maximum air-tightness and sound insulation. Large steel reinforcements with the strongest possible walls enhance this effect.
Superlative sound insulation
Passing lorries. Thundering jet planes. Blaring music. Blasting pneumatic hammers. One thing is for sure – noise is not only bothersome, it can also harm your health. Because the fact is: those who suffer sleep disorders caused by noise have a significantly higher risk of allergies, heart disease, high blood pressure and migraines. We are subjected to an unbelievable number of different sources of noise daily – often around the clock.
We at SIP have done a lot of thinking about sound protection. Since sound protection depends on the perfect interplay between several components, it is important to view the entire component in context to the building. And that means: the window frames, gap seals, the connection to the building and the glazing must all meet the sound protection requirements in order to attain the appropriate values. With pvc windows from SIP, you have the guarantee that noise stays outside when you are inside, because with the appropriate glazing, PVC windows from SIP are classified in sound protection class 5. Your benefit: peace and quiet, and even more peace and quiet.
What is noise?
To calculate the sound reduction index of building elements, it is important to know the relevant levels for inside and outside. The sound reduction index Rw is the most important measure for sound insulation. Like sound, it is specified in dB (decibels). The effective standard is DIN 4109 “Sound insulation in buildings”, also frequently used is the VDI Guideline 2719 “Sound insulation of windows and their auxiliary equipment”. To calculate the sound reduction index of building elements, it is necessary to know the outside noise level and the use of the room inside.
To increase the sound insulation of windows, the following measures are practicable:
/// Optimising the glazing
/// Joint design / assembly
/// Frame and sash design
