In addition to burglary protection , thermal insulation and design , sound insulation also plays an important role in the choice of a front door. heroal aluminium front doors are available up to sound insulation class 3, which means they can reduce the sound level by up to 39 decibels. A conventional room door, on the other hand, achieves sound insulation of around 15 to 25 decibels. There are several factors that make a good sound insulation door – such as the mass, the tightness and the installation. Every element has to be properly integrated to provide effective sound insulation.
Sound insulation for doors is often indicated with the sound reduction index (Rw) and test value (Rw,P). The sound reduction index (Rw) provides a guide to the measured sound insulation when the door is installed. The test value (Rw,P), on the other hand, represents the sound insulation under laboratory conditions. Since the test value should be 5 dB higher than the desired value, the following formula is used: Rw = Rw,P - 5 dB.
Depending on the requirements, heroal acoustic doors can be upgraded as high as sound insulation class 3, which allows them to meet the highest sound insulation demands. Try them out for yourself.
