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
Mass - The higher the mass of a door, the better its soundproofing effect. Heavier doors make it easier to reflect incident sound waves for higher sound insulation values.
Door leaves - Since single-layer components have to be very heavy to achieve sufficient sound insulation, multi-layer components are often used instead. In this way, a structure with a comparably low weight can achieve higher sound insulation.
Door frame - The construction of heroal doors ensures that the door frame reflects and absorbs sound waves. heroal acoustic door frames are made of aluminium, which allows them to achieve optimum soundproofing values.
Sealants - Since sound waves pass through the smallest openings, there is no insulation without sealants. Acoustic and rebate sealants make sure that both door sash and door frame are tight, just as the sealants between door and floor.
Installation according to tested installation instructions - Even the best soundproof door will not work without proper installation. Qualified installation by our specialist partners ensures effective sound insulation.
Interesting facts about 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.
