Soundproofing Doors or door soundproofing is the technology or process that is to create a door that is able to stop sound waves from passing through the doors frame and core panel in such a way that the opposite side users experience is that the noise is then silent and undetectable by the human ear.
contrary to popular belief authentic soundproofing doors really are soundproofed and in every aspect are able to reduce large amounts of noise and create a impenetrable barrier against noise. Our NoiseBlock Glass doors are able to do just that.

One of the main reasons behind the general publics misconception that soundproofing doors only help to reduce small amounts of noise is because of the information that is given to them from contractors, consultants and suppliers not being accurate.
They do this in order to low the expectation of the end user as a result of there inability to produce or supply authentic high performance soundproofing doors.
The use of a normal everyday door is to create a barrier for the purposes of privacy, security and of course for the door to look nice.
The general elementals that help us to classify a normal door it the frame, lockset and the core panel. On normal doors these items are very simple in terms of shape, construction and the materials that go in to it.
A normal door most of the time is hollow and looks very similar to the one in the diagram and the photo. There are various different designs and colours but they all share the same construction methodology which ultimately results in sound being able to pass through them like a knife through butter.
As mentioned before our experiences leads us to understand that a typical contractors soundproofing door is basically a plywood door with rockwool thermal insulation inside. The problem here is that thermal insulation is low density and does not block / stop or absorb a lot of sound in terms of dB(A). So this can have a real impact on the results of this type of soundproofing door.
It really only changes the door from being a hollow door to something more similar to a solid door, which again is insignificant in comparison to the real thing.
The plywood that is used is conductive and as you can see from the photo there is a lot of timber supports used that is prefect for conducting noise to flank past the doors areas that have been insulated.
One of the other differences from a normal door and a typical contractors soundproofing door is the use of the perimeter seal and drop seals.
Then we come to the soundproofing door. A real soundproofing door can be made to stop various different levels of noise depending on the requirement and specification.
Sound transmission coefficient classes STC 55dB to STC 75dB is considered to be acceptable in terms of the noise reduction associated with soundproofing door key performance indicators (KPI)
To the right is our NoiseBlock STC 65 door that we introduced into the market in 2015.
Some of the main differences of the soundproofing door is the materials used, the frame, the design of the frame, the seals and the locking system. A soundproofing door needs to lock into the frame and be air tight to ensure that no loss of noise can pass through the gaps which happens with regular doors.
The door core also needs to be specially insulated as with the frame of the door as well.
The doors that we provide offer high levels of sound reduction and can give as much soundproofing mitigation as needed in order to fix your problem.
