Noise insulation of doors

The noise insulation of a door is determined by 2 matters:
- the gap sealing
- the insulation value of the door

Gap closing

It does not matter how thick and heavy your door is; if the gap closing is not good then the noise will simply pass through simply into the room. So by sealing the gaps well with window tape or rubbers the noise insulation can be dramatically improved. The closing at the threshold is often a weak join, so a rubber flap could be a solution.

Attention: The sealing of gaps of inner doors has the disadvantage that the air in the rooms will circulate less. So, you should ensure that enough fresh air comes into the rooms in other ways .

Insulation value of the door

When the gap is well sealed the isolation value of the door can be improved (further) by increasing the mass of the door. You can not achieve good results with light doors.

That’s why you can place a new, (very much) heavier door. You can also increase the mass of the existing door By making it heavier with Isomat TS. Isomat TS must be applied all over the door with as few gaps as possible.

In choosing the Isomat TS type; the heavier, the better, applies. Pay attention here that the door and the hinges can support the extra mass.
