Sound Insulation for Walls

Insulating partition between homes
In order to acoustically separate two rooms, homes for instance, the partition wall must always be insulated. The correct way of insulation is to place a construction that functions as a barrier between the sound source and the receiver, i.e. the side that experiences the nuisance. Such a construction can consist of a floating wall or a floating ceiling. This construction reduces the radiation of sound, which in turn reduces the nuisance resulting from airborne noise.

By using Merfoflex Intermediate Rails you can create a decoupled wall or ceiling in the room where you experience the nuisance. A product video, manual and explanation can be found on the  productpage.

Insulating system wall or plaster wall
Light partitions, made of plasterboard for example, are optimally insulated by doubling their mass (weight). You can carry out the insulation process by using Isomat KE14. Equip the side of the Isomat Isomat KE that contains jute with Stauf glue and mount it to the wall, avoiding entrapment of air bubbles. Screw or nail the Isomat plate onto the wall at the corners (Isomat is hard and does not press in, so screwing is no problem at all). Then, finish the Isomat with a plaster or wood board. This way of insulating is very effective with this type of wall and is relatively inexpensive and easy to carry out. (This is the same insulation method used for wooden floors). Repeat this principle on both sides of the wall to achieve an optimal result! Make sure that the wall is properly connected to the architectural ceiling, especially in rooms with a system ceiling.


Building acoustic walls
If you are going to divide a room into two rooms, it is desirable to ensure privacy. Equip a wooden latticework with Agglomer strips all around and fill the space between the trusses with Akoesti wool PE60 (this type of polyester wool is 60 mm thick). Close the wall by mounting Merfoplex on both sides instead of plasterboard.

Think about the doors as well. They should be insulated at least as much as the walls, so that they do not form a sound leak! You can find complete sound insulating door sets with excellent insulation values in our webshop.

Flanking sound and end result
At first glance, most of the nuisance seems to come through the partition wall, but noise can also enter through other construction parts such as walls, ceiling or floor, which are connected to the partition wall. This flanking sound largely determines the end result of the insulation materials used. It is therefore possible that you have to provide several wall or ceiling parts with Merfoflex.
