Noise insulation of wall and ceilings

Here, you will learn how to insulate walls and ceilings - here, you will find solutions to the following two questions

1. I am very loud and I want to insulate other rooms from the noise in my room

2. My neighbour is very loud / the adjoining room is very loud and I want to insulate my room against the noise coming from outside.

Here, you will learn how you can effectively insulate the noise

1st option – You mount only foams

You must attach the sheets in the room in which the noise is created. Thus if you want to insulate the noise that comes from your neighbours, your neighbour must mount the sheets in his room on the corresponding adjacent wall. If you want to insulate the noise you generate for the neighbours, you must mount the sheets in your room. Ideally, you should use the thickest possible rebond foam sheets in this case – the thicker the sheets, the better the insulation. You can maximise the insulating effect if you adhere our 3-layer construction consisting of foam sheet – bitumen sheet – foam sheet. You will find more detailed information on this construction in our “Noise Insulation” guide. However, you cannot attach anything to a foam wall, no pictures or anything similar, and you cannot wallpaper  or paint the foam. If you want to preserve the look and functionality, the 2nd option is the more appropriate one.


2nd option – You mount foams and put in a new wall
You need plasterboards (or similar firm sheets). You adhere rebond foams in turn to these sheets. The thicker, the better the insulating effect. You must then mount this construction in a floating manner in front of the original wall  - you will need the assistance of a drywall builder here. The new wall should be decoupled from the other walls and the floor so that vibrations cannot be transmitted (e.g.: via rubber or silicone joints). 1 – 2 cm of space should be left between the original wall and the foam to reinforce the insulating effect. The foam is thus between the two walls at some distance from the original wall. You thus have a fully functioning wall and optimal insulation between the walls or to the neighbouring apartment or adjacent room.


3rd option – When the noise comes from the room above you
If the neighbour above you is too loud or if footfall noises are very loud, you must mount the same construction to the ceiling as described above. You must suspend the ceiling and lay or adhere the foam to the new ceiling. There should be 1-2 cm of space again between the original ceiling and the foam. In addition, the neighbour above you should lay a suitable footfall sound insulation under his flooring if he is reasonable here.


4th option - When the noise comes from below

A new ceiling must be mounted and suspended in the room below you. Our foam (rebond foam) must then be adhered in turn to the original ceiling. There is no other solution here. For more information, you will need the assistance of architects and drywall builders on-site.

You can order the appropriate foam and the bituminous foil as described above directly from us online. The thicker you choose these, the better the insulation is. However, you will then need more adhesive accordingly so that the foam sheets adhere well to the wall/ceiling. You will need the assistance of a drywall builder or an architect to put in a new wall or to suspend the ceiling.
