It names the separating elements
Walls between two flats, floors between two storeys, stairs, doors and windows within separating elements: the certificate lists what actually separates in your building.
Building physics in the Heinsberg district
Sound insulation certificate for your project in Heinsberg
As soon as flats, terraced houses or consulting rooms sit next to one another, sound insulation belongs to the evidence a building project has to carry. We look at your floor plans, review the build ups you have planned and produce the certificate for your file.

01 The certificate
What a sound insulation certificate is, and when it is needed
The certificate is a document that belongs to your building file. It sets out which elements of your building separate two uses from one another, how those elements are built up, and that the build up delivers the separation your project is required to achieve.
02
It proves the build ups by calculation
For every separating element the planned build up is taken and calculated. Anything that falls short shows up before the building work, not after it.
03
It belongs to the building file
The certificate is prepared alongside the structural calculation, the thermal evidence and the rest of the file. Whether it is submitted in the approval procedure depends on the project and on the procedure.
02 Paths of sound
Three paths on which sound reaches the neighbour
Sound insulation is not a property of a single wall. It arises from how the separating element works together with everything joined to it. That is why a certificate always looks at the whole situation.
01
Airborne sound
Voices, music, a television. Air carries the sound to the wall, the wall is excited and radiates sound again on the other side. The heavier and the better decoupled the element, the less arrives.
02
Impact sound
Footsteps, chairs being moved, an object that falls. Here the element is excited directly. What matters is the floor build up above the slab and how cleanly it stays separated from the walls.
03
Flanking path
The path most easily overlooked in planning. Sound does not travel through the separating wall but past it, along the elements joined to it: through a screed that runs on, through the slab, through the facade.
03 Building elements
Where the certificate looks in your building
These elements decide what arrives on the neighbour side. For each of them the certificate records how it is built up and how it connects to the rest of the structure.
04 How it runs
From the first enquiry to the finished certificate
The route is short and always the same. You send what you have, we clarify the situation, and you receive a document you can work with.
- Step 01
Enquiry and documents
You describe the project and send us floor plans and sections. We tell you whether a certificate is needed and what it will cover.
- Step 02
Clarify the uses
We look at which rooms adjoin each other and what sits above, below and beside what. That decides which elements appear in the certificate.
- Step 03
Settle the build ups
The wall and floor build ups you have planned are reviewed. Where a build up does not carry what it is meant to carry, we propose an alternative.
- Step 04
Produce the certificate
The separating elements are calculated and the result is assembled into a document fit for review, together with the notes that belong on site.
- Step 05
Take changes with you
If a build up is swapped during construction, tell us. We check whether the result is affected by it.
05 Documents
What we need from you for the certificate
The more complete the documents, the sooner the certificate is ready. If something is missing, that is no obstacle. Simply send what you have.
- Floor plans of every storey, to scale where possible
- Sections through the building, with storey heights
- What the adjoining rooms will be used for
- The planned wall, floor and slab build ups, as far as they are known
- Windows and doors that sit within separating elements
- Where pipes and service shafts are planned to run
If you are already working with us on the structural design, most of this is with us already.
06 Services
The certificate comes from the office that also calculates the structure
We prepare the structural design for your project, take on the detailing and produce the building physics evidence. The sound insulation certificate is one of those, and it does not stand on its own.
Structure
Structural calculation, structural design, seismic evidence, steel, timber and solid construction.
Detailing
Construction planning with position drawings, formwork drawings and reinforcement drawings.
Building physics
Thermal protection, moisture protection and sound insulation as the evidence the authorities require.
Because the structure and the building physics are drawn up at the same table, the elements in the sound insulation certificate match the elements that carry the load.

08 Questions
Common questions about the sound insulation certificate
The questions we are asked most often on the telephone. If yours is not here, give us a call.
When do I need a sound insulation certificate at all?
Whenever rooms in a building adjoin one another that belong to different dwellings, different owners or different uses. Apartment buildings, semi detached and terraced houses, extensions and conversions that create new separating elements are the usual cases. Whether the certificate has to be submitted in the procedure depends on the project. Describe yours and we will tell you.
Does a detached single family house need one?
If no other use adjoins inside the house and no neighbouring building is attached, there is as a rule nothing to separate. As soon as a second dwelling, a granny flat or a practice is added, the picture changes.
What is actually in the document?
A description of the building and its uses, the list of separating elements with the build up planned for each, the calculation behind them and the result. Added to that are the notes that matter during construction, for example where the screed has to stay separated.
What is a flanking path?
The route on which sound travels past a separating element instead of through it. A screed that runs on, a slab that carries through or a stiff facade can carry sound around the separating wall. A certificate that looks only at the separating wall and leaves the flanks out does not describe the building.
How long does it take to prepare?
That depends on the size of the building and on how complete your documents are. Tell us your deadline when you enquire. We will say whether it can be met before you place the order.
What does a sound insulation certificate cost?
The effort follows the size of the building and the number of separating elements. We look at your documents and give you the price before any work begins.
A build up was changed on site. What now?
Let us know. A different screed, a different insulating layer or an extra penetration can change the result. Clearing it up during construction is far easier than afterwards.
