A product can be tested. A building performs as a complete construction.
Acoustic performance depends on mass, resilience, absorption, airtightness, structural isolation and the control of flanking paths. A strong central layer can still be undermined by a rigid perimeter, an untreated service opening or the wrong construction sequence.
Different noises require different system responses.
The starting point is not “Which acoustic roll?” It is the type of noise, how it enters the structure and where the unwanted sound is experienced.
IMPACT NOISE
Footfall, dropped objects and activity excite the floor structure. The response normally begins with separation, resilience and controlled perimeter isolation.
AIRBORNE NOISE
Speech, television, music and plant noise pass through partitions, linings and ceilings. Mass, absorption, airtightness and decoupling must work together.
STRUCTURE-BORNE NOISE
Vibration can bypass the main acoustic layer through rigid junctions, fixings, services and flanking paths. Continuity at interfaces is critical.
Resilient separation must continue to every edge.
IMPACTODAN belongs within compatible floating-floor constructions, while CONFORDAN routes address suitable timber, laminate or direct-finish floor applications. The finish, screed, loading and required performance determine the route.
IMPACTODAN
Cross-linked polyethylene acoustic membrane used to reduce impact-noise transmission between a structural slab and a separated screed. Laps, perimeter strips and service isolation form part of the system.
CONFORDAN
Acoustic underlay families selected around the intended timber, laminate or compatible direct floor finish. Product variant and compressive behaviour must match the final build-up.
Mass and absorption work best when the construction is decoupled.
DANOFON, ACUSTIDAN and specialist SONODAN routes serve different lining, partition, ceiling and service conditions. The supporting frame, boards, cavity, fixings and junction treatment remain part of the tested system logic.
DANOFON
A high-density bituminous membrane between porous textile layers, used within suitable wall linings, partitions and floating-ceiling constructions to address low, medium and high frequencies.
ACUSTIDAN / ACUSTIDAN PRO
Multilayer acoustic solutions for compatible cavity walls, linings and selected building-service details. The PRO route adds specialist fire-performance and high-performance options where the complete system requires them.
SONODAN PLUS
A project-led lining component for demanding acoustic build-ups, coordinated with framing, absorbent layers, plasterboard mass and anti-resonance detailing.
Added mass changes how lightweight constructions respond.
The M.A.D. family uses high-density bituminous acoustic membranes within compatible layered constructions. These membranes are not decorative linings and should not be judged as standalone “dB products”.
Select mass, format and fire route around the full assembly.
Available families include conventional and self-adhesive M.A.D. membranes, together with project-led M.A.D. PRO routes. The exact grade is coordinated with the plasterboard or panel build-up, support, fixing method, cavity absorber and required fire classification.
Noise often escapes through the elements treated last.
Drainpipes, bends, frame junctions, perimeters and service penetrations can become dominant transmission paths. They require compatible acoustic layers and continuity—not improvised offcuts.
FONODAN BJ
Self-adhesive acoustic treatment for compatible drainage-pipe routes, coordinated with the surrounding enclosure and service detail.
FONODAN 130
Reinforcement strip for bends, junctions and other locally demanding service interfaces where continuity is most difficult.
ACUSTIDAN PRO
Project-selected multilayer treatment for compatible high-performance wall, service and plant-room conditions.
System accessories
Perimeter isolation strips, sealing tapes, GLUEDAN ACUSTIC, fixings and resilient details selected to complete the specified construction.
Six checks before an acoustic product becomes a system.
- 01
IDENTIFY THE NOISEIs the dominant problem airborne sound, impact noise, low-frequency energy, vibration or a combination?
- 02
MAP THE PATHWhich floor, wall, ceiling, service penetration or flanking junction carries the sound into the receiving space?
- 03
DEFINE THE BUILD-UPWhat structure, lining, screed, finish, cavity depth and available installation thickness are present?
- 04
CONTROL THE EDGESAre perimeters, penetrations, frame junctions and services isolated without rigid acoustic bridges?
- 05
VERIFY PERFORMANCEAre the target criteria and tested system data relevant to the complete proposed construction—not only one product?
- 06
CONFIRM THE PROJECT ROUTEHave availability, minimum order, lead time, accessories and current controlled documents been confirmed before commitment?
Available to order—not presented as regular local stock.
Product route, quantity, system accessories, minimum order and lead time are confirmed for each enquiry. Project-specific selection can be coordinated with current manufacturer documentation and technical support.
This page is a system map, not a complete catalogue, acoustic design or compliance statement. Published performance values apply only to the relevant tested construction. The final floor, wall, ceiling or service build-up must be verified against the project criteria, flanking conditions, current controlled documents and applicable acoustic design requirements.
