The slimmest damper for 45/48 mm profiles
Model FTD-MINI-47/TD
This revolutionary acoustic wall lining hanger, manufactured with the most advanced technology in polymeric materials by the renowned German manufacturer KRAIBURG, has been designed with exceptional meticulousness to provide an experience of peace and comfort in spaces where intense activity generates disturbing impact noise and vibrations. In addition to its innovative design, the acoustic hanger incorporates a technological breakthrough in performance through its new patented design. Specifically engineered to operate effectively in spaces with limited room.
Its functionality stands out for its ability to create acoustic wall linings with minimal loss of space, achieving a uniform and perfectly leveled finish—essential for ensuring optimal sound quality and proper aesthetics within the available space.
This acoustic isolator features an integrated CLIP-STOP system capable of providing a fast and reliable grip on TC-47 metal framing, keeping it firmly and consistently in place, thus ensuring a solid and dependable integration in any building structure.
Situations where implementing this dampening technology is particularly relevant include venues where noise levels exceed 80 dBA during daytime hours. Examples of such spaces are: Dwellings, coffee shops, ice cream parlors, restaurants, and supermarkets. In these environments, daily interactions and ambient noise can cause discomfort not only to customers enjoying various activities and events, but also to residents near the premises. This context highlights the urgent need for effective noise control solutions, making this acoustic hanger a superior choice for those seeking to mitigate unwanted noise in compact spaces while maximizing comfort in sound-saturated environments.
It is important to emphasize that this product is not the most suitable option if the original wall has irregularities or lacks proper leveling. In such circumstances, we recommend considering the FTD-NIVEL-47/TD range. This type of hanger offers the advantage of leveling and correcting various irregularities in the base wall, ensuring that the acoustic wall lining remains perfectly aligned and flat. This innovation proves particularly valuable in construction projects where available space and the topographical features of the substrate present significant challenges, complicating visually pleasing and acoustically efficient masonry work.

Test Report Nº: 110909-620 A
Purpose: Airborne Soundproofing Test
Standards: UNE-EN ISO 10140-1:2022 and 10140-2:2022
Laboratory: TECNALIA (Vitoria, SPAIN)
Date: 15 April 2024
Sample: DANOSA+SENOR DIRECT ACOUSTIC WALL LINING
Standardised Base Wall: 15 cm concrete block + plasterboards on both sides
Standardised Base Thickness and Weight: 17.5 cm and 300 kg/m²
Total Wall Lining Thickness: 9 cm
Sample Description: Direct wall lining system comprising: SE-FTD MINI 47 dampers (SENOR) + SE-BEC-8×80 acoustic strip (SENOR) + TC-45/48 profiles (PLACO) + SE-MONT-BICAPA-40 decoupling strip (SENOR) + DANOFON multilayer component (DANOSA) + 12.5 mm Plasterboard (PLACO) + 4 mm M.A.D.4 acoustic membrane (DANOSA) + 12.5 mm Plasterboard (PLACO).
Result: An improvement of 12 dB in airborne sound compared to the base wall, which has a rating of 47 dB, resulting in a total soundproofing of 59 dB.
