We take care of the perfect backdrop. Because our diverse sound insulation combines high-quality materials with effective function.
All BLH HK baffles are now available with a hygiene conformity certificate according to VDI 6022 (01/2018).
Our BLH sound insulators and splitters optimally attenuate sound in ventilation and air-conditioning systems. Here, the focus of the noise is usually in the frequency range of 250 Hz.
The design and dimensions are variable and are produced according to the customer's specification. The handling from enquiry, calculation, order to delivery is carried out very flexibly. A special design is also carried out for the critical noise range of 250 Hz. The damping material used generally has a glass-silk laminated surface . It is also abrasion-resistant up to 25 m/s and offers effective protection against damage.
The following special designs or agreements are possible on request:
Scenery Structure & Types
Our high-quality baffles are manufactured in a frame made of sendzimir-galvanised sheet steel and absorption material as filling made of mineral wool with laminated glass silk fleece covering, building material class A1 according to DIN 4102 (non-combustible).
base sound insulators
Plinth sound insulator variants
Casing made of galvanised sheet steel 1.5 mm in welded design, including the built-in splitters made of non-combustible absorption material, which are protected against abrasion by flowing air by means of glass fibre fleece.
