√ Reduce vibrations
and noise with sound insulation and dampening
√ Reduce noise and vibrations with sound insulation and dampening Reduce vibrations and noise - Protect your system and its surroundings HVAC systems involve many moving and rotating components that can create vibrations and noise. To avoid performance issues or damage and prevent unwanted noise, effective dampening is crucial.
x Avoid damage and prevent noise caused by vibrations Insufficient vibration dampening can lead to unwanted noise and performance issues, making good vibration dampening crucial. Choose dense, long-lasting materials such as rubber and PUR foam, as these have excellent vibration insulation properties.
Reduce disturbances with effective sound and vibration insulation & dampening
Minimize unwanted noise using sound insulation solutions As authorities and organizations become increasingly aware of noise, further regulations are implemented. Keep one step ahead of these expectations, and choose solutions with sound-dampening properties suitable for the noise of HVAC systems.
√ Reduce noise and vibrations with sound insulation and dampening
Say goodbye to annoying vibration and noise... We make it easy to select solutions that meet the strict noise regulations. As disturbing noise and vibrations can significantly impact the indoor environment, we have developed DAFA Sound, a complete material system that effectively deals with both concerns.
Our solutions in dense PUR and rubber materials even out vibrations, so they will not turn into noise or interfere with the performance of the system. They also efficiently dampen noise, so they will not affect the surroundings of your system.

Structural sound damping
By reducing the reflection of airborne noise, surroundings become more comfortable due to lower noise levels. Products with high aural comfort are sought after in the industry.
Growing demands from authorities and organizations regarding noise levels are often the driving force for sound insulation of products or manufacturing systems.
Structural sound damping is about avoiding the propagation of plate vibrations. It is particularly applicable to structures, enclosures, and cabinets.
Solutions are adapted and designed based on the DAFA Sound range for the product and the materials they are to match. This achieves results that make our customers’ finished products even more competitive.
DAFA Sound contains products which, together with DAFA’s other skills, ensure sound effective solutions for insulating the noise source or shielding from the outside world. DAFA Sound thus contributes to ensuring that noise and vibrations are less disturbing. o users.
The DAFA Sound range includes special products designed to absorb and optimize acoustics. It requires solutions designed individually with regard to raw materials, composite materials, surfaces, colors, and shapes.
√ Prevent leaks by using
universal cable seals and pipe collars
√ Prevent leaks by using universal cable seals and pipe collars Prevent leaks around cables and pipes - Be aware of tight sealing in complicated sections It can be quite challenging to find solutions that ensure an airtight seal around cables and pipes. Insufficient sealing can lead to air leaks, jeopardizing the performance and energy efficiency of your system.
Cable seals – makes complex seals easy If you use universal and flexible cable seals, it will be easy and simple to create an airtight seal around cables.
