Supersound-bg.com offers professional soundproofing solutions for HVAC systems, ventilation ducts, and air conditioning installations using premium products from Kaimann Germany and SENOR Spain. These systems are specifically designed to reduce noise, vibrations, and sound transmission generated by ventilation systems, air ducts, fans, and climate control equipment.
Our solutions combine advanced acoustic insulation, vibration isolation, and condensation protection for residential, commercial, industrial, and technical environments.
When noise generated by ventilation systems, air ducts, or HVAC equipment becomes a problem, proper acoustic treatment is essential for improving comfort and reducing structural sound transmission.
Kaimann Saint-Gobain and SENOR specialize in manufacturing high-performance materials for heating, ventilation, and air conditioning systems with optimized acoustic properties and advanced vibration control.
In addition to reducing noise, these materials also help:
Professional HVAC acoustic insulation systems use elastomeric materials with a 100% closed-cell structure designed to prevent moisture penetration and condensation buildup.
These materials provide excellent thermal and acoustic insulation while maintaining flexibility and long-term mechanical stability.
Closed-cell elastomeric insulation is especially important in:
One of the most commonly used acoustic insulation materials for ventilation ducts is Kaiflex DUCT, available in different thicknesses, fire resistance classes, aluminum finishes, and self-adhesive versions.
For professional HVAC acoustic treatment, it is also recommended to install sound attenuators between the noise source and the duct system — most commonly behind the fan unit. This significantly reduces the transmission of noise through ventilation channels and ductwork.
One of the most effective solutions for soundproofing ventilation and cooling systems is the use of KAISOUND 140 and KAISOUND 240 acoustic panels.
These materials provide triple acoustic functionality:
KAISOUND is a highly flexible acoustic insulation material with unique physical properties. Through a specialized manufacturing process, its originally closed-cell components are transformed into an open-porous acoustic structure.
This creates an exceptionally flexible material capable of absorbing problematic frequencies commonly found in building acoustics and HVAC systems.
The combination of:
allows the system to achieve excellent sound reduction and vibration damping performance across a broad frequency range.
SENOR acoustic hangers and vibration dampers are designed to isolate ventilation ducts, pipes, and HVAC systems from structural vibration transfer.
These systems allow safe and efficient mounting of ductwork to concrete slabs and metal support structures while significantly improving vibration absorption.
Professional hybrid hangers such as the SENOR AS+AC/L METAL model are specifically engineered to reduce noise pollution generated by metal air ducts.
The combination of spiral steel elements and elastic polymer materials allows these systems to effectively isolate both low and high frequencies.
Another advanced solution is the SENOR ATB-50 adaptive acoustic clamp, designed for exceptional vibration isolation and induced noise reduction in HVAC and industrial systems.
The latest generation of SENOR vibration dampers features an exclusive design developed for mounting HVAC and climate control equipment onto slabs, frames, and metal support systems.
These anti-vibration solutions help prevent:
Professional installation of acoustic dampers significantly improves overall system performance and acoustic comfort.
