Usage
The Renson Silendo 461 AK Ral 9010 acoustic door grille is designed to provide controlled air transfer between rooms while effectively reducing noise transmission through doors. It is ideal for offices, schools, healthcare facilities, and residential spaces requiring ventilation and noise control.
Advantages
- Reduces sound transmission through door openings for increased privacy and comfort.
- Ensures efficient airflow between interior spaces without compromising acoustic insulation.
- Discreet design with a white (RAL 9010) finish that integrates seamlessly into any door or partition.
- Constructed from durable aluminium profiles for longevity and low maintenance.
- Simple installation using standard tools and hardware; minimal impact on structural integrity of the door.
Specifications
- The grille features robust extruded aluminium construction with internal micro-acoustic material to absorb sound energy and reduce airborne noise transfer[2][5].
- The product adheres to relevant European standards for acoustic performance; typically tested according to ISO140-3 protocols[2][8].
- The effective free ventilation area is approximately 29% of the total plate area. Common attenuation values range from around 30 dB up, depending on installation specifics[5].
- A white powder-coated (RAL 9010) finish offers a clean appearance suitable for most contemporary interiors. Modular design fits various door thicknesses as required by project needs. Dimensions should be checked per application prior to installation[5].
How it works
This acoustic grille channels air through an array of openings lined with sound-absorbing material. As air passes through the grille installed in a door or partition, unwanted noise energy is absorbed internally, enabling fresh air flow without direct line-of-sight sound paths between adjacent rooms[4][5][6]. The result is improved indoor comfort with maintained privacy and compliance to modern building regulations on both ventilation and acoustics.
