ISOLMANT JUNIOR BOX
Acoustic attenuators for ventilation holes
Acoustic silencer for air vents made of porous expanded polypropylene (P-EPP) and characterised by a high airborne sound insulation and low thermal conductivity. P-EPP sound absorbing proprieties ensure high performances without fibrous and spongy materials that will inevitably deteriorate and then affect the quality of the air. This product ensures a net free area of 100 cm2. Isolmant Junior box is symmetric; therefore, it can be installed in both directions. Grilles covers not included.
This product is compliant with ventilation requirements and it increases the airborne sound insulation of the façade. It is light and it can be easily handled and installed (less than 1 kg). It reduces the thermal bridge and the consequent spots on building envelope. It can be installed in every perimeter wall and then plastered.
