Patented acoustic silencer for air vents made of porous expanded polypropylene (P-EPP) and characterised by high airborne sound insulation and low thermal conductivity. Its cylindrical shape allows a simple and quick installation. 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 element can ensure a net free area of 100 cm2 thanks to the pitch of its inside helical geometry. Length 32 cm, diameter 19.4 cm. Isolmant Tubo is symmetric, therefore it can be installed in both directions. Grilles 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 (approx. 165 g). It reduces the thermal bridge and the consequent spots on building envelope.
