Armacell has released ArmaComfort AB and ArmaComfort AB Alu, a new range of acoustic foams designed specifically for noise control in plumbing applications.
The products are easy-to-install, whilst the multi-layer construction, consisting of a 2mm thick foil faced acoustic EPDM-EVA barrier with 4kg/m2 weight and a 10mm polyurethane foam layer for decoupling, makes it far more effective compared to traditional products, and at much reduced thicknesses.
The ArmaComfort material is highly flexible and easy to fit, allowing it to be installed in tight spaces without the need for special tools or accessories. The handy roll format and self-adhesive backing allows fast and simple installation.
Noise created by wastewater pipes and internal rainwater systems are one of the most frequent sources of disturbance in living and working environments. In un-insulated applications this noise is transferred via pipes to wall and ceiling elements, and from there to internal rooms.
ArmaComfort AB and ArmaComfort AB Alu has been specifically developed by Armacell to provide a highly effective method of attenuating these sound waves in apartment and residential buildings, offices, hotels, hospitals, schools and private homes.
Independent tests by CSTB (Centre Scientifique et Technique du Bâtiment) confirmed that ArmaComfort AB reduces the airborne sound pressure level of a Geberit roof drainage system by 16 dB (A) at 2 l/s water flow.
Similar ArmaComfort AB tests on a PVC pipe, where the vibrations caused by flowing water are stronger because of the lighter weight PVC, achieved a noise reduction of 12 dB (A). The human ear perceives a reduction of 10 dB (A) as halving the volume.
ArmaComfort products achieve a weighted sound reduction index (Rw) up to 28 dB when pipe and elbows are insulated.
The products display very good fire behaviour; with B-s1,d0 ArmaComfort AB Alu achieving the best fire class for organic products in the European SBI test.
Aluminium foil pressure bonded to the decoupling foam complements metal-clad installations in areas where the pipes are visible and as a closed-cell insulation construction, ArmaComfort AB prevents condensation forming on pipes.
Effective sound protection can increase both the comfort and the value of the property. Specifiers and contractors that choose ArmaComfort AB products are better able to address our increased awareness of noise pollution in buildings.
