Acoustic Test Datasheet




The unique DS44 wedge shaped TPE-V perimeter seal requires less energy to open and close due to its flexible elastomeric properties. As the DSA wedge design works so effectively, they are on average 50% more compact overall than competitor’s bulky alternatives – the carrier has a low profile projection of just 5mm and width of 10mm. With the DSA unique fitting system, you can ensure a fast and perfect installation as the seal is positioned and adjusted for optimum performance. Plus the carrier is 100% aluminium (no flimsy, odd coloured plastic inserts used) with a curved edge and smooth surface profile to compliment any door frame.

The DSA TPE-V gasket seal wedge profile is much easier to compress than competitor’s tyre bulb shapes (which is similar to trying to compress a bicycle tyre) and so adds minimal resistance to the opening and closing operation of a door.  The full face of the seal compresses against the closed door face providing high acoustic attenuation as an airtight seal barrier is created.
