The new Wavin AS + system has been refined to meet the changing needs of today's designers and installers. The 30-year manufacturing experience has been supplemented by thousands of hours spent in noise measurement laboratories to create the optimal mix of next-generation material and investment in a new coupling gasket that eliminates the need for coupling lubricants. The new Wavin AS + marks incredible advances in noise reduction and installation ease. And it happened by accident. Wavin AS + is a combination of a unique high-density material, high-performance system components and versatility for both small and large buildings. With a sculptural nipple and a lubricant-free gasket, the Wavin AS + is not only super quiet, but also super easy and quick to install, the most advanced building drainage system on the market.
