Under-Screed Insulation

We create innovative, high quality, acoustic performance and sustainable under screed insulation for concrete & flooring underlayment

What we believe and what we can do!

Everyone deserves a quieter atmosphere

Carsten Andersen our CEO and Founder
Carsten Andersen, Founder
We believe that everyone deserves good comfort and a quiet environment to live, work and play in. At Scan Underlay, we know that reducement of noise is an important and vital part of everyday life. Therefore, our goal is to develop and produce the most sustainable products which are better at reducing noise in a modern world. We focus on next-generation performance and designs for better human comfort, which is why we develop our products for both better indoor acoustic and environmental needs. Our products significantly exceed standards for noise reduction and the footfall noise transmitted to lower floors. Our revolutionary rubber-textile fiber under-screed sound insulation ensures that sound disappears, heat is well-distributed, and moisture wicks away efficiently. Heavy foot traffic is supported and cushioned, and the experience and performance of this product will not degrade over time, respecting future generations. Read more
