Diathonite Screed

Diathonite Screed

Cork limits heat loss, by improving thermal comfort when used in a product that serves as a screed. Thanks to its natural resilience it
guarantees acoustic insulation and fire protection, even when applied with minimal thicknesses; this property, combined with its inherent lightness, creates a performant product unmatched by any other solution available on the market.

In Diathonite Screed, cork plays an essential role in the performance of thermal and acoustic insulation. Its unique properties – lightness, mechanical strength and porosity are what underpin the excellence of Diathonite Screed.

The Diathonite Screed formulation combines all that nature has to offer in order to produce a material with thermal and acoustic insulation properties coupled with minimum thicknesses and a low environmental impact.
