By incorporating Svenska Aerogel's material Quartzene® into low-density cellular concrete, Isoltech has achieved outstanding thermal insulation performance - without the cracking or fragility common in conventional solutions.

GÄVLE, Sweden, Sept. 5, 2025 /PRNewswire/ -- In late 2024, Svenska Aerogel provided samples of Quartzene® to Isoltech, a leading Italian expert in cellular concrete technology. The material was tested as part of Isoltech's research and development initiative targeting lightweight, thermally insulating concrete. The results confirmed that Quartzene® significantly improved the concrete's thermal insulation properties, achieving a thermal conductivity as low as 0.031 W/m•K. This improvement was achieved without compromising structural integrity, addressing a key challenge in conventional lightweight concrete solutions.

The breakthrough was made possible by a novel integration of Quartzene® into the cellular concrete, using the expertise know-how and custom-engineered machinery from Isoltech.

This solution enables:

• Higher insulation with less material
• Recyclability increases when only concrete is used
• Reduce weight and CO₂ footprint
• A ready-to-scale solution

Quartzene® enhanced cellular concrete enables lighter structures, lower emissions, better recyclability, and superior building insulation performance – delivering measurable gains in efficiency and sustainability.
