Energy efficiency made simple
HeiQ Xpectra is a transparent coating designed to reflect heat and thus improves the energy efficiency of buildings without requiring costly construction work. The coating reflects up to 74% of heat radiation and can improve the heat transfer coefficient (U-value) of walls by up to 25%, which significantly reduces heating and cooling requirements. Its simple application as a spray coating makes it particularly easy to retrofit in existing buildings and opens up great scaling possibilities. The certified very low VOC emissions and local production contribute to better indoor air quality and lower transport emissions.
Global testing and partnerships
The technology has been launched for concrete walls at the BAU tradeshow 2025. Ongoing collaborations with HeiQ Xpectra partners have been crucial to its success: LEONHARD KURZ contributed expertise in advanced coating formulations, and CAE, the Center for Applied Energy Research in Würzburg, Germany, provided performance testing to validate energy efficiency and durability. First results from testing in Thailand indicate significant potential for improving thermal comfort in tropical climates, supporting energy savings for space cooling.
From vision to impact
The award jury recognized HeiQ Xpectra for its transformative potential in climate action, citing its ability to reduce CO₂ emissions, conserve energy, and support resource efficiency. The product’s development was driven by a clear narrative: turning the global retrofit challenge into a practical climate solution. By replacing traditional renovation with a high-performance coating, HeiQ empowers building owners to act swiftly and sustainably.
This achievement reflects the dedication of the HeiQ team and its partners. As noted by Dr. Oliver Zech, CEO of HeiQ RAS AG: “The German Sustainability award is a success example for HeiQ as deep tech material innovator andto our shared commitment to innovation and sustainability. The award strengthens our position in the market and opens new opportunities for collaborative commercialization.”
Scaling for the future
HeiQ plans to scale HeiQ Xpectra across Europe, North America, and Asia-Pacific, targeting the global retrofit sector and industrial applications. The product is designed to support compliance with green building standards, and future developments will enhance its usability and aesthetic versatility.
The award will be formally presented on December 4, 2025, at the Maritim Hotel in Düsseldorf. HeiQ looks forward to participating.
