Geysir® Diffuse is the only insulating glass with a low-emissivity (low-e) coating available on the horticultural market.

This innovative glass achieves an exceptional Ug value of 3.6 W/(m².K) in single glazing, offering outstanding thermal insulation with a thickness of just 4 mm.
Thanks to its low-e coating, which acts like a mirror by reflecting infrared energy inside the greenhouse, Geysir® Diffuse significantly reduces heat loss. Beyond its insulating properties, this new version of Geysir® incorporates light diffusion technology, increasing light uniformity within the greenhouse and enhancing crop growth.
Additionally, this glass can be easily installed on existing greenhouse structures, providing a much more affordable alternative to double glazing, which often requires a complete structural redesign. Furthermore, Geysir® Diffuse is eligible for C2E energy savings certificates, making it an even more attractive option for growers aiming to reduce their energy footprint.
Studies conducted by Wageningen University (WUR) have demonstrated that Geysir® Diffuse reduces greenhouse energy consumption by 20–25%. These results highlight the tangible impact of this product in lowering energy costs and CO₂ emissions, addressing key challenges in the energy transition and decarbonisation goals for greenhouses at both French and European levels.As the only glass on the horticultural market to combine light diffusion with such advanced insulating properties, Geysir® Diffuse meets today’s expectations for sustainability and energy efficiency. With Geysir® Diffuse, we offer a solution that combines innovation, performance, and environmental responsibility, positioning our company at the forefront of sustainable horticultural solutions
