DynaGlas® SolarSoft™ Max

Highest daily light integral (DLI) & guaranteed condensate control for horticultural applications

DYNAGLAS SolarSoft Max is a revolutionary breakthrough in the horticultural industry. It is the first corrugated polycarbonate greenhouse covering to be tested for hemispherical light transmission by world-renowned Wageningen University and Research Center.


Compared to flat coverings, DYNAGLAS SolarSoft Max’s Greca style corrugation allows excellent light transmittance at low sun angles, while maintaining hemispherical light transmittance up to 78 percent. Combining this corrugation with a unique proprietary formulation allows the DYNAGLAS SolarSoft Max sheet to provide 90 percent light dispersion while maintaining 90 percent light transmission. This results in a deeper penetration of light that is evenly dispersed into the plant canopy, ensuring consistent growth for your crops.


More Light, More Evenly Dispersed

Highest DLI Value of Any Diffused Polycarbonate Sheet In the Industry

DynaGlas SolarSoft Max's white color allows for maximum light transmission while eliminating shadows and reducing unwanted solar heat gain. As light transmits through the sheet, the SolarSoft special pigments diffuse the light so that it spreads in many directions. This allows more evenly dispersed light throughout the greenhouse and less stress caused by direct sunlight, resulting in an ideal growth environment.
