ThermaGlas™ Opaque Multiwall Polycarbonate

100% opaque panels for light deprivation applications

THERMAGLAS Opaque is a 100% opaque multiwall polycarbonate panel engineered for crops or species requiring complete light deprivation, or for applications requiring security against visibility from outside the structure. Lightweight and easy to install, our insulated panel accommodates a wide range of temperatures.

 

With a highly reflective, white outer skin and a black core, THERMAGLAS Opaque ensures 0% light transmission, yet allows for high reflectance for interior lighting. Its multiwall design offers insulation to help maintain consistent temperatures inside your structure. THERMAGLAS Opaque is a durable solution for specialty greenhouses, storage areas, and more. This product is also warranted for 10 years to not allow direct sunlight to pass through the panel.

Light Deprivation Solution for Cannabis Cultivation

Due to the recent developments in the legalization of recreational and medical cannabis, growers are faced with several growing challenges. Commercial cultivation of cannabis requires full control over the day and night cycles. During daylight cycles, growers in the commercial market strive for maximal light transmittance and high light diffusion factors. Opaque walls are desirable for security and discretion, as well as for light deprivation control.

Palram provides a suite of solutions for cannabis growers with specific high-light transmission and diffusion panels for the roof; and opaque, reflective multiwall for greenhouse walls and gables.

To learn how to achieve complete light deprivation, read our Controlled Cannabis Light Deprivation with Polycarbonate Multiwall Panels article.
