ThermaGlas branded products are engineered specifically for commercial greenhouse applications. Panel widths, thicknesses, pigments, and special greenhouse-specific features (such as guaranteed condensate control) are consistent with commercial growers' needs.
Aside from these commercial greenhouse-specific features, ThermaGlas is the same as Sunlite (for equal thicknesses, weights, and panel widths). Outside of North America, Palram uses the Sunlite brand instead of ThermaGlas.
