Polymer material for coating hot greenhouses
WebGreenhouse Polycarbonate Panels. Polycarbonate panels are made from clear, rigid plastic that transmits light almost as well as glass. Panels are typically available as flat twin-wall panels, which contain two flat polycarbonate panes separated by an air space. The air space between panes improves the insulation properties of the panels.

WebMaterials used to glaze greenhouses and hoophouses have different transmission properties, including ultraviolet (UV) radiation. Approximately 4% of the sun’s radiation output is as UV, but since the ozone layer absorbs most UV-B (280-315 nm) and all UV-C (100-280 nm) radiation, about 95% of the UV we receive is UV-A (315-400 nm). To … Web2. Caveat: This answer assumes that the green plastic shown is pigmented green and thus transmits green light into the greenhouse. Certain metal coatings could reflect green light but transmit blue and red wavelengths …
