2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [ 6 ] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through ...

3. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate sheeting in a greenhouse. The second largest consumer of polycarbonates is the construction industry, e.g. for domelights, flat or curved glazing, roofing sheets and sound walls. Polycarbonates are used to create materials used in buildings that must be durable but light.

4. Greenhouse - Wikipedia

   en.wikipedia.org/wiki/Greenhouse

   Greenhouses can range in size from small sheds to industrial-sized buildings and enormous glasshouses. The smallest example is a miniature greenhouse known as a cold frame, typically used at home, whereas large commercial greenhouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with ...

5. Polytunnel - Wikipedia

   en.wikipedia.org/wiki/Polytunnel

   Polytunnels are mainly used in temperate regions in similar ways to glass greenhouses and row covers. Besides the passive solar heating that every polytunnel provides, every variation of auxiliary heating (from hothouse heating through minimal heating to unheated houses) is represented in current practice. The nesting of row covers and low ...

6. Idealized greenhouse model - Wikipedia

   en.wikipedia.org/wiki/Idealized_greenhouse_model

   The idealized greenhouse model is based on the fact that certain gases in the Earth's atmosphere, including carbon dioxide and water vapour, are transparent to the high-frequency solar radiation, but are much more opaque to the lower frequency infrared radiation leaving Earth's surface.

7. Thin-film solar cell - Wikipedia

   en.wikipedia.org/wiki/Thin-film_solar_cell

   Thin-film solar cells, a second generation of photovoltaic (PV) solar cells: Top: thin-film silicon laminates being installed onto a roof. Middle: CIGS solar cell on a flexible plastic backing and rigid CdTe panels mounted on a supporting structure Bottom: thin-film laminates on rooftops Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or ...
