What Is Greenhouse Glass?
Greenhouse glass is a type of glass specifically designed for use in greenhouses. It is more permeable to visible and near-infrared rays compared to vinyl or clear plastic, and it efficiently absorbs far-infrared rays. This makes glass greenhouses particularly suitable for growing plants in colder weather or climates due to their enhanced weather resistance.
Typically, greenhouse glass is produced using the standard float glass process. However, some greenhouse glasses come with a special film attached, reducing the transmission of infrared rays to control temperature rise inside the greenhouse while allowing essential ultraviolet rays for plant photosynthesis to pass through. An additional safety feature of this glass is that it does not shatter into dangerous shards upon breakage.
Uses of Greenhouse Glass
Greenhouse glass is primarily used in the construction of roofs and walls for greenhouses in various settings, including crop cultivation, botanical gardens, research facilities, farms, plant factories, and aquaculture for fish and shellfish. Some greenhouses use rubber gaskets in their construction to secure the glass, enhancing airtightness and wind resistance.
Proper ventilation is crucial in greenhouses. Skylights, projecting windows, sliding windows, and ventilation fans are commonly used features. Effective airflow management inside the greenhouse is essential, along with heating and irrigation systems.
In addition to temperature regulation, small indoor greenhouses offer benefits like protection from dust, dirt, pests, and an aesthetically pleasing display within a glass enclosure.
