P.S for green house glass features
Greenhouse glass traps heat energy in the same way that our planet’s atmosphere keeps us warm – through light wave transformation, and through convection of the air inside the greenhouse. Solar radiation reaches the greenhouse, passes through the glass, and gets absorbed by the ground and plants inside the greenhouse. The ground and plants transform the solar energy, and convert it to heat energy, which cannot escape through the glass.
Glass greenhouses tend to be semi-permanent structures that will cost more to build initially, but will hold up better over time,and be durable to weather and age
Greenhouse glass is typically tempered for safety. This means that it has been laminated, similar to a car windshield; if it breaks, it crumbles into small pieces with relatively smooth edges that are less likely to cut your skin than large, jagged shards. Tempered glass is highly recommended for greenhouse applications, since the glass will be installed overhead and subjected to wind, hail, and stress from snow weight in colder climates.
In addition, greenhouse glass may have a low-E glazing applied. Low-E glazing is a thin, semi-transparent layer of metal that reflects most UV and some infrared light back into the atmosphere, while still allowing visible light to penetrate into the greenhouse. By blocking the more intense UV waves, low-E glass can protect tender seedlings from receiving too much solar radiation. Low-E glass also helps to maintain a more constant temperature within the greenhouse by blocking some incoming infrared, or heat waves. With proper ventilation, low-E glass can help prevent the greenhouse from getting overheated.
