Glass greenhouses transmit almost 100% light and glass stays that way for a lifetime or more , compared to 80% with double wall polycarbonate that will gradually fade over time as the polycarbonate becomes more opaque. Due to the weight of the glass covering the glass greenhouse structure is generally stronger than other greenhouses, so it is an excellent greenhouse investment and adds lasting value to one’s property and home. With Glass Greenhouses, you can choose from single layer, double or triple paned glass to improve insulation and ventilation, to help your greenhouse use less energy and to provide better crop protection. Glass is quite inert, in contrast to plastic, and it can function for 40 to 50 years without failure. It is non-combustible, resistant to UV radiation and air pollutant degradation, and it maintains its initial radiation transmission if regularly cleaned. The greatest drawback of glass is its vulnerability to catastrophic losses caused by hail.
