Greenhouse Glass Panels

Ever since the 1851 Great Exposition in Hyde Park, England, the English have been smitten with greenhouses. At the Crystal Palace, visitors from around the world came to admire this iron and glass greenhouse as the mark of the industrial revolution. This impressive structure was constructed by the famous gardener, Joseph Paxton. The greenhouse was more than 1,800 feet long and comprised more than 900,000 square feet. Inspired by its elegance, the Brits took to building greenhouses on their properties. Quickly, having a greenhouse became a staple status symbol in England. Today, having a greenhouse in England is as commonplace to a home as having a pool in California. Even though there are many coverings for a greenhouse, most of us Brits use greenhouse glass panels for their endearing romantic look.

Glass Type

Selecting what type of glass to use in the doors, windows and structure of a green house is important. Annealed glass is the most primitive. This glass is often used in glass vases and kitchen cabinets. When annealed glass breaks, it shatters into sharp and jagged pieces. Although manufactures sell annealed greenhouse glass panels, it is not recommended by the professionals.

Another type of glass is tempered glass. Tempered glass is extremely strong and resistant to breaking. However, when it does break it only breaks into small squares, which is much safer. Tempered glass is a top choice among many professionals.

Laminated glass is a popular glass used for greenhouse glass panels. It consists of two pieces of glass that are fused together with a polyvinyl butryal interlayer. An impact to laminated glass will cause a spider web appearance, and the glass does not fall from the frame. This is the glass that most car windshields are made of. Many building codes require laminated glass in greenhouses. This is because of safety. If the tempered glass in a greenhouse roof should break, it will not land on anyone’s head. In addition to safety, laminated glass removes 99 percent of harmful UV rays.

Greenhouse Panels

Greenhouse glass panels can be either single pane or double pane. Also known as monolithic, single pane panels only consist of one piece of glass. This application is not recommended in locations where there will be water or wind touching the glass. Should there be snow, the cold temperatures will pass into the home.

Double pane panels consist of two pieces of glass and are insulated. The air space between the two panels of glass creates the insulation. This is the most common application used today for new windows. Since hot and cold air have to pass through space and a second window, double pane panels help regulate interior temperatures.

Glass Tint

In general, there are two categories of tint for greenhouse glass panels: color tint and low-e. Color tints are usually chosen for aesthetic appeal. Residences in coastal areas may choose greens or blues to enhance a maritime look. Bronze and gray tints are commonly used to control light and for privacy. Other less common tints are available, such as reds and purples.

The new technology of low-e glass has become popular because of its many benefits. Barely visible to the naked eye, low-e glass reduces sunlight and cuts down on extreme heat build-up. Low-e glass also reduces the amount of UV rays that penetrate a room. As a result, draperies and furniture do not fade. Low-e glass has become the benchmark for greenhouse glass panels.
