A well- designed overhang may be all that is necessary to shade the glazing in the summer. Compared with sloped glazing, vertical glazing is less expensive, easier to install and insulate, and not as prone to leaking, fogging, breaking, and other glazing failures. Vertical glazing is often more aesthetically compatible with the design of existing homes. Sunspace Components Glazing Glazing is the clear or translucent material that allows sunlight to enter and warm the space. Glass is the most common glazing material, and many sunspace builders choose glass for its durability, clarity, and appearance.
Some plastics even transmit solar energy more effectively than glass.
Deciding on which glazing to use is only the first step in the decision-making process, however. Advances in glazing technology make it possible for designers to fine-tune performance by choosing glazings that meet the specific needs of their projects. Historically, manufacturers have used multiple layers of glass to improve the insulating value of a window. Low-e coatings are applied to the surface of glazings or to films suspended in the airspaces between the panes of glass. They reduce radiant heat loss and gain and dramatically improve a window's insulating value.
