The function of sunroom glass is to collect sunlight while preventing harmful rays from coming through. For an all-season sunroom, the purpose of glass in the winter is to keep warm air in the sunroom while keeping cold air out.
Types of Glass
- One layer of glass is referred to as single glazing. Single-glazed glass does not have sufficient insulating properties and therefore is not often recommended for four-season sunrooms.
- Double-glazed (double layers) glass comprises two layers of glass that has either air or gas between the two panes. This prevents air from moving between the layers and better insulates the room in winter and reduces condensation.
- Triple-glazed (triple layers) glass insulates better than double glazed because it has three layers of glass with two spaces where air or gas are filled.
- Argon-filled windows involve a glazed window with the space between the glass filled with argon. Argon provides lots of insulation because it is a dense gas that prevents a air from passing through.
- Low-E (low emission) glass is a chemically coated glass that a llows light in but blocks radiant heat and energy. Low E is great in that it obstructs harmful UV rays. Low E can be clear or found in a variety of tinted tones, which can further minimize the sun's glare.
- Tempered glass is a type of safety glass that can be standard in some sunrooms. When tempered glass shatters, it will break into very tiny pieces, reducing the possibility of injury.
Glass technology has lead to products that are more affordable, durable, energy efficient and safe. Glass is not only architecturally stunning, but it is practical in that it is naturally cleaned by rain. Consumers can purchase glass that better reduces glare and heat, insulates and meets modern safety requirements.
