Annealed glass, heat strengthened glass, tempered glass and insulated glass are the main types of glass used on buildings. Each has unique properties and applications. Strength, breakage pattern and thermal properties are key variables. This article will focus on:
Insulated glassGlass is insulated in order to give it improved thermal properties. Today most architectural glass is insulated, even in warm climates where it helps with cooling loads. To insulate glass, cut two pieces the same size, clean them, place a dessicant-filled spacer between them, and use one or two layers of sealant to hold the glass together. This seals the airspace between the pieces of glass, creating an insulating layer of dry air. Sometimes this airspace is filled with an inert gas such as argon for better R value. Insulating glass can also be fitted with newer “warm-edge” technology, where the spacer, dessicant and sealant are combined into one material, a thermoplastic which is applied to the glass in a near-liquid state. This improves thermal properties at the glass edge, improving overall window thermal performance.Much more could be said about all of these technologies. Indeed your Chicago Window Expert has enthralled scores of cocktail party attendees with much more lengthy discourses on these subjects (“Hey come back! Where you going? I’m not done yet!”), so I will stop here for now.
