Fire-Rated Glass & Glazing Products
Some of the key elements in building design and renovation are light, open environment, visual safety, and communications. Virtually all of these require the use of glass. In the past, designers had limited options under the building codes. Today, with so many new fire-rated glazing systems available, design freedom is at the fingertips of the creator.
North American building fire codes are built upon the concept of compartmentalization. Thus, fire-rated glazing materials are intended to help compartmentalize fire and smoke in a building. A fire rating is determined by the length of time a product can meet fire endurance testing to either fire-protective or fire-resistive US and Canadian building standards. The fire-protective or fire-resistive ratings mandated by most major codes are based on the application requirements. These requirements depend on how much time is necessary to maintain the structural integrity of the building, property protection, and safe egress of its occupants.
Fire-rated glazing materials carry a label on the glass that may include the manufacturer, listed fire-rating, safety standards, test standards and testing agency. There are a number of fire-rated products that will meet all the necessary fire-rated building code requirements. These products are divided into fire-protective and/or fire-resistive categories.
Fire- Rated Glazing
Acid-etched glass combines a satin finish with a neutral, translucent appearance. The result is a softly filtered light effect that smoothes visual corners and creates distinctive silhouettes. Acid-etched glass provides obscurity and privacy for a range of interior and exterior applications.
Acid Etched Glass
These products feature distinctive patterns added to clear glass to create stylish textures and effects with varying degrees of privacy and diffusion. When ultratransparent glass is used as the base glass, the product can achieve high light transmittance.
Distinctive Low Iron Patterns
AGC's painted glass products offer a colorful, opaque glass appearance that is perfect for a range of decorative interior applications. By applying a high-quality paint to the back of its Krystal Klear low iron float glass, AGC creates a product that beautifully combines form with function.
Silk-screened glass can add function and beauty to any project. Used for its decorative attributes, ability to reduce solar heat gain or act as a sun screen, silk-screened glass can add character to any project making it uniquely yours. Silk-screens are available in a variety of standard patterns including dots, holes, and lines or custom patterns with a wide range of colors.
This decorative product is manufactured in a process similar to enameling. An enamel coating is applied to part of the glass using a screen and is vitrified during the tempering or strengthening process.
Mirrors are manufactured by applying a reflective coating to a suitable substrate. The most common substrate is glass, due to its transparency, ease of fabrication, rigidity, hardness, and smooth finish. The reflective coating is protected by the glass on one side and an optional protective paint on the other. Glass mirrors are usually coated with non-toxic silver
A laminated glass is an assembly composed of at least two panes of glass bonded together across their entire surface by an interlayer. For laminated safety glass, the most widely used interlayer is a plastic PVB (polyvinyl butyral) film, but EVA (ethylene vinyl acetate) films or a safety resin may also be used. In the event of breakage, the bond between the glass and the interlayer ensures that the broken pieces remain in place—at least for a certain period or up to a specified load level.
According to standard ANSI Z97.1, a laminated glass may be considered a safety glass if it meets the requirements of a specific resistance class following the pendulum impact test detailed in this standard. In some specific cases, tempered or heat-strengthened glasses are used to manufacture laminated glass. As such, in specific applications requiring a high level of compression, a laminated glass composed of tempered and heat-strengthened glass is sometimes used. The former provides mechanical strength, while the latter gives adequate residual stability if the glass breaks and cannot be immediately replaced. Heat-strengthened laminated glass is sometimes used when a higher level of wind load resistance is required than that offered by annealed float glass—as well as to prevent the risk of breakage due to thermal shock.
