Making the Comparison for Architectural Glazings
PPG Industries has introduced an online tool designed to enable architects to compare the relative energy and environmental performance of common architectural glazings on prototypical buildings. The tool features calculations made according to the U.S. Department of Energy energy-modeling program. It offers a selection of menus that enable users to input variables related to glazing type, glazing design, building location and building type. Once selections have been made, the energy-modeling tool generates a table that contains comparative figures according to glazing type, glazing design and city for a number of
Users can select from 12 North American cities representing various climates. Standard building types include a one-story middle school and an eight-story office building. Glazing options include a complete windowwall or punched windows in six glazing types, including high and moderate light transmittance solar control low-emissivity (low-E) glasses, tinted glass with a passive low-E glass and standard double-lite tinted glass.
Saflex, a unit of Solutia Inc., has developed Saflex SilentGlass Technology, an interlayer designed to cut perceived irritating noise by up to 50 percent. The product combines three interlayers which are designed to decouple and disseminate sound waves. The heart of this patent-pending product is an acoustical interlayer that transforms sound energy into heat energy, which then dissipates. The technology targets sound in the 1,000 to 3,000 Hz range, which includes sounds like car horns, barking dogs, amplified music and aircraft. According to the supplier, utilizing the technology in a window system can result in a reduction of up to 10 decibels in the “transparent” frequency, which equates to up to a 50 percent reduction in perceived sound. SilentGlass is capable of passing Underwriters Laboratory Burglary Resistance Test UL 972 and it blocks 99 percent of UV light.
Vetrotech Saint-Gobain Offering Bigger Sizes
Responding to demand from architects and building owners seeking to incorporate larger interior glazing elements into their designs, Vetrotech Saint-Gobain is now offering its Keralite FR-R and Keralite FR-F fire-rated glass-ceramic in larger sizes. The new 46 x 78-inch sheets join the company’s current offering, which is 30 x 60 inches in size.
Keralite FR-R is a wireless, fire-rated glass-ceramic used in fire-rated locations such as transoms and borrowed lites. Keralite FR-F is a wireless, fire-rated glass-ceramic with surface applied safety film for high impact safety (CPSC category II). It is designed for use in locations where accidental human impact safety ratings are required, such as doors, transoms and borrowed lites. Keralite FR-F provides fire ratings of 20-, 45-, 60-, 90- and 180-minute duration, and is designed to help contain smoke and flames.
A new brochure from Super Sky discusses how the company’s products can offer energy efficient commercial offices and industrial manufacturing sites. The North Light Energy Island produces electricity and provides natural light. Vertical glazing on the shade side of the system produces natural light. Diffused light from the array enhances interior spaces. Photovoltaics can be used in covered walkways, shading parking area, entrances and other applicable spots.
CertainTeed has developed a green building products brochure to help explain the varied roles building products play in commercial and residential construction. The pamphlet discusses the contributions products can make toward sustainable construction and maximization of a building’s useful life. Practical product information regarding recycled content, use of harmful chemicals and third-party certifications is provided.
