GlassRef

GlassRef is the glass reference for people who sell, specify and install architectural glass: reps, glaziers, fabricators, architects and inspectors. Look up any glass in LBNL's International Glazing Database, build insulating units and laminates layer by layer, see U-factor, SHGC and visible light calculated from the data, and issue a clean spec sheet from your phone. THE REFERENCE • 6,000+ glazing products from 80+ makers, searchable by maker, type, color, thickness and visible light • Equivalents: the closest matches from every other maker • Compare up to six glasses side by side, same units, same rating method • Every value names its source, and the raw data behind any number is one tap away BUILD AND CALCULATE • Makeup builder: laminates and insulating units, layer by layer, with a to-scale cross-section • U-factor, SHGC, visible light, reflectance and UV calculated with LBNL's Windows-CalcEngine • Estimated STC and OITC sound ratings as you build • Spec finder: enter the U-factor, SHGC and light you must meet and see the makeups that do ON THE JOB SITE • Safety-glass stamp reader: point the camera at the etched stamp in a corner of the glass and see what it means: tempered, laminated or heat-strengthened, CPSC 16 CFR 1201 category, ANSI Z97.1 and the maker. The text is read on your device. • NFRC label reader: read the numbers on a window's NFRC label and see what they mean SHEETS AND SUBMITTALS • Spec sheets for any glass or makeup, each with a QR code anyone can scan to see who issued it and whether its data is current • Comparison sheets, submittal covers and your own sheet templates (Pro) • Share a makeup or a glass with a link; no account needed to view it YOUR UNITS, YOUR LANGUAGE • Millimeters or inches; U-factor the NFRC way or U-value in W/m²·K; the rating method printed on every sheet • English, Spanish and Portuguese PLANS Start free: the full library, the builder, calculations, and up to 5 saved makeups and 3 spec sheets.
