If it breaks, it shatters into little, rounded pebbles rather than unsafe jagged fragments, making it the industry standard and building-code requirement for doors.Low-E Glass: Low-Emissivity (Low-E) glass features a microscopic, transparent metal finishing that shows infrared light (heat) while permitting visible light to travel through. This keeps homes cooler in the summertime and warmer in the winter season.Frosted and Textured Glass: Ideal for bathrooms, bed rooms, or entrances where personal privacy is desired without compromising natural light. Textures vary from subtle raindrops to heavy ripples and geometric patterns.Laminated Glass: Consisting of two panes of glass with a long lasting plastic interlayer (PVB) sandwiched between them, laminated glass offers exceptional security versus forced entry, obstructs UV rays successfully, and supplies exceptional soundproofing.Glass Type Comparison TableGlass TypePrimary BenefitBest Used ForPersonal privacy LevelTempered GlassSecurity and impact resistanceAll exterior French doors (Building Code)None (Clear)Low-E InsulatedEnergy effectivenessSevere environments, outdoor patio doorsNone (Clear)Frosted/PrivacyLight transmission with personal privacyBathrooms, street-facing entrancewaysHighLaminated GlassImproved security and soundproofingHigh-crime areas, noisy urban environmentsNone (Clear)3.
