Glass Performance
Performance criteria
Evaluate the complete glazing assembly.
Performance values depend on the whole build-up, support system and calculation or test method. A value published for one pane should not be applied automatically to an insulating unit, window or façade.
Structural
Design pressure, support, glass strength, allowable stress, deflection, duration and load combination.
Safety
Impact classification, breakage pattern, post-breakage retention, overhead risk and fall protection.
Thermal & solar
U-value, SHGC or g-value, shading coefficient, visible transmission and surface temperatures.
Optical
Exterior reflection, colour, distortion, haze, anisotropy, coating appearance and visual mock-ups.
Acoustic
Rw or STC target, spectrum adaptation terms, pane asymmetry, interlayer and complete-frame performance.
Durability
Edge exposure, seal compatibility, temperature, moisture, altitude, cleaning and service environment.
