Karel Vollers, Delft University: Glass Reflections in Articulated Buildings
Reflections can be spectacular, especially on freely curving facades. Many computer-animated designs show a play of geometry and colors, which differ greatly from that on the realized facade. The glass industry, as to regularity of glass reflections, only partly meets an architect’s wishes. Often distortions like pillow working (by air pressure differences), production defects (like tempering induced waving of the pane, caused by rolling bars and trailing ends), etc., cause blurring of the reflected image. Design decisions will be elaborated on that help in the facade appearance, and can be used to hide this fragmenting and deforming, or alternatively, to use them as part of the expression of the architecture. An inventory of distortions on panes is shown here, with ways to minimize their individual causes. Some aspects are illustrated with glass-bending projects, for example a cold bent facade system (glass and alu framing) and the new framing system Alcoa AA100Q-Twist with freely curved glass and opening windows. Regularity of reflections on architectural glass is than compared to that on automotive glass.
