THE CHALLENGES OF FABRICATING CURVED GLASS WITH TIGHT RADII
THE CHALLENGES OF FABRICATING CURVED GLASS WITH TIGHT RADII When it comes to glazing design, architects are drawn to the aesthetic appeal of curved glass. Curved glass is available in many sizes, shapes, and colors. Sharp angle bends up to 90 degrees, radii up to 180 degrees, multiple radii, double to triple reverse bends, and other complex forms make curved glass a exciting design element. However, there are challenges associated with some curved glass shapes, notably curved glass with tight radii. CHALLENGE #1: GLASS THICKNESS The minimum radius is affected by the thickness of the glass to be bent. A simple guideline is the minimum radius can be five to 10 times the thickness of the glass. So, 3mm (1/8”) glass will have a minimum radius of 25.4mm (1”). CHALLENGE #2 LOW E COATINGS The tighter the bend, the greater the possibility of damage to the coating. This surface damage is caused by stretching of the outer surface and co...
