1 BENDS AND CURVES
Terminology
To assist in understanding glass bends, the following terminology is used to describe the measurements and characteristics of bent or curved glass.
| Height | The straight edge length of a bend. |
| Girth | The distance around the circumference of the fence. |
| Depth | The distance between the apex of a bend and a line across the edges of a bend. |
| Radius | A line taken from the centre of a circle to the circumference of the circle. |
| Degree | The size of the segment of a circle expressed in degrees. |
| Tangent | A straight line coming off the arc of a curve |
| Chord | The straight distance between the edges of the curve. |
Ordering Requirements
- Provide all the measurements listed in the terminology if possible. If not all are available at least provide the radius, girth or chord and height measurements, and usual glass data: type, thickness, edgework, holes, notches, quantity, application and any special requirements.
The measurements must state if they are to the outside or the inside surface of the glass. - Provide a template of the radius or shape of the curve, and height measurement. Indicate if pattern measurement is to the inside or the outside of the glass. For shaped bends, provide a template of the shape and mark on the radius and all other details.
Glazing Notes
Special requirements apply to glazing curved glass, as the glass radius and the rebate radius are rarely the same. In addition the radius at the head can differ from that at the sill, it is critical that rebates are produced of sufficient size to accommodate all variances.
Do not wedge glaze. Wet seal only with silicone or other suitable sealant. If in doubt consult MetroGlassTech for glazing recommendations.
