Curved panels should ideally be fixed into four sides : floor/cill, ceiling/head, vertical walls/jambs or an end post.

If the curved wall is secured at the base and only one jamb, an end post should be used as a vertical restraint. (Diagram 1). If the panel can also be fixed at the top, secured into the ceiling, this will offer greater support.

If end glass blocks are used at one end of a curved panel, the reinforcement rods within the panel should be drilled into the top, base and one jamb. (Diagram 2). Introducing double rods will increase the integral strength.

Diagram 2 Arrow denotes position of reinforcement at minimum depths of 25mm
