Abstract
A method of manufacturing a multi-layer panel having a curved reflective and/or transmitting facing layer that includes the steps of increasing and/or decreasing pressure on a side of a thin membrane to form a pressure differential across the thin membrane that causes the thin membrane to deform to a required shape; applying a first layer of material to an outer surface of the thin membrane while the thin membrane is maintained in the required shape by the increase and/or decrease in pressure, and allowing the first layer of material to cure for a pre-determined time.
