I know Mylar is the best reflector and after that would be smooth white paint.

But i was in a shop today and they were selling Thermal Blankets.Very thin

Im not to sure of the material but they are coated with aliminium,

Would these work well if i taped it to some card board and hung it above my lights to shine the light down?
