I have blinds. Do I still need solar films?

Sun Block, Inc.: Window Films that Unlock the Natural Beauty...
While blinds are effective at reducing the amount of light in a room, they are very poor at reducing the heat gain, even with insulated blinds. This is because there is a 4" to 6" gap between the glass and the blinds. Heat builds up in this area, and radiates through the blinds. This heat can be considerably greater than the outside air.
