If your topping off your coolant every fortnight then try topping it up when the engine is cold and then leaving it over night. As the temperature drops over night so dose the pressure, this will increase the pressure when the engine is hot ( there should be a one way valve on the radiator / explanation cap) meaning that the water is less likely to boil off and thus you won't loses coolant. It's a free fix and worth a go if you can leave the car to cool complete and then leave it over night.
