I've had a window company in to replace my original 55-year old windows. They didn't recommend trickle vents in any of the windows purely on aesthetic grounds. I insisted on at least one window with trickle vents (the large window on the side of the house).
Is this likely to be enough for 'secondary ventilation'?
The original windows that are being replaced had no trickle vents.
