Glazed-in, controllable passive ventilation to reduce condensation

Hi there.
I’ve read through your answer to the FAQ about reducing condensation, and it’s very well written. I agree with the opinion that going to the expense of installing a forced air or heat recovery system is often not warranted.
You touch on achieving cross-flow passive (natural) ventilation by opening windows and using security stays for added security, which is correct, but I’d also like to draw your attention to the option of installing trickle (passive) vents in the windows. This is a very cost-effective way of providing continual cross-flow ventilation, without any of the security concerns from open windows. They also come with integrated insect mesh to keep insects out.
Fitting out a typical single storey 3 bedroom home will cost the owner around $800 – $1000, so it’s a great cost-effective solution with no ongoing running costs and maintenance.
Thanks,
Matt Cox

Thanks for your comment Matt. We agree that it is important to include trickle vents in windows, particularly when there are double glazed units.
