We're trying to plan for a few things, one of which is whether we should consider some of those whirlybird extractor things on the roof.
So, my questions
- do you have them?
- if you installed them retrospectively, did you notice a difference?
- did you also install ceiling extract vents as well, to work with the whirlybird extractors?
- is there anything you think is important to know *before* installation?
Thanks
