Quote: A semi-related note is venting both kitchen ranges and bathrooms to the roof space, which I would have thought is a Very Bad Thing ™, but seems to be done in 99% houses Venting a kitchen fan into the ceiling space has been illegal for at least ten years. Venting a bathroom fan into the ceiling space is not recommended as you will end up with condensation then mould up there - two things you want to avoid. Stewie Correct, well almost totally correct, you can only vent your bathroom exhaust fans into the ceiling IF you have a tiled roof with no sarking. Given that energy efficiency requirements almost force you to have sarking with tiled roofs ................ BUT, If you have an (opening) window in your bathroom mechanical ventilation is NOT required...But it's still a darn good idea !!! P_D .

And because of the mould and condensation problems it is why I mentioned my Quote: not recommended I think you and I and most others would agree the more ventilation to the outside for these two rooms the better. Stewie go upvc window frames ensure insulation under colorbond. not just sarking, lighter color roof also not sure if you have seen this viewtopic.php?t=5823 last couple of pages… 4 110572 10 years ago was a different software than we use now. it has had a lot of changes over the past years.
