judging wall on wood moisture content
Calina, Although, as you say, water content is not a good guide for insulations as some are hygroscopic and some are not, I have been thinking the water content of the wood sheathing (plywood or osb or panelvent) is a reasonable guide in that timber decay is likely if water content goes above 20%. F...

Daniel, I assume you mean in the insulation closest to the ventilated cavity rather than in the cavity itself? Lee, I had a go at many varying timber frame buildups with the 1% rain leak keeping u-value at 0.22 and using many varying buildups as wufi is really good at multiple cases. Definitely arri...

Hi Calina, Many thanks for taking the time to reply in detail to the tough questions. Good to know the values for coatings now. (BTW that link to the other article does not seem to work for me.) Trying extremes of range makes sense to see what happens with leaks. Will try the A-value adjustment and ...

Coatings and cavities
Hi Joseph and Calina, Playing around with the wufi parameters makes for interesting results but being confident that the parameters are correct is a challenge even if they are available. As clear in "Breaking the Mould V" and from course, driving rain penetration is key to weather a wall f...
