Can someone explain why spray foam seems to be the go-to for US construction? Is it different types of wood/treated vs untreated?
“At the root of the problem are cowboy traders (unlicensed tradesman/contractor) who apply the foam without a full survey or appropriate expertise – but because of lenders’ caution, this is affecting other homeowners who had similar work.” also “because surveyors are unable to inspect the roof timbers behind the layers [for moisture], mortgage lenders tend to issue blanket refusals on properties where any foam is present.” Maybe in the U.S. we just use wood moisture meters to check for moisture?
My impression is that homes in the US tend to have more wood involved in their construction generally, so it seems plausible to me that US construction methods may be more experienced with ways of managing wood moisture
The problem with this style of foam application, is that you cannot get to the wood to check the moisture content, without ripping down the foam (or probing through it, exacerbating any problem).
So there isn’t a way to test. And as there have been problems, the lenders won’t take the risk on any more.
I was thinking the meters with the metal probes that go through yeah. Wasn’t aware that could exacerbate the issue.
