December 5, 20223 yr Mmm, im beginning to think a daft question. Is having formaldehyde in a Warm roof OSB board anything to be concerns with? Normal OSB3 board form China (with formaldehyde) seem to be a third cheaper than Scottish OSB3 (without formaldehyde). I'm presuming that the formaldehyde replacement is very expensive taking delivery from China into account. Regards Warren.
December 5, 20223 yr I paid extra for the non-formaldehyde boards when boarding my loft (cold roof, that one). Logic at the time was that even if I'm not up there much, I'd be cutting and fiddling around with the boards plenty during the installation. Still, it's probably mostly marketing.
