Wondering about the formaldehyde content of this stuff.
Given my (admittedly limited) understanding of the topic, adhesives used in glulam are moisture resistant and therefore formaldehyde emissions are low and well within the levels consider safe (i.e. the formaldehyde does not separate from the other parts of the adhesives because of the water resistant nature of the adhesives as a whole). (Here’s a source.)
However, there are a variety of adhesives used in glulam products and yes, some of them contain formaldehyde. (Have another source.)
Just to be thorough, here’s a third source about the standards used concerning formaldehyde emissions in engineered wood products.
