Low VOC structural adhesive options? – GreenBuildingAdvisor

Hi all,

My 2nd floor framing plan will likely require lots of structural adhesive. As part of an exposed timber frame floor I’ll be using it to build 2 and 3-ply joists, as well as to glue down the exposed 2x decking, and subfloor above that. Since these elements are exposed, I’d like to minimize any harmful VOC’s/toxicity, etc from the adhesive. 

Does anyone have experience specifying or using “green” adhesives in a structural capacity? 

Is LEED a pretty good standard for finding low toxicity adhesive, or is it just green washing?

How much do I even need to rely on the adhesive anyway? For the subfloor I’m not too worried about adhesive strength, but for the built-up joists I’m guessing it’s more of a factor (in addition to using fastening schedules). 

I’ve noticed some brands report shear strength (this is what I’m relying on in the joists) some report tensile strength (this is a factor in the subfloor), and some manufacturers are LEED approved.  Any idea what strength value I should look for?  

thanks!
