Dear all,

Does the silicone sealant used for the glass block installation need to comply with the maximum VOC requirements of this credit? if it does, it includes in which type of adhesive, is it structural glazing or special purpose contact adhesive or what? please comments on this.

Many thanks,

Is the sealant inside of the weatherproofing system and applied on-site? If so, then it does need comply. I don't have experience with this particular product, so perhaps someone else knows where this would fall?

I don't know the meaning of inside the weatherproofing system, but the silicone sealant will be applied on site and it will used inside and outside of the building (glass block installed on wall, between indoor and outdoor)

Inside the weatherproofing system means within the space people will be occupying, inside the water, vapor, or air barrier(s). So this would qualify as inside the weatherproofing system. Thus I would say it does need to comply with the VOC regulations, but I'm still unsure which category it would fall under.Anyone else?
