PROSOCO's R-Guard System Now Carries Declare Labels

Words: Anonymous Anonymous

PROSOCO has announced that it now offers a complete R-Guard air and water barrier system whose components all carry Declare labels.

If you’ve ever been involved in a Living Building Challenge project, you are likely starved for a simpler process of specifying and documenting material ingredients.

PROSOCO knows from experience what that process looks like: pages and pages of submittal forms, layers of reviews, and tedious back and forth between designers, manufacturers, consultants, engineers, distributors, and on and on. And that’s just for one product!

The International Living Future Institute (ILFI)’s Declare product database simplifies that process significantly. You could either complete countless forms, specification documents and emails, or simply look up the Declare ID for a product. That’s it, you’re done. It’s almost like having a magic wand to cut through all the clutter.

That’s why PROSOCO has invested so heavily in the ILFI’s Declare ingredient transparency program, because the company will whole-heartedly endorse something designed to maximize your project team’s efficiency.

Now that every component of PROSOCO's Cat 5 system (Joint & Seam Filler, FastFlash, AirDam, Cat 5 and now PorousPrep) features an ILFI Declare label, specifying an ICC-ES-conformant air and water barrier system is simpler than ever.

PorousPrep, a water-based sealer for raw gypsum board edges, has been used on two Living Building Challenge projects — the R.W. Kern Center at Hampshire College and the Bullitt Center.

Time is money. This system is optimized for ease-of-use on the jobsite. To find out how it’s used, check out this handy R-Guard FastFlash system application video.

You can find the Declare ID numbers for all 13 of PROSOCO's products that carry a Declare label at the ILFI Declare Product Database. You can also read more about all of the ways PROSOCO is committed to promoting transparency in construction on their Sustainability page.
