Facing materials are applied to fiberglass blankets to serve as a vapor retarder or barrier as well as a protected cover over the fiberglass insulation. Facing material offers a clean finished look in any metal building environment. There are several facing options to choose from, however, WMP®-VR-R Plus is a common standard facing and WMP-50 is a common heavy duty facing.

Tabs
Tabs are the extension of the vinyl facing past the fiberglass insulation blanket, used to seal or create a finished edge for the seams. You can get 1-6” tab on one side of the fiberglass, or 2-3” tabs. Double faced tape can be added to seal the tab to next piece of insulation. In retrofit this is usually 3” on each side and 6″ on one side in new construction. In Retro-Fit, It is either tucked up along the side of the fiberglass acting as a trim or used to cover the the purlin or girt. An option is to get a factory pre-applied adhesive on the tab, which the installer peels and sticks to the next blanket. This provides a clean seal to the seams and creates a vapor barrier.
