The top half of a RUSS strip is mechanically fastened to the roof, while the bottom half is primed so the membrane can stick without fastening. Most building owners only encounter the term RUSS when discussing manufacturer specifications in replacement proposals.
The most important function of RUSS strips is to prevent bridging. Bridging creates tension in the membrane that can lead to premature failure at one of the most common leak sources: the roof’s perimeter.
