Product description
R-Guard Cat 5 is a primary air barrier applied with sprayer or roller to above-grace structural surfaces to produce a highly durable, seamless, elastomeric weatherproofing membrane on exterior sheathing, CMU backup walls, and precast concrete. Proven to prevent water and air penetration of the building envelope in conditions ranging from everyday to the 155-mph winds of a Category 5 hurricane.

R-Guard Cat 5 Rain Screen is a spray or roller-applied primary air barrier designed for use on exterior sheathing behind open-jointed or vented rainscreen cladding. Produces a highly durable, seamless, elastomeric weatherproof membrane proven to prevent water and air penetration of the building envelope in conditions ranging from everyday to the 155-mph winds of a Category 5 hurricane.

Interpretation
Much of the data utilized for this Environmental Product Declaration is based on information supplied by the manufacturer. TrueNorth Collective is not responsible for the accuracy, completeness, or reliability of the data provided by the manufacturer or any information or conclusions derived therefrom.
The cradle-to-gate impacts for the R-Guard Cat 5 / Rain Screen product average are driven by the A1 raw material stage (79-100%) for key impact categories. A3 manufacturing constitutes the second highest driver of impacts for key impact categories.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
