Product description

R-Guard FastFlash is a liquid flashing membrane for use in rough openings, to fill joints and seams, to counter-flash waterproofing and air barrier components in new or existing wall assemblies, and to seal around penetrations. FastFlash helps prevent the unwanted movement of water and air through building envelopes. Product available in 29-oz cartridges and 20-oz sausages.

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 FastFlash product is driven by the A1 raw material stage (81-100%) 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.
