Description
Preboard FR with Graphite Polystyrene (GPS) for the best, long-term thermal protection plus these high performance benefits.
Fire-Resistant Performance
- Specifically formulated to not require a thermal or ignition barrier when installed on any interior wall surface
- In thicknesses up to 2.28,˝Proboard FR meets testing to NFPA 286 in accordance with IBC 2015, Section 2603.9 and IRC 2015, Section 316.6.
- Can be installed and left exposed when used in internal applications, making it the ideal insulation for areas left unfinished
Thermal Performance
- Proboard FR’s GPS core provides a powerful R-5 per nominal inch.
- Minimizes energy loss (conduction) from“thermal bridging”
- Reflective back facer adds rigidity and boosts thermal performance (with appropriate airspace).
- R-Hold™Technology ensures R-value performance remains permanent
- Does not deteriorate, breakdown or lose thermal performance over time like other insulation
- Does not “off-gas” like other foams that rely on gases to deliver thermal benefits–meaning the gases used in manufacturing other insulation products slowly disperse from the foam causing loss of R-value and performance degradation
