Phenolic insulation is a premium, rigid closed-cell foam insulation known for having the highest thermal efficiency of any commonly used insulation material. It is widely used in commercial and residential walls, roofs, and HVAC ductwork, especially where space is at a premium. 

 

Key Performance Attributes

 

FeaturePerformance Details

. Thermal EfficiencyReaches ultra-low thermal conductivity (approx. 0.018 to 0.022 W/m·K).

. R-Value per InchDelivers an exceptional R-6.5 to R-8+ per inch, outperforming PIR, XPS, and fiberglass.

. Fire SafetyExcellent fire performance. As a thermoset material, it chars rather than melts, producing minimal smoke.

. Moisture ResistanceClosed-cell structure (>90%) provides excellent resistance to water vapour and condensation.
