ThermaCore Heavy Duty™ is a structural‑grade hybrid insert combining high‑performance GPS insulation with integrated 16‑gauge galvanized steel reinforcement. Engineered to replace traditional steel skeletons in vinyl, fiberglass, and hybrid frames, Heavy Duty provides superior load‑bearing strength, secure fastener anchoring, and enhanced thermal performance in a single, precision‑cut component.

NFRC Simulation Input Summary
ThermaCore Heavy Duty™ (Steel‑Reinforced Hybrid Insert)
Material Type:
Composite hybrid insert consisting of closed‑cell polyurethane or GPS foam with integrated
galvanized steel reinforcement.
Thermal Conductivity (Foam Component): Polyurethane: ~0.024 W/m·K | GPS: ~0.028 W/m·K
Thermal Conductivity (Steel Component): Galvanized Steel: ~50 W/m·K
(modeled as discrete reinforcement, not continuous insulation)
R‑Value (per inch, foam component only): Polyurethane: ~7 | GPS: ~5.0
Density: Foam: ~30–60 kg/m³ (PU) | ~15–30 kg/m³ (GPS)
Steel: 16‑gauge galvanized (approx. 1.5 mm thickness)
Moisture Absorption: Foam: Very low (closed‑cell structure) | Steel: Zinc‑coated for corrosion resistance
Fire Rating:
Foam component available in formulations meeting:
ASTM E84 / UL 723
CAN/ULC S102
