Thermal Package

Thermal break technology and high-performance insulation options for year-round comfort.

Thermal Guard™

Thermal Guard™ is an enhanced insulated iron door system designed to improve energy efficiency and reduce heat transfer in critical areas of the door assembly. In this configuration, the door jamb and threshold/kickplate are thermally broken, helping minimize temperature transfer between the exterior and interior sides of the entry system.

By incorporating thermal barriers into the frame and lower threshold area, Thermal Guard™ significantly improves comfort and reduces condensation compared to traditional iron doors, while maintaining the strength and beauty of custom steel construction.

Thermal Guard™ Features

  • Thermally broken door jamb/frame
  • Thermally separated threshold and kickplate
  • Insulated door construction
  • Improved energy efficiency
  • Reduced condensation around frame and sill
  • Enhanced comfort in hot and cold climates
  • Ideal balance of performance and value

Thermal Guard™ is an excellent solution for homeowners seeking improved thermal performance without a fully thermally broken door system.

Thermal Guard Max™

Thermal Guard Max™ represents the highest level of thermal performance in luxury iron door construction. Unlike partial thermal systems, the entire door assembly is thermally broken — including the door panel, frame, threshold, and structural metal components.

This advanced engineering system separates interior and exterior metal surfaces using high-performance insulating barriers throughout the entire door structure, dramatically reducing heat transfer, condensation, and energy loss.

Thermal Guard Max™ Features

  • Fully thermally broken door panel
  • Thermally broken frame and jamb
  • Thermally separated threshold and kickplate
  • Complete interior-to-exterior thermal isolation
  • High-density insulated core
  • Superior condensation resistance
  • Maximum energy efficiency
  • Enhanced acoustic insulation
  • Premium comfort in extreme climates

Why Thermal Guard Max™ Matters

Traditional iron doors can conduct exterior temperatures directly through the metal. Thermal Guard Max™ eliminates this issue by creating a continuous thermal barrier across the entire system, keeping interior surfaces more comfortable year-round. This results in lower energy consumption, reduced HVAC load, improved indoor comfort, better long-term performance, and reduced expansion and contraction from temperature changes.

Thermal Guard Max™ is the ultimate solution for luxury homes, coastal environments, humid climates, and energy-conscious projects demanding the best in both design and performance.
