Thermally Broken Steel Door Guide
A thermally broken steel door uses a profile designed to reduce direct conductive heat transfer through the metal frame or door system. Thermal-break construction can be important for cold-weather projects and other applications where condensation and thermal performance are design considerations.
What to confirm
- Whether the selected door uses a genuine thermal-break profile
- Exact frame and door construction
- Glazing type and insulated-glass configuration
- Low-E or other glass options, where available
- Weatherstripping and threshold details
- Project-specific energy or code requirements
- Current test reports or ratings mapped to the exact model, where required
Thermal break does not automatically establish a whole-door rating
A thermal-break profile, insulated glass, or Low-E option does not by itself establish a whole-door U-factor, NFRC rating, code compliance, or project-specific energy performance. Those claims require current documentation for the exact tested configuration.
Cold-weather ordering
For projects in colder climates, provide the project location, wall construction, required size, swing, glazing needs, and any specified performance criteria before ordering.
