A Conversation Between an Architect and PINKYS Sales
Introduction
When specifying steel doors for residential or commercial projects, energy code compliance requires careful evaluation. U-Factor, Solar Heat Gain Coefficient (SHGC), climate zones, glazing specifications, and overall system design all impact whether a door will meet local building requirements.
Not all thermally broken steel doors automatically satisfy energy code standards. Performance depends on the exact configuration selected.
To clarify how compliance works — and where limitations apply — we spoke with a PINKYS sales specialist about what architects need to consider before specifying steel doors.
Architect & PINKYS: Energy Code Q&A
Architect
I’m working on a residential project that must meet strict energy code requirements. Do your thermally broken steel doors comply with required U-Factor values?
PINKYS Sales
Some configurations can, but not every thermally broken model will automatically meet every jurisdiction’s required U-Factor.
U-Factor measures how well a door system prevents heat transfer. While thermal break construction significantly improves performance compared to non-thermally broken steel doors, the final U-Factor depends on:
- Door size
- Percentage of glass
- Type of insulated glazing
- Frame design
- Installation conditions
Because of these variables, compliance must be evaluated on a project-by-project basis. We recommend confirming performance requirements before finalizing a specific door configuration.
Architect
So simply selecting a “thermal break” option doesn’t guarantee compliance?
PINKYS Sales
Correct. Thermal break construction improves energy performance by reducing thermal bridging between interior and exterior steel components. However, it is just one part of the overall system.
Glass selection, door dimensions, and glass-to-frame ratios all influence final performance values. Some large-format doors with significant glazing may require specific insulated glass packages to meet stricter U-Factor targets.
Thermal break is an important foundation — but it does not automatically ensure compliance without the proper glazing and configuration.
Architect
How does SHGC factor into this, especially for doors with large glass panels?
PINKYS Sales
SHGC — Solar Heat Gain Coefficient — is heavily influenced by the glazing package. Even within thermally broken systems, SHGC values can vary significantly depending on:
- Low-E coatings
- Glass type
- Number of panes
- Gas fills
In warmer climate zones, lower SHGC values may be required to reduce cooling loads. Achieving those targets may require specific insulated glass options, not standard glazing.
Again, compliance depends on the exact configuration selected.
Architect
Do your doors meet California Title 24 requirements?
PINKYS Sales
Certain configurations may meet Title 24 performance requirements, but it is not accurate to say that all thermally broken steel doors automatically comply.
Title 24 compliance depends on:
- Climate zone
- Required U-Factor threshold
- Required SHGC threshold
- Overall door system performance
We work with architects to review the specific project requirements and help identify whether a selected door configuration is appropriate. Final compliance should always be verified with the local building authority.
Architect
How does glass size impact compliance?
PINKYS Sales
Glass area has a major impact. Larger expanses of glass increase the importance of high-performance insulated glazing.
For projects with strict energy targets, architects may need to:
- Select advanced Low-E insulated glass units
- Adjust glazing percentages
- Consider double-pane or enhanced performance packages
Even within thermally broken systems, larger fully glazed doors may require upgraded glass to approach certain performance thresholds.
Architect
Are modern steel doors competitive with other materials from an energy standpoint?
PINKYS Sales
When properly configured, yes. Thermally broken steel doors with insulated glazing can perform competitively.
However, performance should never be assumed based solely on material type. Energy ratings depend on the complete system design. Not all steel doors — even thermally broken ones — will perform the same.
That’s why reviewing certified performance data for the exact configuration is essential.
Architect
What is the safest approach for architects when specifying steel doors for energy compliance?
PINKYS Sales
The safest approach is early coordination and verification.
- Identify required U-Factor and SHGC targets for the project’s climate zone
- Share those targets before finalizing door size and glazing selections
- Request performance data specific to the intended configuration
Avoid assuming that a thermal break designation alone satisfies code.
Architect
When should we involve PINKYS in the design process?
PINKYS Sales
Ideally during schematic design or early design development.
This allows us to:
- Review energy performance goals
- Recommend appropriate glazing packages
- Clarify whether a selected configuration may align with code requirements
- Help prevent costly redesigns during plan check
Energy code compliance is achievable with steel doors — but only when the correct product configuration is selected and verified.
Final Thoughts
Thermally broken steel doors offer improved energy performance compared to traditional iron doors, but compliance with U-Factor and SHGC requirements depends on the exact system specified.
Not every thermally broken model will meet every energy code standard. Factors such as glazing type, door size, and climate zone play a critical role in determining whether a configuration aligns with local requirements.
Careful specification, early collaboration, and verification of performance data are essential to ensure both design integrity and code compliance.
