Winter quickly reveals the true quality of an exterior door. Cold surfaces, drafts and condensation are often signs of poor door selection.
Mistake #1. No thermal break
Metal conducts cold efficiently. Without a thermal break, cold transfers indoors, often causing condensation and discomfort.
Mistake #2. Focusing only on steel thickness
Steel thickness alone does not guarantee insulation. Door filling, seals and frame construction are far more important for thermal performance.
Mistake #3. Using an apartment door for a house
Apartment doors are designed for protected indoor environments and are not suitable for direct exposure to cold and moisture.

Mistake #4. Incorrect measurements
Even small gaps significantly reduce energy efficiency during winter.
Mistake #5. Poor installation
Incorrect installation can negate all advantages of a good-quality door, especially in cold weather.
Conclusion: a properly selected exterior door improves comfort, durability and energy efficiency throughout winter and beyond.
