Understanding what makes a door system energy efficient:

1. What is the U-Factor?
The numbers look small, but a 0.12 U-Factor MASTERCRAFT® 6-Panel Steel Door is 29.5% more energy efficient than our competitors 0.17 U-Factor doors.

2. What is the core material?
Unlike styrene cores that are stamped out leaving voids throughout the door, polyurethane cores are blown into the door to ensure every square inch of the door is properly insulated.

3. What are the rails made of?
Doors that utilize steel components between the inner and outer skins are more prone to frost issues, rust and mold. Composite materials create a thermal break and reduce the amount of thermal conductance.

4. What is the door skin made of?
If the core material is the same, steel doors tend to be more energy efficient than fiberglass due to the increased amount of foam that can be placed inside the door.

MASTERCRAFT ®Competition
Composite Top Rails:
Reduces thermal transference through the door.
Wood Top Rails:
Less efficient, allows more thermal transference through the door.
Polyurethane Core:
Designed by DOW to give us one of the most energy efficient cores in the industry.
Styrene Core:
Less energy efficient due to gaps around the lockblock and edges of door.
Composite Bottom Rails:
Reduces thermal transference through the door and moisture build up.
Steel Bottom Rails:
No thermal break. Prone to frost build up, rust and mold.
