Highlights
| Material | Steel | |||||||||||||||
|
R-Value ? R-value measures how well a material resists heat flow: the higher the R-value, the better the insulation. For doors, a higher R-value helps improve energy efficiency by keeping indoor temperatures more stable. R0-R6 = 1 star | 12.12 (★★★) | |||||||||||||||
|
U-Factor ? U-Factor measures how well a door keeps heat from escaping. The lower the number, the better the insulation. Unlike R-Value, which only measures material resistance, U-Factor reflects the performance of the entire door system, making it a more accurate measure of energy efficiency.
