Wayne Dalton Thermospan® Model 125
Wayne Dalton’s Thermospan® Model 125 overhead sectional door features higher thermal efficiency than standard insulated sectional steel doors at a competitive cost. They're also the most rigid doors available with an innovative thermal break that keeps the interior stay at room temperature, resisting corruption from condensation or frost.

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 | 10.79 (★) | |||||||||||||||
|
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.
