Performance Data


U-Value

A number which describes in specific terms, the ability of a material or assembly to transmit heat from outside to inside surfaces. Assemblies with lower U-values transmit less heat than those with higher values. Please see the charts below for each product's specific U-Values:

R-Value

A number which describes in specific terms, the ability of a material or assembly to insulate heat. Assemblies with higher R-values insulate more heat than those with lower values.
1 Ă· (U-Value) = R-Value


Solar Heat Gain Coefficient (SHGC)

A measure of how well a glazed door assembly absorbs or reflects heat from the sun. The lower the coefficient, the better the glazed door is at blocking the sun's heat. Glazed doors in hot or temperate climates should have a low SHGC; south-facing glazed doors in cold climates should have a high SHGC. Please see the charts below for each product's specific Solar Heat Gain Coefficients:

Sound Transmission Class (STC)

A measure representing how much noise is stopped by something. The higher the number the better: the scale is logarithmic, meaning each number is significantly higher than the next, like the Richter Scale for earthquake measurement.

STC Ratings & Reports


Design Pressure (DP)

Design Pressure (DP) ratings are based on a Therma-Tru door systems’ performance in Structural Wind Load. As an example: A DP50 structural performance rating indicates that the door system has passed a structural test pressure of 75 lbs. per. sq. ft which is equal to a 165 mph wind. The Design Pressure ratings for Therma-Tru door systems can be found by reviewing the evaluation reports or installation instructions found in the product approvals:
