DASMA Thermal Performance
Verification Program
What is the DASMA Thermal Performance Verification Program?
The DASMA Thermal Performance Verification (TPV) Program is a voluntary program to certify and verify the thermal performance ratings of scope sectional door products using third-party testing and inspection. The program represents a shift in how sectional garage door thermal performance is rated, from traditional R-value to more accurate and relevant U-factor. U-factor ratings are tested whereas R-value is calculated. U-factor tests the whole installed assembly and R-value is calculated for only a portion of section insulation.
What is U-factor?
- U-factor is a measurement of heat transfer or flow through, in our case, a garage door.
- Higher heat transfer is generally "bad" as it results in greater loss of energy, either from heated or cooled air.
- A lower U-factor, which indicates less heat transfer, is better than a higher U-factor.
How does the TPV program work?
Member companies of DASMA that manufacture sectional doors voluntarily agree to participate in the program. Third-party tests are conducted at labs according to ANSI/DASMA 105. Tests and certifications are submitted to the program administrator, ICC-ES. Participants agree to abide by all program rules and requirements.
How can I find the products included in this program?
You can look for the program badge, label, or icon, which can only appear with models that participate in the program.
