Amarr is a participant in the DASMA Thermal Performance Verification Program. All Amarr insulated doors have been tested from a certified, third-party lab for legitimate thermal performance U-factor rating. Amarr verified thermal performance ratings by commercial product model are shown below:
DASMA Thermal Performance Verification Program
The DASMA Thermal Performance Verification Program (TPVP) was launched to establish U-factor as the industry standard for thermal performance rating for a sectional door. All U-factor thermal performance ratings by participating sectional door manufacturers have been verified using certified third-party testing and inspection.
Identifying DASMA Verified Thermal Performance
Look for the TPVP badge or icon, which can only appear with models that participate in the program. Only participating manufacturers have verification program badge in marketing materials. The badge and/or icon denotes legitimate thermal performance rating (validated by third-party testing).
How are U-factor and R-value different?
The building and construction industry use both R-value and U-factor to measure thermal performance. These thermal performance ratings are not mathematically associated, as the testing methods are completely different.
U-factor
- U-factor is a measure of the rate of heat loss through a material.
- The U-factor number is determined based on an actual test of an entire door assembly.
- The lower the value the less heat transfer through a material.
- Lower is better!
R-value
- R-value is the measure of material thermal resistance to heat flow.
- The R-value number is calculated based on the thickness of the insulation and its chemical properties.
- The higher the value the more the material resists heat transfer
- Higher is better!
