The thermal conductivity of metal frames allows for hot or cold temperatures from the exterior of a building to transfer to the interior. Many design professionals are turning to thermal break frames to meet regional codes or the energy efficiency requirements of building owners.
Thermal break frames have a separator material that is highly resistant to thermal conductivity. This significantly lowers the U-value and reduces energy costs in areas with hot or cold weather. Manufacturers generally test to SDI-113 for the thermal transmittance of steel door and frame assemblies.
The SDI Certified manufacturers below make thermally broken door frames, transoms, sidelights, and borrowed lights that meet our standards.
