Comparison between MIRO-SILVER® and Multi-layer Polymeric Film (MPF)
Reflectivity-Over-Time Test
|
Sky Tunnel™ utilizes Alanod Miro Silver® when producing the Rigid98 used in its Rigid Tube Kits. You can see from the graphic, that whilst some other daylighting products using a Multi-layer Polymeric Film in their Rigid Tube have a higher initial Total Reflection, after just 40 hours of exposure to UV-C the reflection drops below that of the Miro Silver®. |

  Advantage for MIRO-SILVER® (0-45°) Same reflectivity for both products
|
Light Pipes such as Sky Tunnel™ which utilize MIRO – SILVER® will transmit much more light between 0 and 45 degrees when usable light is really needed.
