Sky Tunnel Rigid Tube Comparison
Reflectivity-Over-Time-Test
MIRO - SILVER® vs. Multi-layer Polymeric Film
Comparison of sustained reflectivity after 150 hours UV-C Exposure.
Sky Tunnel™ utilizes Alanod Miro Silver® when producing the Rigid98 used in its Rigid Tube Kits.
You can see from the graphic above, 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®.
Reflector Material under different angles
Comparison between MIRO - SILVER® and Multi-layer Polymeric Film (MPF)
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.
