Is there any performance difference between the thermal insulation materials (TIMs) available for channel glass walls?
There aren’t any significant thermal performance difference between Wacotech & Okapane thermal insulation materials (TIMs) for channel glass walls. There is also a third TIM for channel glass walls, called Nanogel or Lumira. It consists of polycarbonate tubes filled with aerogel pellets.
All three thermal insulation materials have essentially the same U-Value, SHGC, and light transmission performance. However, Nanogel can be costly, may be susceptible to settling, and does not completely fill the channel glass cavity the way Wacotech and Okapane do. Therefore, the actual insulation value of Nanogel is a little less than its advertised performance.
