There aren’t any significant thermal performance differences between different thermal insulation materials (TIMs) for channel glass walls. All thermal insulation materials typically used with these applications have essentially the same U-Value, SHGC, and light transmission performance. However, Nanogel / Lumira can be costly, may be susceptible to settling, and does not completely fill the channel glass cavity the way Okapane does. Therefore, the actual insulation value of Nanogel is a little less than its advertised performance.

Nanogel consists of polycarbonate tubes filled with aerogel pellets. Okapane consists of miniature acrylic tubes covered by translucent fiberglass sheeting.
