Is there any performance difference between the thermal insulation materials (TIMs) available for channel glass walls?
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.
