aerogel technology. A wide number of com-
binations is available for use in façades, separation walls and curtain walls;
the thickness of the systems varies in the 10-50 mm range (Fig. 10.8).
Many daylighting systems with polycarbonate are proposed by TGP
America, Advanced Glazings Ltd (Canada), and Xtralite (UK) (Dowson
et al.
, 2011). Glazing systems with nanogel are also developed by Okalux,
