Pilkington Profilit OW is an addition to Technical Glass Products’s low-iron, translucent, linear channel glass systems. It can increase visible light transmission up to 90% in uninsulated channels. It consists of self-supporting, low-iron-oxide cast-glass channels in an extruded metal perimeter frame. The glass comes in lengths up to 23' for both vertical and horizontal applications, and is available in three textures: standard cast, a patterned surface; wave, a large wave texture; and macro, a netted screen texture. It is available with a low-E coating for improved thermal performance and can also be filled with Nanogel aerogel, a lightweight insulation material. tgpamerica.com; 800.426.0279.
