Does Innovative Structural Glass recommend the use of clear silicones?
A While clear silicones can be used in conjunction with our systems, generally we do not recommend the use of clear silicones for aesthetic reasons. Clear silicones are not truly clear, but are typically translucent. Over time, clear silicone tends to yellow, thus drawing the eye. Silicone, by its nature, also attracts dirt and dust which is highlighted with the use of the clear silicone. When silicone is applied to a typical joint, it is tooled to give it a smooth appearance. It is nearly impossible to apply the silicone to ensure that no air bubbles will encased in the joint from both the tooling process and the product itself as it comes from the factory. These air bubbles are more commonly viewable in clear silicones. Our general recommendation is with highly transparent constructions, select a black silicone since viewing occurs through the glass, not at the joint.
