Shields by Sigco™ - Spandrel Glass

SIGCO manufactures spandrel glass – glass that has been rendered opaque to shield building material from view – with a new state-of-the-art roll coater, drying oven and cooler.  The process that we use to manufacture our spandrel glass produces a superior product when compared to material that has been hand sprayed or curtain coated.

SIGCO offers eight standard colors.  Custom color spandrel is also available, as are applications on low-iron, tinted or pyrolytic reflective glass substrates.  Our spandrel glass is available in monolithic lites or sealed insulating glass units.  It should only be glazed against a dark background, such as above a ceiling or below a knee-wall and should not be used in transoms, partitions or other exposed applications.

SIGCO offers spandrel glass manufactured using either ceramic frit or OPACI-COAT 300.  In the ceramic frit process, lead free colored ceramic frit is applied to annealed glass.  This glass must then be heat strengthened.  If it is being used in a safety glazing application, it must be fully tempered.  This heat treatment process permanently fuses the frit to the glass.

Ceramic frit spandrel should only be used in a four-side captured glazing system.  It should not be used in butt glazed, structural glazed or exposed edge glazing applications.

In the OPACI-COAT 300 process, a one part water based silicone component is often applied to glass that has already been heat treated.  Upon the evaporation of the water, the coating cures to a tack-free silicone film.

Because OPACI-COAT 300 is applied without heat at the final stage of the fabrication process, it can be used with equal effectiveness on annealed, heat strengthened or fully tempered products.  Please note that heat strengthening is required on all exterior applications, and a fully tempered product must be used in safety glazing applications.

When required and specified, OPACI-COAT 300 can be applied at a thickness that will satisfy the criteria for fallout protections without taping or scrim films.  With edge deletion and shop drawing review, structural glazing may be possible.
