Insulite specializes in crafting ceramic spandrel glass, specifically designed for application in non-vision glass areas of curtain wall and window constructions. The purpose of spandrel glass is to conceal the unattractive building materials that might lie within a window opening, ensuring they remain hidden from the building's exterior view. Common instances include regions above ceilings and floor lines in curtain walls or knee walls that connect to the window framing. By using spandrel glass, the overall aesthetic appeal of the building is enhanced, creating a seamless and visually pleasing exterior appearance.

Insulite strongly advises against the use of spandrel glass without a consistent opaque background. It is essential to ensure that areas such as transoms, sidelites, or any location lacking backup material are avoided for this purpose. Without a uniform opaque background, the spandrel glass may not achieve its intended functionality, compromising the overall appearance and design integrity of the building. To maintain a seamless and aesthetically pleasing outcome, it is crucial to adhere to this recommendation and utilize spandrel glass only in conjunction with an appropriate and consistent opaque background.

Insulspan ceramic enamel is a composite of finely-ground glass particles blended with a medium and pigment, and it is skillfully applied to the glass surface using the roll-coating process. Once applied, the enamel undergoes firing to establish a durable and lasting coating. For this purpose, Insulite employs Ferro enamel, which is widely recognized and accepted in the industry for its lead-free composition.

The versatility of Insulspan ceramic spandrel allows it to be effectively applied to various glass types. It can be used on the #2 surface of monolithic clear, tinted, or pyrolytic reflective glass. Additionally, it is suitable for application on the #2, #3, or #4 surface of insulating glass. This flexibility ensures that the ceramic spandrel can be utilized in a wide range of construction scenarios while maintaining its high-quality performance and appearance.

viewing only.

Insulspan is not intended for use in vision wall areas. Instead, Insulspan ceramic frit spandrel should be glazed in non-vision areas, placed against a consistent opaque background. It should not be utilized in situations where it may be visible with natural or artificial light from the opposite side, such as transoms, partitions, or any scenario where a uniform opaque background cannot be achieved.

Insulspan can be utilized in structurally glazed applications, but it's important to note that a clear leading edge of 0" to 1/8" might be visible. Additionally, please be aware that all edges are seamed and not polished in this context.

Insulspan Inspection Guidelines

  • When observing spandrel glass from a 15 ft. distance under natural daylight conditions, it is important to note that color and reflectance might exhibit variations compared to when viewed against a uniform, opaque background. It is essential to understand that such variations do not indicate a defect in the product.

  • When examining spandrel glass under comparable conditions, the presence of reflected pinholes and scratches should not be regarded as defects, provided they are not conspicuous or obstructive. In such instances, these minor imperfections can be considered acceptable and do not compromise the overall quality of the glass.
