TESTING OF GLASS LAMINATES FOR EDGE STABILITY

Laminated glass is a high performance construction material comprised of glass and polymer interlayer which is bonded together under a heat and pressure process. Laminated glass is typically subjected to performance testing meant to evaluate the capability of the material in its resistance to damage or attack. Edge delamination typically results from damage or attack originating at the edge of laminated glass where the interlayer is exposed. Edge delamination affects the aesthetics of laminated glass and may be described as a material characteristic known as edge stability.

Determination of the edge stability of a laminated glass construction is complex but can be examined through various methods of test. Exposure of the laminate to moisture and chemicals, specifically at the edge, is the basis of various test protocols that result in the development of edge stability ratings. This paper presents exposure protocols including natural weathering, sealants, salt fog and immersion. Rating processes and results will be discussed for various interlayers. The attending will be familiar with the test scope, purpose and results interpretation of the included testing. This information allows the specifier to make an informed choice in selecting installation methods, system design and laminated glass products.
