Laminated Glass

Laminated glass is manufactured in accordance with EN 14449 [1], and associated standards, and generates a material comprising of glass and polymer interlayers. Typically laminated glasses, including the majority of the SGG STADIP range, will comprise 2 plies of glass with a polyvinyl butyral (PVB) interlayer.

Performance Benefits

Laminated glasses can offer significant performance benefits over non-laminated glass.

Safety & Security

Laminates, when appropriately certified to EN 12600 [2], are safety glasses, allowing their use in critical locations where human impact is a risk. They also offer security performance when certified to EN 356 [3], by withstanding penetration of the glass even when both plies are broken.

Acoustics

SGG STADIP SILENCE uses a specially designed interlayer to reduce noise transmission through the glass. This can offer a significant performance improvement over non-laminated glass of the same thickness. Some example data is shown below;
