Safety first: proper tempering protects shower industry partners and customers

This exclusive SGCC certification number identifies each qualifying Cardinal safety glazing product and plant-specific origin, providing assurance of proper SGCC safety compliance.

LOUISVILLE, KENTUCKY, OCTOBER 2019 — Ensuring that shower glass is properly tempered is an essential responsibility of shower glass manufacturers, and a key step in protecting everyone involved in the design, sale and installation of shower enclosures.  It’s also a critical product feature that protects consumers in the event of potential broken glass incidents in the shower.

We asked Diego Rodriguez, Vice President of Sales and Marketing of HMI Cardinal, to talk about the importance of safety certification for shower glass.

Insist on proper certification from your shower glass manufacturer.
When it comes to safety, Rodriguez notes, “not all shower glass is created equal.” Proper tempering results in glass that is less likely to cause injury if broken. That is because tempered glass crumbles into small granular chunks when broken, instead of splintering into jagged shards as plate glass does. The granular chunks are less likely to cause injury.

“The best way for industry professionals to protect themselves and their customers is to insist on proper certification from the shower glass manufacturer,” Rodriguez advises. “This means choosing a manufacturer that is certified by the Safety Glazing Certification Council.”

Safety Glazing Certification Council (SGCC) compliance.
The Safety Glazing Certification Council (SGCC) is an independent, non-profit organization dedicated to public safety, and the institution of glazing industry safety standards. SGCC provides certification that a manufacturer’s glazing materials, if broken, will reduce the risk of injury or death. Certified SGCC manufacturers will adhere to SGCC certification requirements, assuring that glass from each shift is independently tested to ensure proper tempering specifications, and that an approved quality assurance program is maintained for safety glazing fabrication.

Tempered glass breaks down into smaller pieces, with duller edges than standard glass, making it a much safer shower alternative.

The best advice: “don’t take chances.”
When asked for the best advice he can give industry partners in the shower enclosure market, Rodriguez says it is, “don’t take chances.”

In potential legal disputes involving a broken glass panel, SGCC certification can be an important factor in the protection of the manufacturer, architect, installer, and/or building owner and others. In such cases, SGCC certification can provide documentation that the glass was tempered according to exacting standards.

The conclusion is simple: insist on SGCC certified glass from a reputable shower enclosure manufacturer.  To ensure you’re getting SGCC-certified glass from a reputable shower enclosure manufacturer, look for the SGCC seal, which is normally located on the lower right-hand side of the shower door.
