01 / Overview

What Is Glass Breakage Cover?

The glass breakage section of an ISR policy provides dedicated cover for the accidental breakage of glass at your commercial premises. While glass damage can sometimes fall under the property damage section, a specific glass breakage extension is designed to pick up accidental breakage events that may not involve an external peril.

For retail businesses, hospitality venues, commercial offices and showrooms, glass is a prominent and expensive feature of the premises. A broken shopfront window not only creates an immediate security risk but also disrupts trade, affects your professional appearance and can be costly to replace - particularly for large, custom or specialty glass panels.

Glass breakage cover is designed to help you replace damaged glass promptly, so there's less disruption to trade, security and presentation while permanent repairs are arranged.

03 / Exclusions

Common Exclusions

Glass breakage cover is designed for accidental and sudden breakage events. The following are commonly excluded:

  • Scratching, chipping or cracking that does not result in full breakage of the glass
  • Breakage occurring during installation, removal or alteration of the glass
  • Damage to glass in buildings that are vacant or unoccupied beyond a specified period
  • Glass in frames that are in a state of disrepair or deterioration
  • Breakage caused by building settlement, expansion or contraction
  • Damage to stock or contents behind or near the broken glass (covered under property damage)
  • Glass breakage at premises undergoing renovation or construction works

It is worth noting that many insurers require you to maintain a schedule of glass items with their dimensions and type. Keeping this schedule up to date helps the claim process move faster if a breakage occurs, because the replacement cost is already agreed.

04 / FAQs

Glass Breakage FAQs

Yes, toughened, laminated, safety and double-glazed glass can all be covered under the glass breakage section. These specialty glass types are typically more expensive to replace than standard plate glass, so it is important to ensure your sum insured reflects the actual replacement cost, including any special manufacturing or supply lead times.
Yes, the reasonable cost of temporarily boarding up or securing an opening after glass breakage is typically covered, which helps keep the premises secure while permanent replacement glass is arranged. The cover usually extends to temporary screening, hoarding or protective measures needed to maintain security, subject to the sub-limit on your policy.
Many ISR policies include cover for the cost of replacing signwriting, lettering, painting, embossing or protective film that was applied to the broken glass. This is an important consideration for retail businesses with branded shopfronts or offices with frosted privacy film, as these add-ons can represent a significant portion of the total replacement cost.
Glass breakage claims are usually subject to a policy excess, which may differ from the main property damage excess. The excess amount varies between insurers and policies. Some policies offer a nil excess on glass breakage claims, while others apply a standard dollar amount. Check your policy schedule or speak with your broker to confirm the excess that applies.
