Glass Coverage (Plate Glass)
Definition
Glass coverage pays to replace broken windows, storefront glass, glass doors and similar building glass. Many commercial property forms now cover building glass as part of the building, but deductibles, limits and vacancy rules can make a separate glass endorsement worth considering for storefront-heavy properties.
In Plain English
Shopping centers, convenience stores and office buildings often have large panes that break from vandalism, burglary, wind or accidents. Under the Causes of Loss – Special Form, glass is generally covered as part of the building, subject to the deductible and any limitations.
Some policies limit glass breakage per pane or per occurrence. Under many vacancy clauses, building glass breakage isn't covered once a building has been vacant more than 60 consecutive days.
Lease terms often decide whether the landlord or the tenant replaces broken storefront glass. When a high deductible makes small glass claims uncollectible, a separate glass endorsement with its own lower deductible may help. Many policies handle signs separately.

Example
Hypothetical and simplified: A burglar smashes a $4,000 storefront window at a strip center. With a $10,000 property deductible, the owner pays the full cost. A separate glass endorsement with a $250 deductible may pay most of it.
What to Watch For
- Check your leases to see who replaces storefront glass.
- Ask whether glass has its own deductible or limit.
- Check the vacancy rules if a unit sits empty.
- Board up broken glass quickly to prevent further damage or theft.
