Plate glass insurance

Plate glass insurance is a type of insurance that protects small businesses against financial losses if any large panes of glass are accidentally or maliciously broken.

What is plate glass insurance?

Plate glass insurance is a specialized form of commercial property insurance that covers the substantial costs to repair or replace large panes of glass that are broken by accident, vandalism, or theft.

This coverage is often required by landlords to sign a commercial lease, particularly for new building space with large front windows.

What does a plate glass insurance policy cover?

Plate glass insurance covers repair and replacement costs if any large windows, glass storefronts, or glass doors at your business are damaged or broken. Because large glass panes can be very expensive to replace, this type of insurance offers peace of mind to policyholders who would otherwise have to pay for damage out of pocket.

Covered expenses typically include:

  • Accidental breakage due to unexpected impact
  • Glass damage from vandalism and break-ins
  • Temporary boarding and security costs
  • Materials and installation fees
  • Decorative lettering, graphics, or signage applied to the glass

Is plate glass covered under property insurance?

Plate glass coverage is typically added to a commercial property insurance policy to cover large glass panes in display windows, doors, and other parts of your business property. If you rent an office with a lot of windows or a retail space with a glass storefront, your landlord will likely require you to have this coverage.

It can also be added to a business owner’s policy (BOP) as an endorsement. A BOP bundles general liability and commercial property insurance to protect your business against lawsuits and damages in one convenient package.

How much does plate glass insurance cost?

What is typically excluded from plate glass coverage?

Although plate glass insurance provides important coverage for small businesses, there are certain limitations. Some common exclusions include damage or breakage due to:

  • Earthquakes, storms, and other natural disasters
  • Improper installation
  • Fire, explosions, or severe heat
  • Acts of war, rebellion, or nuclear accidents
  • Minor scratches or chipping
  • Property damage caused by broken glass

What is the difference between plate glass and glass insurance?

Plate glass insurance is a type of specialty business insurance that protects against accidental damage or breakage of large, expensive glass panes in storefronts, windows, and doors.

Glass insurance, also called comprehensive glass insurance, covers accidental and intentional damage to a broader range of items, such as:

  • Windows and doors
  • Display cases
  • Signs and partitions
  • Windshields and side windows in business vehicles

If your business owns or leases a space with a substantial amount of glass externally and internally, a comprehensive glass policy is recommended, since plate glass insurance only protects panes of glass.
