Interactive coverage guide

Build a coverage stack around how the business actually operates.

Start with the preselected industry or trade, then adjust the operational questions. The commonly considered stack updates live. Keep the coverages you want GIB to evaluate, remove ones you do not want included in your quote request, and add other available lines before continuing.

Common Starting Coverages

General LiabilityThird-party injury and property damage

What it is

General Liability commonly addresses covered third-party bodily injury, property damage and certain personal or advertising injury claims, subject to the policy.

Why businesses like yours commonly carry it

Businesses commonly use it as a starting liability policy and to satisfy customer, landlord or contract requirements.

Possible coverage gap

General Liability is not intended to replace policies for employee injuries, business vehicles, owned property, cyber events or professional errors.

Business Owners Policy / Commercial PackageLiability and property components evaluated together

What it is

A Business Owners Policy commonly combines liability and property coverages for eligible businesses. A Commercial Package Policy may combine multiple commercial coverage parts depending on the account and carrier.

Why businesses like yours commonly carry it

Businesses with premises, contents, inventory or other property exposures may ask GIB to evaluate whether liability and property components can be packaged where appropriate.

Possible coverage gap

Eligibility, included coverages and package structure vary by carrier. Commercial Property may also be written separately rather than as part of a package.

Commonly Added Based on Operations

Commercial AutoBusiness vehicles, drivers and physical damage

What it is

Commercial Auto may address liability arising from covered business vehicles and, when selected, physical damage and other vehicle-related coverages.

Why businesses like yours commonly carry it

Businesses that own or regularly use vehicles may need a policy structured around business use, drivers and vehicle schedules.

Possible coverage gap

Personal auto policies may restrict or exclude business use, and General Liability is generally not a substitute for auto liability.

Cyber Liability & Data BreachCyber events, data and system interruption

What it is

Cyber insurance may address certain first-party and third-party losses from covered data breaches, cyberattacks, ransomware and system interruption, depending on the policy.

Why businesses like yours commonly carry it

Suppliers invoice contractors constantly and are among the businesses most often impersonated in payment-change fraud.

Possible coverage gap

General Liability generally should not be assumed to address data breach response, ransomware or network interruption.

Exposure-Dependent Coverages

Equipment BreakdownMechanical, electrical and pressure-system breakdown

What it is

Equipment Breakdown may address certain sudden mechanical, electrical or pressure-system breakdown losses, subject to the policy.

Why businesses like yours commonly carry it

Businesses dependent on refrigeration, production, HVAC, electrical or other critical equipment commonly consider it.

Possible coverage gap

Standard property forms may not address every internal mechanical or electrical breakdown.

Learn more about Equipment Breakdown
Commercial Crime / FidelityEmployee theft and certain fraud losses

What it is

Commercial Crime may address certain covered theft, fraud and funds-transfer losses, depending on the selected insuring agreements.

Why businesses like yours commonly carry it

Businesses handling money, inventory, payments or account access commonly consider crime coverage.

Possible coverage gap

Property and cyber policies do not necessarily cover every employee theft or social-engineering loss.

Learn more about Commercial Crime / Fidelity
Umbrella / Excess LiabilityAdditional limits above scheduled liability policies

What it is

Umbrella or Excess Liability may provide additional limits above identified underlying liability policies, subject to its own terms and exclusions.

Why businesses like yours commonly carry it

Businesses with larger contracts, vehicles, public exposure or higher severity potential commonly consider additional limits.

Possible coverage gap

An umbrella does not automatically broaden every exclusion or sit over every policy unless the issued terms say it does.

Middle-Market Account Profile

For larger glass suppliers, underwriting should separate wholesale distribution, cutting, tempering, laminating, insulating-glass fabrication and field glazing. Maximum glass values in transit, rack systems, crane/rigging use and long-lead custom architectural units should be quantified.

Coverage Priorities for This Niche

Fragile-property transit coverage and property valuation are as important as products liability. Fabrication adds machinery/equipment-breakdown exposure, while installation introduces contractor GL and completed operations. Excess limits should reflect the potential severity of building-envelope and bodily-injury claims.

Underwriting Questions Before Marketing the Account

Questions worth reviewing before marketing or binding this account:

Does the company fabricate or only distribute glass?
What is the largest single custom glass shipment?
Are cranes or specialized rigging used?
What percentage of revenue includes glazing installation?
How are breakage and seal-failure claims tracked?

Coverage Gaps Worth Checking

Fragile-property coverage should be reviewed for breakage during loading, transit, rigging and temporary storage. If the company fabricates insulated units or tempers glass, equipment breakdown and manufacturing/product exposure become more important. If it installs, the completed-operations tail can extend for years after the project.

What a Strong Submission Looks Like

Provide revenue split by distribution/fabrication/installation, maximum glass values, largest architectural projects, delivery/rigging methods, fabrication machinery, claims and quality-control processes. Photos of racks, storage, handling equipment and shop controls help distinguish a sophisticated operation from a commodity glass reseller.

Contract and Installation Boundaries

Glass businesses often move between supplier, fabricator and subcontractor roles on different projects. The insurance program should follow those changes. A company that sometimes performs field glazing, shop drawings or engineered attachment systems may need contractor and professional coverage that a pure distributor would not. For high-value curtain wall or specialty glass, the broker should also review maximum transit and staging values and the cost of expedited replacement after breakage. Suppliers that sell finished windows and doors rather than cut glass are covered on window and door supplier insurance.

Frequently asked questions

8 questions — start typing to filter

Is glass breakage in transit an auto claim?

Usually the vehicle and cargo are different exposures.

Does fabrication change liability?

Yes — a supplier that fabricates or tempers glass takes on manufacturing-style products liability that a pure distributor of finished units doesn't carry.

Are seal failures products claims?

They can be — an insulated glass unit's seal failure that shows up years after installation is a classic long-tail products liability scenario.

Does installation require contractor coverage?

Yes — a supplier that also installs glass and glazing takes on the same completed-operations exposure as any glazing contractor, on top of its products liability as a supplier.

Are glass racks part of insured values?

They should be addressed specifically — A-frame and glass racks represent real, often underinsured equipment value that a generic property schedule can miss.

Do custom units create BI exposure?

Long replacement times can matter — a custom-fabricated glass unit damaged or lost in transit may take months to remake, extending the business-income exposure well past a standard property claim.

Does high-rise glazing carry different exposure than residential?

Yes — high-rise curtain-wall and glazing work carries materially higher severity if a unit fails after installation, given the height and the difficulty of remediation.

Are spontaneous glass breakage claims treated as a products loss?

Usually they are approached that way, though it depends on where the glass was when it broke and on what the investigation finds. Nickel sulfide inclusions in tempered glass are the classic cause: a microscopic inclusion expands over time and the pane fails with no impact, sometimes years after installation. Where the supplier sold the unit, a products liability claim against the chain of distribution is the ordinary route, and heat-soak testing records are commonly the first thing requested. Where the glass is still the supplier's own stock, it is a property question instead. Carriers treat the two differently, and the policy as issued decides which grant responds.
