Glaziers and Asbestos Exposure: Window Putty, Caulking Compounds, and Glazing Materials Created Sustained Mesothelioma Risk (1940-1980)

Executive Summary

Glaziers—skilled tradespeople who install glass in windows, doors, skylights, and storefronts—experienced significant asbestos exposure from the putty, caulking, and sealing compounds essential to their trade from the 1940s through 1980. Window glazing putty contained 5-15% asbestos, caulking compounds contained 5-25% asbestos, and specialty glazing materials contained 3-12% asbestos—fibers that were released during application, removal, and renovation work. Landmark litigation against DAP Inc.—a major caulk and putty manufacturer—established manufacturer liability for asbestos-related diseases in glazing products, with courts allowing multiple mesothelioma lawsuits to proceed. The Italian National Mesothelioma Registry documented the construction sector as a primary exposure source, with glass and window installation representing a documented occupational category. Glaziers now qualify for compensation through more than 60 bankruptcy trusts holding over $30 billion.

Why Did Glaziers Face Asbestos Exposure?

Glaziers encountered asbestos exposure because the products fundamental to their trade—putty, caulking, sealants, and glazing compounds—incorporated asbestos fibers to enhance performance characteristics essential for window installation.

Asbestos improved product performance in multiple ways. Manufacturers added asbestos to glazing products because the mineral fibers provided:

• Enhanced durability: Asbestos prevented cracking and deterioration
• Weather resistance: Fibers improved resistance to moisture and temperature extremes
• Adhesion: Asbestos improved bonding between glass and frames
• Fire resistance: Mineral fibers provided fire-retardant properties
• Workability: Asbestos created smoother application characteristics

Glaziers handled these products daily throughout their careers. The trade required:

• Mixing and kneading putty before application
• Applying glazing compound to window frames
• Tooling and smoothing freshly applied materials
• Scraping and removing old, dried putty during renovation
• Applying caulking around window perimeters
• Handling gaskets and weatherstripping materials

Exposure intensified during renovation work. Removing old glazing putty from windows installed decades earlier released dried, friable asbestos-containing material that had become increasingly hazardous with age.

"Glaziers worked with their hands in direct contact with asbestos-containing putty and caulking every day. They kneaded the material, pressed it into place, smoothed it with tools, and scraped off old material—all without any understanding of the asbestos hazards. The exposure was intimate and sustained over entire careers."

— Rod De Llano, Founding Partner, Danziger & De Llano

What Does the Litigation Evidence Show About Glaziers' Asbestos Exposure?

Significant litigation against manufacturers of glazing products has established the hazards faced by glaziers and confirmed manufacturer liability for asbestos-related diseases.

DAP Inc. Mesothelioma Lawsuits

DAP Inc., a major manufacturer of caulking compounds, putty, and sealants, has faced multiple mesothelioma lawsuits filed by workers exposed to their asbestos-containing products.

Judge Rejects DAP's Dismissal Motion: A court denied DAP's attempt to dismiss a mesothelioma lawsuit, allowing the case to proceed based on evidence of asbestos content in DAP caulking products and the plaintiff's exposure history.

Multiple Lawsuits Filed: DAP has been named in numerous mesothelioma lawsuits filed by glaziers, construction workers, and others who worked with the company's asbestos-containing caulking and putty products. Courts have consistently allowed these cases to proceed to trial or settlement.

Veteran Lung Cancer Case: A New York judge denied DAP's motion to dismiss a veteran's lung cancer claim linked to asbestos exposure from the company's products, further establishing the legal foundation for glazier exposure claims.

Italian National Mesothelioma Registry Data

The Italian National Mesothelioma Registry documented the construction sector as a primary source of occupational asbestos exposure:

• 3,574 mesothelioma cases with "certain" occupational exposure in construction (1993-2018)
• Mean latency: 47.8 years from first exposure to diagnosis
• Mean age at diagnosis: 70.3 years
• Glass installation and finishing trades represented documented categories within construction-related cases

⚠ Latency Period Warning: The 47.8-year average latency period means glaziers exposed during the 1970s are being diagnosed with mesothelioma now in 2026. Workers exposed during the 1960s peak construction era may still develop disease in coming years. If you worked as a glazier before 1980 and experience breathing difficulties or chest pain, seek medical evaluation immediately.

Which Asbestos Products Did Glaziers Encounter?

Glaziers worked with multiple categories of asbestos-containing products. Understanding specific product exposures is critical for identifying responsible manufacturers and applicable bankruptcy trusts.

Window Glazing Putty (5-15% Asbestos)

Product Type	Manufacturers	Asbestos Content	Applications
Traditional glazing putty	DAP, Gibson-Homans	5-15%	Window glass bedding
Metal sash putty	Various manufacturers	8-12%	Steel window frames
Wood sash putty	DAP, others	5-10%	Wood window frames
Face putty	Multiple brands	6-12%	Exterior glazing finish

Glazing putty was the primary material used to secure glass panes in window frames. Glaziers handled this material constantly—mixing it, applying it, tooling it smooth, and removing old dried material.

Caulking Compounds (5-25% Asbestos)

Product Type	Manufacturers	Asbestos Content	Applications
Building caulk	DAP, Tremco, Pecora	5-15%	Window perimeter sealing
Glazing caulk	Various	8-20%	Glass-to-frame sealing
Weatherproofing caulk	3M, others	10-25%	Exterior weather seals
Fire-stop caulk	Multiple	15-25%	Fire-rated assemblies

Caulking compounds were applied around window perimeters to create weather-tight seals. The higher asbestos content in some formulations reflected the need for enhanced durability and fire resistance.

Glazing Compounds and Sealants (3-12% Asbestos)

Product Type	Asbestos Content	Applications
Butyl glazing compound	3-8%	Commercial window systems
Polysulfide sealant	5-12%	Curtain wall systems
Structural glazing sealant	4-10%	High-rise window installation
Setting blocks	Variable	Glass positioning in frames

Gaskets and Weatherstripping (40-90% Asbestos)

Product Type	Asbestos Content	Applications
Rubber gaskets	40-60%	Window frame seals
Compression gaskets	50-80%	Commercial storefront systems
Fiber gaskets	70-90%	Industrial window assemblies
Weatherstripping	30-50%	Door and window seals

Gasket materials contained some of the highest asbestos concentrations of any products glaziers encountered. These materials were cut, fitted, and compressed during installation.

"DAP was one of the most widely used brands among glaziers for decades. The company's caulking and putty products were found on nearly every construction site. When we investigate a glazier's case, DAP is almost always among the products identified—and that creates a clear pathway to compensation."

— Paul Danziger, Founding Partner, Danziger & De Llano

Which Manufacturers Produced Asbestos-Containing Glazing Products?

Several manufacturers produced glazing products containing asbestos. Understanding these companies helps identify applicable bankruptcy trusts and potential defendants.

How Did Glaziers Get Exposed to Asbestos?

Glaziers encountered asbestos through multiple exposure mechanisms during typical work activities.

Mixing and Kneading Putty

Putty preparation generated direct exposure. Before application, glaziers worked putty by hand to achieve proper consistency:

• Removing putty from containers released surface dust
• Kneading and rolling putty created friction that released fibers
• Adding linseed oil or other modifiers disturbed dried surface material
• Extended handling created cumulative fiber exposure

Applying Glazing Compounds

The application process required intimate contact with asbestos-containing materials:

• Pressing putty into window frames released fibers into the breathing zone
• Tooling and smoothing created friction that released embedded fibers
• Working in confined spaces (window openings) concentrated exposure
• Repetitive application throughout workdays accumulated exposure

Removing Old Putty and Caulking

Renovation work created the highest exposures. Removing aged glazing materials required:

• Scraping dried, brittle putty that had become friable with age
• Chiseling out hardened material that crumbled upon disturbance
• Sanding window frames to remove residual material
• Wire brushing frames to prepare surfaces for new glazing

Aged asbestos-containing putty releases fibers more readily than fresh material because weathering and oxidation break down the binder, leaving asbestos fibers more loosely bound.

Cutting and Fitting Gaskets

Glaziers cut gasket materials to size for window and door installations:

• Cutting compressed asbestos gaskets released fiber-laden dust
• Fitting and compressing gaskets during installation released additional fibers
• Trimming excess material after installation created exposure

Caulking Application

Applying caulking around window perimeters exposed glaziers to asbestos compounds:

• Cutting caulk tubes released surface fibers
• Tooling fresh caulk created friction exposure
• Cleaning tools spread asbestos-contaminated material

ℹ Did You Know: Glaziers often worked without gloves because direct hand contact was necessary to properly work putty and achieve smooth finishes. This meant asbestos fibers contacted bare skin throughout each workday, and fibers could be ingested when workers ate or smoked without washing their hands.

Are Glaziers Still at Risk from Asbestos Today?

While asbestos-containing glazing products are no longer manufactured, legacy materials in existing buildings create ongoing exposure risk for glaziers performing renovation, repair, and replacement work.

Legacy Asbestos in Existing Buildings

Asbestos-containing putty, caulking, and gaskets remain in place in:

• Residential homes: Original windows in pre-1980 housing
• Commercial buildings: Office buildings, retail spaces with original glazing
• Industrial facilities: Factories, warehouses with steel-framed windows
• Institutional buildings: Schools, hospitals, government buildings
• Historic structures: Buildings where original materials have been preserved

High-Risk Current Activities

• Window replacement: Removing original glazing from pre-1980 windows
• Restoration work: Preserving historic windows requires putty removal
• Weatherization projects: Removing and replacing old caulking
• Building renovation: Disturbing original window assemblies
• Demolition: Breaking apart structures with original glazing intact

OSHA Regulations for Current Workers

OSHA's Construction Industry Asbestos Standard (29 CFR 1926.1101) establishes requirements for glaziers encountering asbestos materials:

• Permissible Exposure Limit: 0.1 f/cc (8-hour TWA)
• Class II Work: Removal of asbestos-containing caulking, putty, and gaskets
• Required Controls: Wet methods, HEPA vacuums, containment as appropriate
• Respiratory Protection: Required when exposures may exceed PEL
• Training: Required before working with asbestos-containing materials

⛔ Critical Safety Warning: Never remove glazing putty, caulking, or gaskets from windows installed before 1980 without professional asbestos testing. Window replacement in older buildings frequently disturbs asbestos-containing materials. Dry scraping of old putty can release dangerous fiber concentrations. Contact a licensed asbestos inspector before any window renovation project.

What Compensation Is Available for Glaziers with Mesothelioma?

Glaziers diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may recover substantial compensation through multiple sources.

Asbestos Bankruptcy Trust Funds

More than 60 active asbestos bankruptcy trusts hold over $30 billion available for qualified claimants. Glaziers typically qualify for claims against multiple trusts based on exposure to products from various manufacturers.

Key trusts for glaziers include:

Trust Fund	Products Covered	Typical Payment Range
Garlock Sealing Technologies Trust	Gaskets, packing, sealing	$4,000 - $175,000+

National Gypsum Trust	Building materials	$2,500 - $100,000+

Trust fund claims do not reduce your ability to pursue lawsuits, workers' compensation, or other compensation sources—these can be pursued simultaneously.

Personal Injury Lawsuits

Glaziers may file lawsuits against companies that manufactured, distributed, or sold asbestos-containing products without adequate warnings.

Key defendants in glazier cases:

• DAP Inc.: Multiple courts have allowed mesothelioma cases to proceed
• 3M: Sealant and adhesive products
• Active gasket manufacturers: Crown Cork & Seal, Tremco, others

Average mesothelioma settlements for construction workers range from $1 million to $1.4 million.

Wrongful Death Claims

Family members of glaziers who died from mesothelioma may file wrongful death claims to recover:

• Medical expenses incurred before death
• Lost income and future earnings
• Loss of consortium and companionship
• Pain and suffering damages
• Funeral and burial expenses

"The DAP litigation has been particularly important for glaziers because it establishes clear manufacturer liability for asbestos in caulking and putty products. When courts allow these cases to proceed, it validates the exposure claims of glaziers who worked with these products for years."

— Rod De Llano, Founding Partner, Danziger & De Llano
