Windshield Repair Glossary (Ultra Bond / Industry Terms)

1. Can all windshield cracks be repaired?

Not all cracks are repairable — but most are.

According to the ROLAGS (Repair of Laminated Automotive Glass Standard), cracks up to 14 inches long and chips smaller than 1.25 inches in diameter are typically repairable if they do not reach the windshield edge or obstruct the driver’s line of sight.

Ultra Bond’s advanced long-crack resin systems can safely repair cracks beyond 6 inches, often restoring strength to equal or greater than new glass.

2. What types of windshield damage can be repaired?

The most common repairable damage types include:

• Bullseye breaks
• Star breaks
• Combination breaks
• Short and long cracks
• Stone chips

Each break type requires specific tools, resin viscosity, and curing techniques. Ultra Bond’s training and tools are designed to handle all six standard break categories defined by ROLAGS.

3. How does professional windshield repair work?

Windshield repair involves:

1. Cleaning and inspecting the damage.
2. Removing trapped air using a vacuum or injector system.
3. Injecting repair resin under controlled pressure.
4. Curing the resin with UV light.
5. Polishing and verifying clarity and strength.



Properly executed repairs — especially with tested Ultra Bond resin — can restore 100 % of the original glass strength, meeting pre-loss condition insurance requirements.

4. Is windshield repair as strong as glass replacement?

When performed to ROLAGS and ASTM standards using premium resins, the structural integrity of the glass can equal or exceed that of new laminated glass.


Independent testing (ASTM C158, D790) shows that Ultra Bond’s proprietary resin formulations achieve equal flexural and impact strength to new, unbroken glass.

5. What standards govern windshield repair quality?

Professional repairs follow:

• ANSI/ROLAGS 002–2022 — the U.S. windshield repair standard.
• ASTM mechanical testing protocols — measuring repair strength.
• SAE Z26.1 — safety glazing performance (impact & light transmission).



Meeting these ensures legal compliance, safety, and insurance claim approval.

6. How long does windshield repair take?

A typical chip or short-crack repair takes 20–30 minutes.
Long cracks or multiple breaks may take 45–60 minutes due to extended resin fill and curing time.

7. Is windshield repair covered by insurance?

Yes — in most cases, comprehensive auto insurance covers chip and crack repair with zero deductible.
Because repairs restore glass to pre-loss condition and prevent costly replacement, insurers often prefer repair over replacement.

9. Why is UV curing important in windshield repair?

UV light hardens the injected resin, creating a clear, durable bond.
Inadequate UV curing can cause future delamination, air bubbles, or optical distortion.
Professional UV curing lights deliver consistent exposure for maximum structural restoration.

10. When should a windshield be replaced instead of repaired?

Replacement is necessary if:

• Damage penetrates both glass layers.
• The break is in the driver’s critical view zone.
• The laminated interlayer shows moisture, discoloration, or separation.

If none of these apply, repair is almost always the safer, greener, and more affordable option.

 11. Does windshield repair affect ADAS calibration?

NO — only if the glass is replaced.

Repair preserves the original factory calibration of ADAS (Advanced Driver-Assistance Systems), avoiding costly recalibration and ensuring lane-assist and camera accuracy remain intact.

12. How do I choose a certified windshield repair technician?

Look for technicians trained under



• ANSI/ROLAGS certification programs, or
• Ultra Bond factory training courses, which include long-crack repair and advanced structural bonding.

Certified repair professionals use tested resins, calibrated tools, and adhere to recognized quality protocols.

13. What are the environmental benefits of windshield repair?

Each windshield repair saves:

~ 25 pounds of glass waste from landfills

~ 50 pounds of CO₂ emissions

The cost and energy of replacement manufacturing

Repairing instead of replacing supports sustainability and circular auto glass practices.

14. Can I repair a windshield crack myself?

DIY kits can fix small chips, but professional systems:

• Use industrial-grade injectors and resins
• Ensure vacuum pressure, air removal, and UV curing meet standards
• Are tested for safety under ROLAGS/ANSI

If the crack is longer than 3 inches or involves an edge, professional repair is required.
