Car Trivia of the Day: The Importance of Your Windshield

Posted in Car Accessories, Car Tech, Crash Testing, Guide, Materials by Vito Rispo | September 9th, 2008 | 4 Responses |

Structural Integrity – The windshield is an important part of a vehicle’s energy management systems, which directs crash energy around the occupant compartment. If the windshield is improperly installed, the vehicle may crumple differently than the manufacturer intended, which may jeopardize occupants.

Rollover Strength – In a rollover accident, the windshield provides strength by helping to keep the roof from crushing in on any vehicle occupants. The windshield can supply anywhere from 30% to 50% of the vehicle’s rollover strength.

Airbag retention – On impact the windshield acts as a brace to support the passenger side airbag. If the windshield separates, the airbag does not have a constrained space, and it is not effective in protecting the occupant.

    Mine leaks around the edges because it cracked, causing it to expand and retract irregularly and break the seal. Unfortunately the previous owner slathered loads of black tar over the chrome to stop the leak that could have been stopped by simply getting a new windshield.

    All of this is possible because of the urethane adhesive that has been used for the last few decades. Many times inexperienced or unqualified installers will jeopardize your safety by using incorrect materials or methods while installing a replacement windshield as Vito points out. Avoid “street mechanic” or DIY windshield installations.
