Laminated Glass: A glass failure analysis expert witness was engaged to inspect hurricane window defects. These windows were sold to meet the Miami Dade/State of FloridaBuilding Code Requirements for hurricane resistance, and during development of the process, it appears as if these requirements were met. However, the laminating plastic in these windows interacted with the heat and humidity in South Florida. It appears that the laminated windows have a lamination plastic that dissolves and loses adhesion to the glass (please see attached photos). After deterioration, these windows are no longer acceptable visually. In addition, it is certain that they will not pass the required code tests.
Good afternoon Mr Read,
In search of some more fire-power, I came across your excellent website. I am a home inspector (and certified builder) here in south Florida. I periodically notice delamination on hurricane impact rated windows. Typically, I call them out as needing replacing. However (the latest one) the seller of the property tried saying its a “cosmetic defect”. I told him (at a minimum) it needs review by a licensed engineer. Do you happen to have any more literature on the testing of delaminated hurricane windows that I can forward to the other party? If not, can you direct me to someone that does? Your help would be greatly appreciated!
Keep up the good work!
In my opinion de laminated windows are compromised and need to be replaced. They will not withstand the required impact tests.
