What is a TDI rated window or patio door?
The Texas Department of Insurance (TDI) evaluates windows and patio doors for compliance with the wind loads specified in the International Residential Code (IRC) and the International Building Code (IBC). A TDI product evaluation is not an endorsement of the product or a recommendation that the product be used. Their product evaluation is intended for use by those individuals who are following the design and load criteria in chapter 3 of the IRC and section 1609 of the IBC, considering that they install product in accordance with the manufacturer’s installation instructions.
