General
- Is there a fee for having building products evaluated by the Texas Department of Insurance? There is no fee for having building products evaluated by the Texas Department of Insurance.
- Why doesn't the Texas Department of Insurance rely on products that have been evaluated by the ICC evaluation service, the Florida Product Approval System, or by Dade County, FL rather than developing their own reports?
There are several reasons. First, not all of the building products that have been evaluated by the Texas Department of Insurance have also been evaluated by the ICC evaluation service, the Florida Product Approval System, or by Dade County, Florida. If we relied exclusively on products that have been evaluated by these organizations, then the availability of certain products may be limited. Second, windows, glass doors, and skylights, that have been evaluated by Dade County, FL. are not tested and labeled as required in Section R613.4 and R613.7.1 of the International Residential Code (IRC) and Section 1714.5.1 of the International Building Code (IBC) for windows and glass doors and in Sections R308.6.10 and R308.6.12.1 of the Texas Revisions to the IRC, Section 2405.5 of the IBC, and in Section 2405.7.1 of the Texas Revisions to the IBC for skylights.
- Will the Texas Department of Insurance evaluate products that have been evaluated by the ICC evaluation service, by the Florida Product Approval System, or by Dade County, FL?
The Texas Department of Insurance will review product information for many products that have already been evaluated by other organizations. Before developing an evaluation report, the TDI will first determine if the product meets the building specifications that have been adopted by the TDI. The TDI will not be able to evaluate a product that has been tested to the Dade County, FL criteria if it is not able to comply with Sections R613.4 and R613.7.1 of the IRC or Section 1714.5.1 of the IBC for windows and glass doors or Sections R308.618 and R308.6.12.1 of the Texas Revisions to the IRC, Section 2405.5 of the IBC, and Section 2405.7.1 of the Texas Revisions to the IBC for Skylights.
- Are Texas licensed professional engineers who are appointed by the Texas Department of Insurance (TDI) as qualified inspectors required to use product evaluation reports developed by the TDI on structures they are certifying?
No. The engineer appointed as a qualified inspector may use information, such as test reports and design drawings provided by the product manufacturer or code evaluation reports, to determine if a product meets the required adopted building specifications and the design requirements for the structure.
- What design pressure should I test my product to resist?
Please refer to Tables R301.2(2) and R301.2(3) of the IRC or ASCE 7-05. Products tested in accordance with ASTM E 330-02 must be tested to 1.5 times the design pressure.
- In areas where windborne debris protection is required, are exterior wall coverings, such as vinyl siding, required to be tested for windborne debris resistance?
No. Windborne debris protection is only required for exterior opening products such as windows, exterior doors, garage doors, skylights. Please refer to the Texas Revisions for specific windborne debris requirements.
- Are windows, doors, garage doors, and skylights required to be windborne debris resistant in the Inland II zone?
No. In the Inland II zone, there are no requirements for windborne debris. Please refer to the Texas Revisions for specific windborne debris requirements.
- Are windows, doors, garage doors, and skylights required to be windborne debris resistant in the Inland I zone?
In the Inland I zone, on all new construction, additions, renovations, and repairs, all glazed openings are required to be protected from windborne debris. This means that windows, skylights, doors with glazing and garage doors with glazing must be either windborne debris resistant or protected from windborne debris with an impact protective system (shutter). Please refer to the Texas Revisions for specific windborne debris requirements.
- Are windows, doors, garage doors, and skylights required to be windborne debris resistant in the Seaward zone?
In the Seaward zone, on all new construction, additions, renovations, and repairs, all exterior openings are required to be protected from windborne debris. This means that windows, skylights, doors, and garage doors must be either windborne debris resistant or protected from windborne debris with an impact protective system (shutter). Please refer to the Texas Revisions for specific windborne debris requirements.
