Dr. Paul Bove, an engineer with the Texas Department of Insurance (TDI), explained to members of the Fenestration and Glazing Industry Alliance (FGIA) what companies need to do to submit an evaluation report request in accordance with TDI’s Windstorm Program requirements for fenestration products. In the webinar titled, “FGIA Webinar: Texas Department of Insurance (TDI) Update,” Bove explained that the program is voluntary and operates in 14 Texas counties along the Gulf Coast in a designated catastrophe area.

The program exists to provide insurance coverage for those who want to operate a commercial space or buy a home in this area of Texas. The Texas Windstorm Insurance Association was established to act as a last resort, according to Bove, meaning if one is unable to obtain insurance coverage through a voluntary carrier, one can go to TWIA.

In the seaward portion of this region there are windborne debris requirements for all exterior openings. In the inland one zone, windborne debris requirements exist for glazed openings only and in the inland two zone there are no windborne debris requirements.

The TDI adopts building specifications, certifies to the TWIA that structures are insurable against windstorm and hail losses, provides inspection services, processes windstorm forms, and evaluates building products for compliance with adopted building specifications.

The TDI develops evaluation reports for windows, exterior doors, skylights/tubular daylighting devices (TDD), curtainwalls and storefronts, and translucent roof and wall assemblies. Non-impact windows, doors and skylights/TDD are tested to AAMA/WDMA/CSA 101/I.S.2/A440. Impact windows, doors and skylights are tested to A440, ASTM E 1886 and ASTEM E 1996, or, as an option, AAMA 506. Non-impact side hinged doors have the option to be tested to ASTM E 330 or TAS 202. Impact side hinged doors can be tested to ASTM E 330 or TAS 202, ASTM E 1886 and ASTM E 1996, or, as an option, TAS 201 and TAS 203. Non-impact curtainwall and storefront products are tested to ASTM E 330 or TAS 202. Impact curtainwall and storefront products can be tested to ASTM E 330 or TAS 202 as well as ASTM E 1886, ASTM E 1996, TAS 201 and TAS 203.

Windows, doors and skylights must bear the inspection agency label which identifies the manufacturer/product name, the performance rating, compliance with required standards and the missile level must be indicated for impact products. Side hinged doors have the same requirements if they go through an inspection agency, but the label must also list the design pressure rating and maximum size tested rather than the performance rating. If the side hinged doors bear a manufacturer label instead, the requirements still apply, but the maximum size tested does not need to be included.

Curtainwall and storefront products must bear a manufacturer-produced label that references the design drawing, includes compliance with required standards and indicates the missile level for impact products.

Submittal Requirements

To submit requirements for fenestration products in order for the TDI to develop an evaluation report, companies must submit test reports for NAFS and impact standards, product certifications, performance labels, design drawings and analysis.

“Design drawings are beneficial for consumers,” said Bove. “The drawings include all the important aspects of a product so people can understand what a system looks like and how it’s installed.”

Design drawings typically include dimension configurations, design pressure ratings, glazing construction, installation requirements other than “as tested” and hardware requirements. These drawings are a requirement for submittals of curtainwall and storefront and recommended for windows, doors and skylights/TDD.

If the drawing illustrates as tested configurations and installation methods then it does not need to be signed, sealed and dated by a licensed Texas engineer. It does if the drawing illustrates alternative installation methods and configurations.

Bove said an electronic submittal process is in development currently and he hopes to have it in place by the end of the first quarter of 2020. In the meantime, companies must mail their submittals; separate submittals are required for each product line.

Code Updates

Bove also informed members that the TDI is proposing to adopt the 2018 International Building Code and the 2018 International Residential Code. The TDI could adopt both with a projected implementation date of March 1, 2020.
