The Journey to Market - Starting Down the Path to Fenestration Product Testing

Are you a European window or door manufacturer that is interested in entering the United States or Canadian markets? Or are you a U.S. manufacturer attempting to penetrate the European market?

You should also consider if your product is going to be geared toward the residential housing market or if it is intended for use within a commercial application.

If your products will best fit a residential market, you should follow the International Residential Code (IRC) in the U.S., and if your products are more geared towards a commercial application, they will require a look at the International Building Code (IBC). All fenestration products within the Canadian market would follow performance requirements as listed with the National Building Code of Canada. In the U.K., performance requirements are specified through the police force per Secured by Design.

Your market goals will dictate how you move forward and which building codes or country requirements you will need to explore.

Review the building codes required in your area

Reviewing the building codes required in the regions you will be selling your products in will guide you on your path to understanding what test standards are referenced and required in your desired market. Knowing these test standards will guide you in what your products will be tested and certified to in the future. This overview of U.S. Building Codes provides a flow of how model codes will define performance requirements that are tested through developed test standards.

While the image above depicts how building codes in the United States influence test standards, at UL Solutions we have regional expertise around the world to help you navigate the codes and test standards in the market(s) you are intending to enter. If you have specific questions about fenestration testing, please do not hesitate to reach out to us with any questions at [email protected].

It might seem strange that testing and certifying your full product falls near the middle of this list, but depending on your region and its requirements, your product may not meet the certification requirements if its individual parts have not been tested individually first. If your product’s glass and component parts have passed testing and certification requirements, you can move on to testing and certifying your fully assembled product that contains the approved glass and components. If you go out of order and submit your full product first, you may have a problem getting your full assembly certified with your third-party certification agency.

Many municipalities' laws, codes and regulations require certain building products and systems be tested and evaluated before they can be installed in a jurisdiction. A product can be tested and may not necessarily be third-party certified. Being third-party certified means the product has been evaluated, complies with the requirements of the third-party organization and is manufactured under a quality control program with third-party inspections/follow-up service. Some companies choose to certify with a third-party to minimize the safety risk that may be associated with their products.

Do you know if your products can meet the thermal requirements of your desired market? Is your customer asking you for higher rated windows than how your design currently performs?

In the United States and Canada, the North American Fenestration Standard (NAFS) is used to define performance requirements for specific design pressure (DP) or performance grades (PG). NAFS is the window, door and skylight requirement of the International Building and Residential Codes for the U.S., and for the National Building Code of Canada. These codes require you to test and properly label windows, doors and skylights in accordance with this specification, which indicates these products are rated to perform in the area they are being installed.

Your next step is to check that you have tested the product’s component parts as well as its glass and glazing systems. Window and door component parts are expected to be tested and verified by a third-party agency. These components include sealants, hardware, weather strips and foam to name a few examples.
