General fenestration product design and manufacturing questions
- How do I know what standards I need to test my fenestration products to?
Your first resource to understand what standards you should be testing your products to, is to confer with the project’s architect or building owner. These stakeholders should be able to refer you to the proper test standards commonly required by the location your products will be sold.
In the event that an architect or building owner is not available to you, you may also consult the trusted resources of the Construction Specification Institute (CSI). CSI is dedicated to advancing building information management, communication, and education to improve facility performance.
- How do I meet Energy Star Requirements?
Meeting energy efficient product requirements are increasingly becoming a key factor in a customer’s decision-making process and could be the tie breaking factor in a competitive product situation. Energy Star products utilize quality materials that will be durable enough to meet specific performance criteria aimed to meet the climate the product intends to serve. Generally, qualified Energy Star windows, doors, and skylights meet the following criteria:
- They are manufactured by an ENERGY STAR partner
- Are independently tested, certified, and verified by the National Fenestration Rating Council (NFRC)
- Have NFRC ratings that meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA).
