The substitution criteria presented in Annex A1 are intended to equitably serve the needs of both fenestration product users and suppliers. The importance of fenestration in maintaining the integrity of a buildings envelope during a windstorm capable of generating wind-borne debris is recognized. These criteria were developed through careful consideration of the technical and economic factors associated with providing a variety of products to the marketplace that are reliable, affordable, and readily available. This task group intends to re-evaluate the current substitution criteria to allow for product modification, more options and more qualified assemblies to be brought to the marketplace, in a faster and more economical manner.
