1.1 Definitions

Refer to the Glossary for further definitions of key terms used in this Manual.

Primary Material
means a roofing, waterproofing or water-shedding material which is directly exposed to the weather and which is primarily responsible for protecting secondary materials, and the building interior, from water and weather generally. Membranes, metal panels or shingles form the core of this material type.
Secondary Material
means one which forms part of a waterproofing system or water-shedding system and which may affect the wind resistance characteristics of the entire assembly but is not necessarily exposed to the weather.
