MASTER FLASH® FEATURES
 WEATHER PROTECTION
Made of EPDM or Silicone, these flashings are compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light.
EASY ON-SITE CUSTOMIZATION
Fast, one piece construction allows for easy on-site installation in usually 5 minutes.
BASE FLEXIBILITY
The soft aluminum base is designed to form a seal on most panel configurations and roof pitches regardless of pipe location.
DESIGN EXCELLENCE
Aztec's flexible design meets virtually all roofing needs. Sleeve flexibility accommodates vibration and pipe movement caused by expansion/contraction. the soft aluminum base easily conforms to roof panels. Master Flash® was used to create a new engineering standard for profiled roofing by the International Association of Plumbing and mechanical Officials(for the uniform Plumbing Code) and remains the only product listed. These products are also listed for use with Type B vents. The addition of fire retarding agents milled directly into the rubber compound created a self extinguishing feature which enables it to be used with Type B vents. Listed with IAPMO certification No. 3121.
