INSULATORS 19
MWSC | MAC | 120TH
HEAT & FROST
APRIL 28th - MAY 1st
1906 - 2026
In 1906, a group of skilled mechanical insulators in Milwaukee laid the foundation for what would become Heat & Frost Insulators Local 19. 120 years later, we’re bringing members, families, contractors, industry partners, and friends together from across the United States and Canada to celebrate that legacy.
This is a tribute to: the workers who built our union, the industry that powers modern infrastructure, the city of Milwaukee that shaped our identity. Set in the historic beer district, the week blends Milwaukee's beer history, union craftsmanship, pride, great food, and unforgettable experiences.
