Insulators Local No. 97 History

Chartered in 1941, The Heat and Frost Insulators & Allied Workers, Local Union 97, started on Kodiak Island with 16 members. It's is because of the dedication of these members and each member since, that Local 97 will be celebrating its 75th anniversary next year. 

Throughout the past 75 years, Local 97 has played key roles in some very significant and nationally known projects. During this time, Local 97 has worked on many commercial and industrial projects insulating everything from heating, chilled water and domestic water systems to HVAC systems, industrial process piping and equipment. In the late 1950’s and early 60’s, the construction of the North Slope began and later, the construction of the Trans-Alaska Pipeline. Local 97 dispatched hundreds of insulation professionals to various companies during these multi-year construction projects. We had as many as 26 signatory contractors on board during what's recognized by our predecessors as “The Pipeline Days.”      

From the North Slope to Fairbanks, Bethel to Savoongah, Anchorage Bowl to the Kenai Peninsula, Juneau, Sitka and the tip of the Aleutian Chain, Local 97 continues to focus on training and providing quality, professional mechanical insulators to its' contractors throughout our vast state. 

Today, local 97 has 65 active members statewide and continually strives to build our membership as we perform mechanical insulation work throughout Alaska.
