Our trade consists of insulating heating and air conditioning systems, domestic water and plumbing pipes in commercial buildings, power plants, and sometimes residential developments.  The materials we use consist of fiberglass, calcium silicate, foamed rubber products, insulating foams and loose fill products. We are also in the asbestos abatement industry.  We are trained and certified in asbestos removal and fitted with proper safety equipment. 

We also have a pre-apprenticeship program which we call our "Improver" program.  This person is in the Union but not in the Apprenticeship Program and is able to go to work on the same jobs and get a good feel for our trade while getting valuable on the job experience which could help him/her in becoming  accepted in the Apprenticeship program. 

Anyone interested in our Apprenticeship or Improver programs, please call for further information, Monday thru Friday at (301) 725-2400.
