St. Croix Insulation Inc. started as a home-based, one-man business in 1984.

We serviced the St. Croix Valley area by installing fiber glass batts and blown-in insulation in residential and commercial buildings. Over the years, this has remained the bread and butter of our business. In 1996, we expanded our focus and began installing Poly-Wall, a foundation coating used for damp-proofing and water-proofing. In 2000, due to business growth, a new building was constructed and we moved to what is our current location, 652 Commerce Drive, Hudson, WI. In 2002, SPF (sprayed polyurethane foam) was added to our service line-up to meet the continually changing needs and wants of our customers.

Currently, St. Croix Insulation Inc. employs 19 people. This includes 15 installers, 2 sales and 2 office personnel. There are 2 corporate officers: Mike Bierbrauer, president and Jodie Bierbrauer, secretary/tresurer.
