RVI

RVI We are expert insulators who combine proven insulation technology with building science knowledge.

Since inception in 2000, RVI has been a leader in innovative Air Sealing and Insulating Systems. A family, faith, customer, and community-focused business, RVI is owned and operated by Sam and Ashly Hartmann in their hometown of Rhinelander, WI. Sam started his career in the building industry over twenty years ago as a general contractor and played a pivotal role in bringing Focus on Energy to No

rthern Wisconsin. His extensive knowledge of building science and the importance of proper air sealing led him to a career in insulation. Educating contractors and homeowners on building science – the home as an operating system – has become a primary focus for Sam and Ashly, and for RVI. Through RVI, Sam and Ashly have been able to merge their passion and skillset to develop a company and team that focuses on providing home operating solutions and building science education to contractors and homeowners.
