Northern Wisconsin’s Insulation And Building Science Experts

RVI-High Performance Building Experts

Rhinelander-area natives Sam and Ashly Hartmann have been working with builders and homeowners to make homes in Northern Wisconsin more comfortable since 2000. Drawing on Sam’s career in custom home construction, the couple saw an opportunity to improve the energy efficiency and sustainability of both new and existing homes in this harsh climate using a whole-home building science approach to air-sealing and insulation technology.

Working with Madison-based Focus on Energy, RVI quickly became known as building science experts, dedicated to educating homeowners and builders about modern insulation options and installing those new technologies for increased energy efficiency that improves overall home performance and comfort.

Today, RVI is known as the best insulation company in Northern Wisconsin and as

the area’s most trusted building science experts

Testimonials

I would recommend these folks to everybody

Sam and his crew did a terrific job of cleaning out 45 years of debris from our “rathole” of a crawlspace and turning it into what I now refer to as our “surgical suite”. The space is now totally dry, level, insulated and sealed. We could eat off the new plastic floor which covers our old sand base. I now even look forward to going down into what I used to refer as my personal pit from hell. It’s totally dry, clean and habitable. Sam even said that he would take care of any problems that might arise for the indefinite future. I would recommend these folks to everybody. Thanks from a totally satisfied homeowner.
