Our client was very impressed with your knowledge and understanding of building science and your focus on air-sealing all of your work. He was also very impressed with your work ethic and your efficiency at executing the work at hand. I’d also like to thank you for accommodating us by shifting your schedule around on short notice, in order for us to work through the road weight restrictions that were posted sooner than expected this year.

The RVI process reduces heat loss..

“The biggest challenge to decide on RVI was the additional cost involved with the system and the fact that this insulation process does not exists, in a big way, in Chicagoland….which is where I come from. So, I knew nothing about it. After deciding on using RVI, I learned that Sam and his crew does exactly what they say and exactly when they say they will do it. I have two houses on my property. The first one was built 3 years ago and has conventional insulation. There is no doubt, as it can easily be seen, that snow melts on the roof of the 3-year-old house but does not melt on the RVI roof. Which tells me that the heat loss on the conventional insulation is much greater than the RVI system. Also, I’ve noticed that there were times in the RVI house that the furnace would not run for long periods of time, as the house would hold heat very well.”

RVI delivers quality work…

During the process of building a new home with a local builder, I happened to see a job that RVI was working on and immediately recognized the quality of the work. After chatting with Sam, I knew that, while my builder used a different insulation contractor, I wanted to work with Sam if possible. Luckily my builder was flexible, and the quote Sam provided was extremely competitive, especially given the increased level of air sealing and insulation R-Value provided. I was extremely impressed with all aspects of RVI’s work and even more so with the quality of the end product. We have been heating our house now with propane through the past two winters and our average home heating index (BTU/HDD/SF) is approximately 3.2, which I am extremely happy with, especially given the number and size of north facing windows in our home. I can’t recommend RVI enough and strongly encourage folks to consider them, even if they are not associated with their home builder/contractor.

RVI delivers customer satisfaction…

RVI was recommended to me by several people that had positive experiences. One person is a contractor who said, “If I could rip out all the drywall in my house and re-insulate, I would use RVI and the BIBS system without hesitation!” Another person said, “It gets so warm in my house in the winter, when I burn my fireplace, that I have to open the windows to cool it down.” Personally, I was very impressed at the time that Sam took to explain how BIBS works and why it is better than traditional insulation. I was also very impressed with the personal level of attention at the job site. Before the house was ready to be insulated, Sam stopped out to make sure the framing was ready and nothing would delay them once they started. Once the project was complete, I got to put it to action during these cold northern Wisconsin winters. I have a wood burning fireplace and when I light a fire in the morning, the house is still warm enough when I get home from work that the furnace did not have to start up. It is much the same overnight with the heat. When I wake up, the house has only dropped a few degrees from when I went to bed, even though the fire barely has any hot coals left. RVI’s attention to detail has allowed me to live in a warm home all winter. Also, in the summer, the humidity stays down and the temperatures stay low. I don’t even need to have an air conditioner. Thank you for your attention to detail and personal attention to help create a house that will stay well insulated for my lifetime and not deteriorate like traditional insulation.
