This company was started in 2016 when I bought a rig to spray foam my own house with the plan to sell it after my house was done, but there was a need in the area for that service so it grew into a full time job. As we grew we worked at created relationships with the community & contractors. In 2018 we added fiberglass to our offerings and became a full service insulation company. By fall of 2018 we added 2 more employees, which allowed us to keep both spray foam and fiberglass! With our business continuing to grow & the shift in the marketplace towards spray foam, we have added a second rig to our operations! We are proud of our team of 5 & value our customers by making sure we meet their spray foam or fiberglass insulation needs

Our story begins in a garage with 2 employees (Kevin and Yvonne Kinzler). Kevin worked hanging drywall in between 24 hour shifts as a full time fireman. One day in 1988 a customer calls with a huge problem. With hogs en route and the Iowa winter coming fast, the customer’s insulation contractor stood him up. He called Kevin for a solution. First, Kevin agreed to do everything he possibly could to solve the customer’s problem. Next, he employed every friend, coworker, and family member possible (including 8 year old son Tanner) and Kinzler was in the insulation business. To outsiders it may look like Kinzler has expertly grown its business to move into expanding insulation markets over the last 30 years. Insiders know each growth opportunity came from solving a problem for an existing customer. Today, we solve commercial, agricultural, contractor, business and homeowner problems. We have added a few employees and locations, but our customer-focused problem solving and service remains the same.

Insulation questions, answered by experts

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

Yes, guiding choices between open-cell and closed-cell foams based on needs.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Ductwork sweats for the same reason you might find beading on your windows or why cold drinks drip in the heat—temperature difference. When you see your ductwork and you notice sweating, that's a sure sign that your system is not operating anywhere close to peak efficiency. The best way to keep ductwork from sweating is to wrap it in inadequate insulation.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.
