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

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.
