Container Home Insulation Planner

This planner helps you determine the insulation requirements for your shipping container home by:

  • Visualizing your selections with animated diagrams and checking if they meet the required R-values.
  • Selecting your state and climate zone to view required R-values.
  • Choosing insulation types and thicknesses for the floor, ceiling, and walls, with a special option for walls (inside or outside insulation).

Container Insulation Planner

Select your location, configure insulation for each assembly, and watch the cross-section update in real time. Generated notes can be adapted for use in your project documentation.

How It Works

Ready to get your shipping container home insulated? Our interactive planner’s got your back, making it simple to nail those building code requirements. Here’s how it rolls:

1. Tell Us Where You’re Building

  • State Dropdown: Pick your state from all 50 U.S. options.
  • Climate Zone Dropdown: Depending on your state, choose your climate zone (like Arizona’s 2B, 3B, 4B, or 5B).
  • What You Get: Boom—see the exact R-values you need for your ceiling, walls, and floor, straight from IECC 2021 standards.
    (R-values? They’re just a number showing how well insulation blocks heat—bigger is better!)

2. Discover Your Required R-Values

  • Once you lock in your climate zone, the planner spits out the R-values you’ve gotta hit. For example, Zone 3 might show Ceiling R-38, Walls R-20 or R-13+5, and Floor R-19. It’s custom-fit to your spot!

3. Plan Your Insulation Like a Boss

  • Floor and Ceiling:
    • Pick your insulation vibe: Spray Foam (R-6 per inch), Batt (R-3.5 per inch), or Polyiso (R-6 per inch).
    • Slide that thickness up or down in inches.
    • Watch the R-value update live and see if you’re good to go.
  • Walls:
    • Go with Cavity Only or mix it up with Cavity + Continuous.
    • Decide if the cavity insulation sits Inside or Outside the container.
    • Dial in types and thicknesses for both layers (if you’re doubling up).
    • The tool checks if you’re hitting targets like R-30, R-20+5, or R-13+10 and gives you a big “You’re good” or “Not yet” sign.

4. See It All Come to Life with Animations

  • Floor: Crank up the thickness and watch the insulation stack up from the base.
  • Ceiling: See it drop down as you beef up the layers.
  • Walls: Insulation pops up inside, outside, or both—moving with your choices like a live blueprint.
    These visuals make it crazy easy to picture how your setup fits together.

With this planner, you’re not just figuring out insulation—you’re crafting a energy efficient, code-ready container home. Jump in and start messing around with the perfect setup for your build!
