My Rigid Foam Tiny House Skirt
I was pleasantly surprised at how cheap and easy it was for me to make a rigid foam skirt for my Tiny House. The cost was $72, and total labor time was 6 hours. Below I’ve listed my materials and step by step process.
My Tiny House is on a 20 foot trailer with about 16-22 inches of space between the trailer and the ground. A longer trailer, or one higher off the ground, will require more material.
- 5: Sheets of 1/2″ x 4′ x 8′ Rigid Foam
- 2: Cans of black spray paint
- 1: 60 yard roll of black duct tape
Rigid foam is readily available at hardware stores and online. I was able to save money by purchasing some of my foam sheets at Habitat for Humanity. Sheets at Habitat were $1.50 compared to $12.95 at Home Depot. That’s big savings!
Make sure you purchase the rigid insulation. Floppy insulation cannot withstand a windstorm.
How to create this skirt: Step by Step
Step 1: Spray paint your foam boards. This is a personal preference, but I didn’t like the look of silver foam boards. I painted my boards black to match my trailer. Unfortunately, I didn’t do this before attaching them to my trailer. Do as I say, not as I do!
Step 2: Measure the space between your trailer and the ground. The measurements will vary, so continue to check before every cut. Cutting around the wheels is tricky work, so I decided to skip skirting my wheels because my climate isn’t that cold.
Step 3: Cut the board to size. It was easy to cut my 1/2″ boards using a utility knife and a straight edge. I made sure to cut around vents that need to be exposed.
Step 4: Attach the board to your trailer. Using black duct tape, I attached my boards to my trailer and to each other. I buried the bottom of the boards into the ground, or placed rocks in front of them to secure them in place. Sometimes I put a few nails through the foam into the wood trim around my trailer. Use your best judgement to attach the boards as sturdily as you can. At this point, your Tiny House is skirted! CLICK HERE for advice on winterizing a Tiny House for extremely cold weather
Optional: Add cedar lattice and trim
In order to improve the look, I added cedar lattice and trim in front of my foam skirt. Aside from aesthetics, the lattice does a great job of holding my foam boards in place. Similar to creating the foam skirt, this process entailed measuring and cutting the lattice to size. I used a hand saw and a finish nail gun to attach the lattice and trim around my trailer. As with the foam, I cut around vents and my wheel wells. This additional step cost another $64.
