The Ultimate Guide to Foam Board for RV Skirting
RV skirting is a smart way to protect your home on wheels. It acts as a barrier against cold air, wind, and snow. Foam board is the most popular material for this task. It is affordable, easy to cut, and provides excellent insulation. This guide will help you choose the right foam board for your RV.
Key Features to Look For
- R-Value: This number measures insulation power. A higher R-value keeps your RV warmer in the winter.
- Thickness: Most boards come in 1-inch or 2-inch sizes. Thicker boards offer better thermal protection.
- Moisture Resistance: You want a board that does not absorb water. Wet foam can grow mold and lose its strength.
- Durability: Your skirting will face wind and debris. Look for boards with a tough outer skin.
Understanding the Materials
There are two main types of foam board used for RV skirting:
1. Extruded Polystyrene (XPS)
XPS is usually pink, blue, or green. It has a smooth surface and closed cells. This means it resists water very well. It is strong and holds up well to heavy wind.
2. Expanded Polystyrene (EPS)
EPS is the white, beaded foam. It is cheaper than XPS. However, it is not as strong. It can crumble over time if it is not handled carefully.
Factors That Affect Quality
You want your skirting to last all season. Quality depends on a few simple things:
- Density: Higher density foam resists dents and cracks.
- Facing Material: Boards with a plastic or foil skin last longer. These skins protect the foam from sun damage and scratches.
- Installation Method: Using high-quality tape or specialized clips keeps the panels in place. Poor installation leads to loose boards that blow away.
User Experience and Use Cases
Most RV owners install foam skirting to save money on heating bills. It creates a warm “dead air” space under the RV. This prevents your water tanks and pipes from freezing. Many users find it easy to cut the boards with a simple utility knife. You can fit them to the shape of your RV frame. For a clean look, many owners paint the boards or cover them with decorative skirting fabric.
10 Frequently Asked Questions
Q: Is foam board skirting worth the cost?
A: Yes. It pays for itself by reducing your propane or electricity usage during cold months.
Q: How thick should the foam board be?
A: Most experts recommend at least 1-inch thick boards. Use 2-inch boards if you live in areas with extreme sub-zero temperatures.
Q: Can I reuse the boards next year?
A: Yes. If you store them carefully, you can use the same panels for multiple seasons.
Q: What is the best way to attach them?
A: Many people use heavy-duty duct tape, Velcro, or specialized RV skirting clips that attach to the frame.
Q: Will foam board stop mice from getting in?
A: Foam board alone is not rodent-proof. You should add wire mesh behind the foam to keep pests out.
Q: Do I need to seal the edges?
A: Yes. Use weather-resistant tape on all seams to stop cold air from leaking through.
Q: Can I paint the foam board?
A: Yes, but use water-based latex paint. Oil-based paints can melt the foam surface.
Q: Is the foam board heavy?
A: No. It is very lightweight and easy for one person to install.
Q: Should I leave a gap for ventilation?
A: Always check your RV manual. Some RVs require small vents to prevent moisture buildup under the floor.
Q: How do I store the boards in summer?
A: Keep them in a dry, shaded area. Direct sunlight can break down the foam over time.
