Project Tips

DIY Tips

Take your time removing interior panels. Label everything and take photos before disassembly.

Spray Foam Note

Spray foam requires professional installation but provides excellent air sealing and R-value.

Best Practice

Always add a vapor barrier to prevent moisture buildup and potential mold issues.

Recommended Installation Order

1

Ceiling First

Most heat loss occurs through the ceiling. Start here for maximum impact.

2

Walls Second

Walls provide the next biggest improvement in comfort and efficiency.

3

Windows & Doors

Air sealing around openings is quick and cost-effective.

4

Floor Last

Most difficult to access. Consider if other upgrades aren't sufficient.

Understanding RV Insulation

Why Upgrade Insulation?

RV insulation upgrades can dramatically improve comfort and reduce energy costs. Factory insulation is often minimal, designed for summer camping rather than year-round use. Adding quality insulation creates a more stable interior temperature, reduces condensation, and cuts heating/cooling costs by 20-40%.

Material Choices

Rigid foam board offers excellent R-value and is DIY-friendly. Spray foam provides superior air sealing but requires professional installation. Fiberglass is budget-friendly but can settle over time. Consider your budget, skills, and climate when choosing materials.

DIY vs Professional

DIY installation can save 40-60% on labor costs but requires careful planning and execution. Professional installers bring expertise and warranty coverage. Consider DIY for walls and ceiling if you're handy, but leave spray foam and floor work to professionals.

Common Mistakes to Avoid

  • • Skipping vapor barriers leads to moisture problems
  • • Compressing insulation reduces R-value
  • • Ignoring thermal bridges creates cold spots
