Whether you’re traveling full-time or taking weekend adventures, your RV should feel like home — warm in winter, cool in summer, and protected from condensation. The right insulation makes all the difference in comfort, energy efficiency, and durability.
Common RV Insulation Options
Fiberglass
Inexpensive but absorbs moisture and loses effectiveness over time. Can sag, compress, and irritate skin during installation.
Rigid Board
Provides structure but adds weight and is difficult to fit in curved RV walls and tight cavities. Gaps between panels can lead to air leaks and condensation.
Spray Foam
Seals well but is expensive, permanent, and can off-gas during installation. Hard to modify later if you need to access wiring or plumbing.

Common RV Insulation Mistakes to Avoid
Using moisture-absorbing materials: Fiberglass and cellulose can trap condensation, leading to mold or odor.
Over-insulating: Too much material can block ventilation and cause dampness inside wall cavities.
Ignoring radiant heat: Many RV owners overlook the impact of radiant energy — reflective insulation like Prodex helps control it efficiently.
Skipping vapor barriers: Always use a vapor barrier to prevent interior condensation, especially in climates with large temperature swings.
FAQ — RV Insulation and Prodex Total
Q: What is the best insulation for RVs?
A: The best insulation for most RVs is a reflective, multi-layer material like Prodex Total. It provides radiant heat control, a built-in vapor barrier, and a thermal break — all in a thin, lightweight layer that’s easy to install and ideal for mobile living spaces.
Q: How does Prodex Total compare to fiberglass or spray foam?
A: Unlike fiberglass, Prodex does not absorb moisture or lose performance when damp. It’s easier to install than spray foam, produces no mess or fumes, and can be removed or adjusted later if needed. It’s a practical and durable alternative for DIY RV owners.
Q: Will Prodex Insulation prevent condensation in my RV?
A: Yes. Prodex Total includes a built-in vapor barrier and reflective foil surface that help block condensation — a common problem in RVs and campers where warm indoor air meets cold surfaces.
Q: Is Prodex Insulation safe and non-toxic?
A: Yes. Prodex Total is non-fibrous, non-itchy, and free from chemical off-gassing during installation. It’s safe to handle and suitable for small, enclosed spaces like RVs, vans, and campers.
Q: How thick is Prodex Total, and will it reduce my interior space?
A: Prodex Total thickness ranges from 0.2 inch to 0.4 inch, yet it performs like much thicker materials by reflecting radiant heat and blocking moisture. It’s ideal for RVs where space is limited.
Q: Can I install Prodex Insulation myself?
A: Absolutely. It installs easily using staples, adhesive, or tape. Many RV owners complete full installations in a single weekend without special tools or professional help.
