Fiberglass vs Aluminum RVs

There’s a pretty even split between aluminum and fiberglass RVs in the market today. Fiberglass models are typically smooth, while aluminum ones have the characteristic ridges along the sides. Fiberglass models are still somewhat recent additions to the RV world, but they have lots of great benefits.

Fiberglass Pros and Cons

To start off, fiberglass Rvs have better insulation. The exterior material and insulation composition make it easier for these vehicles to retain heat. If you want to reduce volume as well, fiberglass is a great material for noise cancellation. It absorbs heat and sound quite well, which has made it a popular choice. This material is also easier to clean compared to aluminum. Dirt doesn’t stick to it as easily. In addition, fiberglass is more resistant to dents and breakage. Even if holes to appear, it’s fairly easy to fill them in as long as they are small.

Fiberglass is generally lighter than aluminum as well, so having a camper with this type of siding means that it’s lighter and requires less gas. Overall, this is a great material, especially if retaining heat is your main priority. The main drawback is that fiberglass RVs tend to be more expensive than their aluminum counterparts. They are also prone to UV damage, so you’ll have to be extra careful to apply the proper coatings and use covers to protect the exterior.

Aluminum Pros and Cons

Rvs with aluminum siding are also fairly popular. Even though fiberglass may be your better choice for winter camping, there are still lots of benefits to getting an aluminum RV. For starters, they tend to be cheaper than fiberglass! Aluminum is somewhat prone to denting, but it’s fairly easy to repair. You can also just replace damaged sections without performing an extensive repair. This is harder to do for fiberglass RVs, so the maintenance is a benefit.

On the downside, aluminum RVs aren’t as good at regulating temperature. They tend to get quite hot when left under the sun, and will freexe faster than a fiberglass model. They can also be harder to clean and are often less aerodynamic because of their ridged surface. Both aluminum and fiberglass are suitable materials for an RV, but fiberglass is definitely the better pick if you plan on using the vehicle for cold weather camping.

Other Ways to Improve Your RV Insulation

Buying a good cold weather fiberglass RV is a great place to start, but there are other things you can do to keep your vehicle warmer in the winter.


RV skirtng helps to protect and insulate the base of your RV. The material is supposed to keep the heat inside and protect any tanks, wires, or pipes from freezing. You can use custom skirting that’s tailored to your RV, or make you own with tarps, styrofoam, cardboard, or any other material that provides an extra layer of protection.

Window and Vent Covers

Windows, doors, and vents are major sites for heat leaks. If your RV seems to lose heat quickly, make sure the seals around your windows and doors are unbroken. Double paned windows will make it easier to retain heat. Using fitted covers for your vents and windows will also keep the interior warmer. Even covering entryways with a curtain or blanket can help prevent heat loss.


Carpeting and rugs can help the floor of your RV stay warm. If you feel like your feet are always cold and the floor is letting heat out, use a few rugs and consider laying some carpet in your RV. This is a small fix, but it can make a big difference in your comfort level.
