This or That: Aluminum vs Fibreglass RV Siding

14 June 2018

If you walk onto any RV dealership or campground, you'll be greeted by two main types of RV exteriors - Aluminum and Fibreglass. Each have pros and cons and have a place in the RV market. Today we're going to explain the main differences between Aluminum and Fibreglass RVs to help you understand which option is the best choice for you. 


Aluminum RVs typically have ridges. Commonly referred to as 'Stick-n-Tin', Aluminum walls have been around since the 1940's and are the more traditional exterior. While that might make you think of stick-n-tin RVs as dated, there's a reason they're still being manufactured and bought almost 80 years later. 


  • Price. Aluminum RVs can be thousands of dollars less than Fibreglass options, a perfect choice for the first time RV buyer trying on the lifestyle.
  • Repairs. If you get into an accident with an Aluminum RV that results in dents or damage to your wall, in most cases you can get away with replacing a single panel of siding. With Fibreglass RVs, you may have to replace the entire side to repair damages to one section.
  • Insulation. Aluminum RV walls are composed of the outer layer of aluminum, a wood frame, fibreglass insulation and dead air space beneath. This space gives an added layer of protection from the elements that other insulation types do not offer. 



Fibreglass RVs have smooth, glossy finishes. They are usually composed of a resin plastic, reinforced with fibreglass and treated with a gel-coat. Many people just prefer the sleek look of the fibreglass RV, but there are many other benefits you may not know about.


  • Overall cleanliness. Because of their matte finish, stick-n-tin RVs tend to hold onto dirt where fibreglass RVs are easily cleaned and maintain that 'new' look due to their shine. 
  • Resale value. Fibreglass RVs hold their resale value better than aluminum models, so if you're planning to invest in an RV you can trade-in down the road you may want to go the fibreglass route. 
  • Gas mileage. Due to their lighter weight and smooth, aerodynamic finish, fibreglass RVs are easier to tow and easier on the gas bill as well. 

At the end of the day, both Aluminum and Fibreglass models have their place in the market and in the campground. It really comes down to buyer's choice - what type of camper will you be? Will you be towing frequently? Will your travels be rough on your trailer and require many repairs? What is your budget? Are you looking for a trailer that will offer you a good trade-in value down the road?
