Are Casita trailers insulated?

In today’s blog post, we will discuss: Are Casita trailers insulated? We will review the winter and summer features of a Casita trailer. We will also give you advice on how to winterize your Casita since mere trailer insulation may not be enough for some cold, cold areas!

Are Casita trailers insulated?

Yes, Casita travel trailers have an insulated interior, which means you will be able to keep cool during summer and warm in winter. Good insulation also means less noise and less interior condensation, humidity and mold issues!

Thermal insulation for the Casita trailer is achieved by applying a layer of insulating material. Any gaps are then filled with the polyurethane foam, once sprayed it will expand into the hole filling it. 

Do Casita trailers have better insulation than other trailers?

It would be difficult to compare Casita travel trailers with all other trailers, but we can say for sure that fiberglass trailers (such as Casitas) are definitely better insulated and have numerous advantages compared to aluminum trailers.

The advantages of a fiberglass trailer are numerous. Much lighter than the aluminum models, it will be more easily transportable by an SUV or even a family vehicle with a good towing capacity. Their more aerodynamic shape and more compact size make them more maneuverable models and offer reduced fuel consumption.

On an aesthetic level, they can have certain advantages over models made of aluminum sheets, such as the fact that their paint will not peel, which is not the case with aluminum coating for trailers.

If you regularly travel with your caravan to areas with adverse weather conditions, the fiberglass coating withstands hail better than aluminum, as it resists dents. Laminates over fiberglass are prone to discoloration and flaking. 

Fiberglass provides better insulation than aluminum, so the interior of the caravan will better keep warm in cold weather and stay cool in hot periods. Since fiberglass surfaces are smoother than aluminum, doors and windows generally seal more securely. 

Although fiberglass siding is more expensive than aluminum, many RV owners find its durability, beauty, and ease of cleaning worth the higher price.

Are Casita trailers 4 seasons?

Since they claim to have good insulation, Casita trailers can be considered 4 season trailers. Many travelers and RVs enthusiasts have taken their Casitas up in the mountains on cold nights, but many have complained that the foaming insulation that Casita uses is just not enough and that you will need to equip yourself well with additional heaters and warm clothes. 

4 season trailers are designed to guarantee not only your comfort with reinforced thermal insulation but also your safety on more difficult roads (snow, ice, thunderstorms, snowstorms, etc.). While Casita is a lightweight and durable travel trailer, we would recommend you to be cautious especially if you like to travel in winter!

If you, nonetheless, are serious about traveling during all four seasons in your Casita travel trailer, you will need to make sure you can keep an optimal temperature inside. This is the key to a successful trip no matter the weather outside! Here are our last tips:

  • To feel comfortable during the winter there is more than just installing a heater for your trailer. 
  • While it sounds counterintuitive, ventilation is the key to a comfortable travel trailer. 
  • Water vapor in the form of condensation can feel like it’s heating up your space, but don’t be fooled – it condenses on walls and windows and can cause major problems for the travel trailer’s integrity and your health. 
  • Keep your living area well ventilated to ensure that stale, humid air is replaced by cool, dry air. 
  • Other tips for avoiding condensation include drying laundry outdoors or in a laundromat and cooking with a slow cooker or fan oven, which is another great source of heat.
  • In summer, keep the doors, the windows and the skylights closed during the hottest hours, unless there is a light breeze or light wind that, although it will not help to cool the environment, it may make the heat more bearable.
  • Try to avoid prolonged cooking inside the travel trailer in the hottest hours of summer.
  • If you have a tarp that covers a large part of the travel trailer, feel free to use it as an awning. 
  • When you notice that it has already cooled something late at night, make sure you have constant ventilation inside the travel trailer for as long as possible, ideally throughout the night, paying attention to leaving all the mosquito nets in place.
