Introduction to Insulating Your RV for Winter Comfort
If you will be doing any winter camping or winter RV living, proper insulation of your RV or camper is one of the most important factors to consider in order to not only keep your RV cozy inside but to protect your equipment against the harsh winter elements. There are several options available when it comes to insulating your RV against winter temperatures. Cost, ease of sourcing materials, bulky materials, and permanence of insulation are all common challenges that come along with insulating an RV for the winter. EZ Snap products are one solution to keeping the chill out that resolves many of these concerns.
Comparing Common Insulation Types for Your RV
First, look at some common insulation types and their benefits. Foam board insulation is perhaps the easiest material to source. You can find foam board insulation at most home improvement stores, often with several sizes and thicknesses to choose from. While installing foam board insulation is not a permanent installation, the materials are quite bulky and bring with it the challenge of what to do with the foam board at the end of the season when spring comes again and it’s time to remove the insulation.
Reflective insulation, while less bulky than foam board, is also a non-permanent solution. Reflective insulation can also be sourced at many home improvement stores and comes in rolls of various R-values. When removed in the spring, it again brings with it the challenge of what to do with the used insulation after it’s removed as it’s not simple to store for future re-use.
Spray foam insulation is a more permanently installed insulation that is applied to the underbelly of the RV to help insulate the pipe against the elements. It can be quite costly to insulate the underbelly fully with spray foam and is also difficult to remove in the future should the need arise.
Key Considerations for Choosing Insulation Materials
RV skirting does not require a high R-value to be effective in insulating your RV. The temperature differential between the inside and outside air beneath the RV is minimal due to the use of electric heaters, and the R-value savings would be insignificant. Furthermore, to achieve significant energy savings, RV skirting would need to be much thicker than it typically is. Stopping air movement is far more critical than R-value when it comes to RV skirting; a barrier to airflow alone is sufficient for most situations. In extreme winter climates, using rigid Styrofoam insulation board in conjunction with RV skirting is the most effective way to add insulation. Lastly, thermostatically controlled space heaters with built-in fans are the best heat source to use under RV skirting, as they only use energy when needed.
Insulating Your RV: Windows, Doors, and Floors
Window Insulation: Reducing Heat Loss with EZ Snap Window Shades
EZ Snap window shades are a valuable layer to your insulation equation as they help retain heat inside of the RV by adding a layer of insulation over your windows, protecting against the elements. Installation is simple with EZ Snap’s patented no-drill installation system. You can mount the fasteners to either the side panel, if it’s smooth and flat, or to the glass itself, cut the non-fray solar shading mesh to the size of each window, and install. (“EZ Snap”)
Door Insulation: Proper Sealing and Weatherstripping
Choosing the right weatherstripping material is another important factor to take into consideration. While some materials provide more insulation against cold temperatures, others are better suited to holding up against snow and ice or sub-zero temperatures. Thinking about the conditions where you live will help you choose the best material for your weatherstripping needs. Once you have selected your weather-stripping material, you’ll need to measure around your door to determine how much weather-stripping you will need. Next, you will cut the weatherstripping to size and allow a little excess to ensure that it will have a tight fit once installed. You can always trim it down later, if necessary. Finally, install the weatherstripping around the door, trim any necessary pieces that overlap, and test the door to ensure a proper seal with your new weatherstripping.

Floor Insulation: Essential for RV Comfort and Plumbing Protection
Insulating your RV’s floors is an important step not only to help keep the chill out of your RV’s interior but also to help protect your RV’s plumbing system. Both freshwater and sewer pipes for your RV travel below the floor of your RV, so keeping those insulated also ensures that your plumbing system remains in tip-top shape throughout the cold winter months. To insulate your floors you could choose fiberglass, foam board, or spray foam insulation options. Each comes with varying costs, ease of installation, and the degree to which it provides insulation protection against the elements. While fiberglass insulation is the cheapest option, it’s the least suited for snow and wet weather which will require something like corrugated plastic to cover the fiberglass when you install it. Foamboard provides higher levels of installation but is the bulkiest and most costly of the three options. Spray foam insulation is more moderately priced but provides lesser protection against cold weather than foam board and is a more permanent solution. Choosing the best floor insulation for your needs is important and properly installing it will ensure the maximum protection for your RV. (“RV Insulation 101”)
Walls and Ceiling Insulation: Enhancing Comfort and Heat Retention
Enhancing Wall Insulation and Protecting RV Plumbing with Skirting
RVs come from the factory with varying levels of insulation. One option to increase the R-value of your RV’s wall insulation is to use spray foam insulation to supplement your RV’s existing insulation. Skirting your RV using a product like EZ Snap RV Skirting Kits provides a simple, easy-to-install solution that adds insulation to parts of your RV’s walls while also offering extra insulation to the underbelly and safeguarding vital plumbing lines. EZ Snap’s diamond-weave material is designed for extreme weather down to -40 degrees Fahrenheit and is lightweight, easy to cut to size, and resistant to mold and mildew—crucial factors considering it will be wrapped around your RV for several months each year.
Roof Insulation: Minimizing Heat Loss and Ensuring Warmth
Ceiling insulation might not be the first area of insulation that you consider when thinking about protecting your RV from cold temperatures, but since warm air rises, it’s where heat can easily be lost if not well-insulated. While keeping your roof cleared of snow and ice as much as possible is important, so is insulating your roof. One aspect to consider is any skylights or vents. These can be fitted with foam insulation pillows to reduce heat loss through the thin plastic windows which do not come insulated from the factory.
Optimizing Heating and Ventilation for Winter RV Comfort
Efficient Heating Systems
Keeping your RV’s propane or electric furnace in top condition is the first step to ensuring an efficient heating system. Making sure that all of your ductwork is clean, and vents clear to allow for maximum airflow to all areas of your RV will also help to keep your RV cozy inside. Some RVs come equipped with an electric fireplace heater or these can be added aftermarket to up the heat output in your RV. If your RV is larger or if you find that you need additional help heating your RV, ceramic space heaters used for short periods of time during the day can help raise the inside air temperature of your RV, keeping you warm and cozy inside. Never leave these unattended or running overnight.
Ventilation and Humidity Control
Proper ventilation is always important, but especially in the winter when you are sealing around your RV to insulate and keep the heat in and the cold out. Making sure that your RV’s propane is properly venting to the outside and not back into the RV is a critical safety consideration. Humidity is also a common battle during the winter months as condensation tends to settle on the walls, windows, and ceiling of the RV if left unchecked. Running a dehumidifier inside the RV throughout the winter will help to pull the humidity out of the air, preventing mold and mildew. These can quickly destroy your investment in your RV, so don’t skip on managing humidity, particularly if you are in a humid climate.
Evaluating your RV’s insulation needs and ensuring its proper insulation using the right products and equipment will ensure a cozy winter RV experience for you. Protecting your equipment by insulating your RV efficiently and properly will also extend the life of your RV, ensuring your enjoyment of your RV for years to come.
