5 Top Insulation Choices for Under Your Mobile Home
Insulation for under your mobile home is crucial for warmth and energy savings. Choose from fiberglass batts, foam board, spray foam, reflective insulation, or insulated skirting based on budget and needs.
If you’re cozied up in a mobile home, don’t let a drafty floor chill your toes! Insulation is your unsung hero, and we’re diving into the top five materials that’ll keep your feet toasty and your energy bills down.
Insulating your mobile home is like a warm hug, keeping the heat inside where you need it. Underfloor insulation is crucial, preventing heat loss and lowering energy costs. The underbelly faces elements, so the insulation must withstand moisture and pests while maintaining interior temperature. Balancing material effectiveness, durability, and cost is key to energy efficiency and comfort.

1. Fiberglass Batt Insulation
Fiberglass batts are the old faithful of insulation, with a track record as long as the road trips you dream about. Easy to install and relatively inexpensive, they fit snugly between floor joists, keeping the chill at bay. They come in various thicknesses and R-values (a measure of thermal resistance), so you can choose the level of insulation that suits your climate and budget.

Pros and Cons of Fiberglass Batts
Fiberglass batts are a wallet-friendly option that can be a DIY dream—if you don’t mind a bit of itchiness during installation. They’re effective insulators, but they can absorb moisture, which reduces their insulating properties and can lead to mold. Also, they’re not the best at deterring pests, so you might need to add a critter barrier (always a fun weekend project, right?).
2. Foam Board Insulation
Foam board insulation is like the memory foam of the insulation world—it holds its shape and provides excellent R-values. It can be cut to fit any space, making it versatile for those quirky corners under your mobile home. Plus, its rigidity means it won’t sag over time, ensuring consistent insulation for the long haul.
Benefits of Using Foam Board
Foam board is like a fortress against heat loss, boasting high insulating properties and moisture resistance. It’s a champ in preventing energy from seeping out, and its solid form deters rodents looking for a cozy home. Installation is straightforward, but make sure it’s snug; any gaps can be an open invitation for cold air.
3. Spray Foam Insulation
Spray foam insulation is the high-tech suit of armor for your mobile home’s underbelly. It expands to fill every nook and cranny, creating an airtight seal that’s hard to beat. While it’s pricier upfront, its superior insulating ability can lead to long-term savings on your energy bills.
Spray Foam: Is It Worth the Cost?
Spray foam might make your wallet wince initially, but it’s a heavyweight champion in the R-value arena. It’s impervious to moisture and creates a barrier against pests. However, it requires professional installation—no DIY here—which adds to the cost. If you’re planning to stay put for a while, the investment could pay off.
4. Reflective Insulation
Reflective insulation is like putting a shiny sun hat under your home; it reflects radiant heat, keeping your space cooler in the summer and warmer in the winter. It’s typically made of foil-faced paper, plastic film, or cardboard, and it’s especially effective in hot climates where radiant heat is a major concern.
Reflective Insulation: Best Practices
To get the most out of reflective insulation, ensure it’s installed with an air space to maximize its heat-reflecting superpowers. It’s more lightweight than other options and can be a supplemental shield when paired with another form of insulation. Just remember, it’s less effective in colder climates (so don’t ditch your parka just yet).
5. Insulated Skirting
Insulated skirting is like the security blanket for your mobile home’s underside. It not only insulates but also beautifies, hiding the structural elements and adding curb appeal. It’s a two-in-one solution that can be particularly effective in moderate climates.
Insulated Skirting: Installation Tips
Installing insulated skirting is a weekend warrior’s project that can pay off big in improved aesthetics and energy savings. Make sure to measure accurately and seal all joints to prevent air leaks. Ventilation is also key to avoid moisture buildup, so don’t skimp on those vents!
Comparing Insulation Performance
When comparing insulation options, consider R-values, moisture resistance, and your local climate. Fiberglass batts and foam boards are great for tighter budgets, while spray foam offers top-notch insulation at a higher cost. Reflective insulation and insulated skirting can be excellent choices depending on your specific needs.

- Insulation plays a crucial role in maintaining comfortable indoor temperatures by reducing heat transfer.
- The temperature inside an uninsulated attic can exceed 130 degrees Fahrenheit, but proper insulation significantly lowers this temperature.
- Approximately 40 to 50 percent of heating and cooling bills are attributed to inadequate insulation.
- Foam insulation boasts the highest R-value at 6 per inch, making it the most effective insulator among the three types discussed.
- Cellulose insulation follows with an R-value of 3.4 per inch, while fiberglass has an R-value of 3.2 per inch.
- Foam insulation is the most expensive option, costing between $2.90 to $3.20 per square foot, followed by cellulose at 85 to 95 cents, and fiberglass at 50 to 80 cents.
- Air infiltration properties vary among insulation types, with fiberglass exhibiting the highest air leakage when subjected to fan movement, indicating a need for additional sealing.
- Cellulose insulation shows moderate air movement, suggesting the necessity of pairing it with caulking or foam sealant for optimal effectiveness.
- Foam insulation demonstrates minimal to no air movement, providing both the desired R-value and effective sealing properties.
- Regardless of the type chosen, achieving an R-value between 33 to 38 is recommended for proper insulation and energy efficiency, ultimately reducing heating and cooling costs and enhancing indoor comfort.
Maintenance Tips for Underfloor Insulation
Regular checks are crucial to ensure your insulation remains effective. Look out for moisture, pest infestations, or any damage that could compromise its performance. Keeping the underfloor area dry is paramount, so address any leaks promptly. Remember, well-maintained insulation can last years, saving you money and hassle in the long run.
Conclusion: Choosing the Right Insulation
Selecting the right insulation for your mobile home is about balancing cost, effectiveness, and your specific living situation. Whether you go for the affordability of fiberglass batts, the durability of foam board, the airtight seal of spray foam, the reflective prowess of reflective insulation, or the dual benefits of insulated skirting, make sure it suits your needs and budget. After all, a well-insulated home is a happy home on wheels!
With the right insulation under your mobile home, you’ll be living the dream with comfort and savings to boot. So roll up your sleeves, do a little homework, and prepare to give your mobile abode the warm embrace it deserves.
