Can You Insulate a Mobile Home?

Mobile homes are popular throughout Southwest Florida due to their affordability, flexibility, and coastal lifestyle appeal. However, one of the biggest concerns for mobile homeowners is maintaining consistent indoor comfort—especially in Florida’s hot, humid climate. The good news? Yes, you can insulate a mobile home, and doing so can dramatically reduce energy bills, improve comfort, and extend the life of your HVAC system.

At Koala Insulation of Southwest Florida, we specialize in custom insulation solutions for all types of homes, including mobile and manufactured homes. Whether you’re dealing with drafts, moisture issues, or high energy bills, upgrading your mobile home’s insulation is a smart investment.

Why Insulation Matters in a Mobile Home

Unlike traditional site-built houses, mobile homes are often constructed with thinner walls, limited underfloor protection, and minimal attic insulation. This means they are more susceptible to:

• Heat gain during hot summer months
• Heat loss during cooler nights or winter cold spells
• Drafts and poor indoor air quality
• High cooling and heating costs
• Moisture and condensation problems

Without proper insulation, mobile homes can quickly become uncomfortable and inefficient. That’s where Koala Insulation of Southwest Florida steps in—helping you upgrade your insulation to meet Florida’s unique climate demands.

Benefits of Insulating a Mobile Home

Adding insulation to your mobile home offers a wide range of benefits, including:

1. Lower Energy Bills

Insulation helps regulate indoor temperatures, which reduces the workload on your heating and cooling system. Most homeowners see an average energy savings of 15–25% after upgrading insulation.

2. Better Indoor Comfort

Say goodbye to hot spots, chilly drafts, and uneven temperatures. Insulation creates a thermal barrier that keeps indoor air consistent and comfortable.

3. Moisture and Mold Control

In Florida’s humid climate, moisture control is crucial. Proper insulation helps prevent condensation and mold growth, especially in the floors and walls of mobile homes.

4. Noise Reduction

Insulation also acts as a sound barrier, reducing outdoor noise and creating a quieter living environment inside your mobile home.

5. Increased Home Value

Improving energy efficiency and comfort makes your mobile home more attractive to potential buyers and can enhance resale value.

Key Areas to Insulate in a Mobile Home

To get the most benefit from insulation, it’s important to insulate the right areas. At Koala Insulation of Southwest Florida, we assess your mobile home to determine where energy loss is occurring and recommend the best solutions.

1. Underbelly (Floor Insulation)

The underside of your mobile home, also known as the underbelly or crawl space, is one of the most important areas to insulate. Without insulation here, cool air escapes during summer and moisture can accumulate. We use rigid foam board or closed-cell spray foam to insulate and protect this area from both heat and humidity.

2. Walls

Most mobile home walls are thinner than traditional homes and contain minimal insulation. Blown-in cellulose or fiberglass insulation can be added through small access points to increase wall R-values without removing drywall.

3. Roof and Ceiling (Attic Space)

Even in mobile homes without traditional attics, there is space between the roof and ceiling that can be insulated. We often use blown-in fiberglass or spray foam in this cavity to prevent heat from penetrating the living area below.

4. Ductwork and Air Sealing

In many mobile homes, ductwork runs beneath the home and is exposed to extreme heat and moisture. Insulating and sealing ducts can prevent energy loss and improve HVAC efficiency.

5. Windows and Doors

Although not traditional insulation, upgrading weatherstripping and adding storm windows or energy-efficient doors can help keep conditioned air inside and block outdoor heat.
