The Pacific Northwest, particularly Spokane, WA, is known for its diverse climate—cold, snowy, and wet winters followed by hot, dry summers. For homeowners in mobile or manufactured homes, ensuring proper insulation is key to maintaining comfort, energy efficiency, and long-term structural integrity. These homes provide an affordable housing option, but without the right insulation, they can become costly to heat and cool.
Many mobile and manufactured homeowners focus on wall and roof insulation but overlook one of the most crucial areas: the skirting or “basement.” This part of the home is vital for protecting against extreme temperature swings, moisture intrusion, and energy loss. Without proper skirting insulation, homeowners may experience drafty floors, frozen pipes, and higher energy bills.
5 Reasons Why Skirting Insulation Matters
1. Energy Efficiency & Cost Savings
The underbelly of a mobile home is exposed to outside air, meaning it can significantly impact the home’s overall energy efficiency. Insulating the skirting helps to stabilize temperatures underneath the home, reducing the workload on heating and cooling systems and lowering energy bills.
2. Preventing Frozen Pipes & Damage
Spokane’s frigid winters can lead to frozen pipes, which can burst and cause expensive water damage. Skirting insulation acts as a protective layer, helping to maintain a more stable temperature under the home and preventing costly repairs.
3. Moisture & Mold Prevention
Mobile homes are susceptible to moisture buildup, especially in a damp climate like the Pacific Northwest. Insulating the skirting with moisture-resistant materials helps prevent condensation, reducing the risk of mold, mildew, and structural damage.
4. Enhanced Comfort
Have you ever noticed cold floors in the winter? That’s because cold air seeps in through the uninsulated underbelly. Adding skirting insulation helps keep the floors warmer in winter and reduces heat buildup in summer, leading to a more comfortable living environment year-round.
5. Pest Control & Structural Protection
An uninsulated and poorly sealed skirting can provide an entryway for rodents, insects, and other pests. Insulated skirting acts as a barrier, deterring critters from nesting underneath your home and causing damage.
What Triggers Homeowners to Consider Skirting Insulation?
Many mobile homeowners only consider insulating their skirting after experiencing problems such as:
- Skyrocketing heating or cooling bills due to heat loss and energy inefficiency.
- Frozen or burst pipes during cold winters.
- Cold floors and drafts making living conditions uncomfortable.
- Moisture buildup or mold growth, causing structural and health concerns.
- Pest infestations finding their way into the unprotected underbelly of the home.
Best Insulation Options for Mobile Home Skirting
- Spray Foam Insulation – Provides excellent air sealing, moisture control, and superior insulation value.
- Rigid Foam Board – Durable, moisture-resistant, and great for skirting applications.
- Fiberglass Batts – Budget-friendly and effective when installed properly with vapor barriers.
- Blown-In Insulation – Works well for filling gaps and increasing overall efficiency in enclosed skirting spaces.
If you own a mobile or manufactured home, skirting insulation is a crucial upgrade that can dramatically improve your home’s energy efficiency, comfort, and longevity. Many homeowners overlook this important step until they face expensive repairs or high utility bills. Taking proactive steps to insulate your skirting can save money, protect your home, and provide year-round comfort.
If you’re considering skirting insulation, consulting with a professional insulation contractor can help determine the best solution for your home and budget. Don’t wait to invest in insulation for a more efficient, comfortable home!
