Windows in Mobile Homes: Things You Need to Know

Windows do so much more than let in natural light and fresh air—they play a big role in your home’s comfort and energy efficiency. But they can also be one of the biggest culprits when it comes to energy loss and unwanted heat or cold. Whether you’re repairing, upgrading, or simply trying to make your windows more efficient, knowing the basics can save you time and money.

Let’s break it down and make it simple, using insights from John Krigger’s Your Mobile Home.

Windows: A Thermal Weak Spot

Compared to doors and walls, windows are the weak link when it comes to energy efficiency. Their large surface areas and low R-values make them a prime source of heat loss in the winter and heat gain in the summer.

Windows can cause energy and comfort problems in four key ways:

1. Temperature Transfer: Cold windows cool your home in winter, while hot windows heat it in summer.
2. Air Leaks: Poorly sealed windows let air sneak through, especially on windy days.
3. Convection Currents: Hot or cold window surfaces create air currents that affect your home’s temperature.
4. Solar Heat: Sunlight streaming through windows can overheat your home in summer.

While replacing windows can improve energy efficiency, the cost of new windows often takes many years to recoup through energy savings. That’s why repairing or maintaining your existing windows is often the best first step.

Types of Windows in Mobile Homes

Mobile homes have evolved over the years, and so have their windows. Here’s a quick rundown of the most common types:

• Jalousie Windows: Found in older homes (pre-1976), these windows are great for ventilation but not for sealing. Multiple glass panes open fully, making them the best for airflow but the worst for keeping out drafts.
• Awning Windows: Similar to jalousies but with fewer panes. They’re a better choice for keeping out air when closed.
• Sliding Windows (Vertical or Horizontal): Popular in the 1980s and 90s, these aluminum or vinyl windows open and close in tracks and often come with insect screens.
• Prime Windows: Fastened to the home’s exterior wall, these are the main windows in most mobile homes.

Storm windows are often added to improve insulation and comfort. They’re typically mounted on the interior of the window frame and can make a noticeable difference in cold climates.

Repair or Replace?

The decision to repair or replace your windows depends on several factors:

• The type and condition of the window.
• The time and cost involved in repairs.
• The appearance of the window and how it fits your home.

If your windows are leaky, poorly sealed, or damaged, here are some maintenance tips:

• Seal Gaps: Use putty tape or caulking to close any gaps between the window and the wall.
• Weatherstrip: Replace worn weatherstripping to reduce drafts.
• Repair Sashes: Make sure the sashes close completely without gaps larger than 1/16 inch.

If repairs won’t cut it, consider upgrading to newer, energy-efficient windows with better insulation and durability.

Reducing Energy Loss

You don’t have to replace all your windows to see improvements in comfort and efficiency. Try these simple strategies first:

1. Install Storm Windows: Interior storm windows are a cost-effective way to reduce heat loss in winter.
2. Add Shading: In warmer climates, shading your windows can block 50–80% of unwanted heat from the sun. Options include blinds, curtains, or exterior shading like awnings.
3. Control Condensation: Moisture on windows can be a problem in colder months. Lower your home’s humidity with ventilation or a dehumidifier, and ensure storm windows are airtight.

Choosing New Windows

If you’re ready to invest in new windows, here’s what to look for:

• Insulation: Double-pane windows with gas fills offer better thermal resistance.
• Frame Material: Vinyl or aluminum frames are durable and low-maintenance.
• Ease of Use: Sliding windows are practical and stay in place year-round.

Keep in mind that new windows alone won’t solve all energy problems, but they can be part of a broader strategy for improving your home’s efficiency.

Egress Windows

For safety, bedrooms in manufactured homes must have egress windows that meet the following criteria:

• A clear opening of at least 20 x 24 inches.
• An opening area of at least 5.7 square feet.
• A sill height no higher than 36 inches.
• A locking device no more than 54 inches from the floor.

Make sure any new or repaired windows in your home meet these important safety standards.

Takeaways

Windows in mobile homes may be a thermal weak spot, but with the right repairs, maintenance, or upgrades, you can improve your home’s comfort and efficiency. Whether you’re sealing gaps, adding storm windows, or investing in new replacements, small changes can make a big difference.
