Top 3 Subfloor Choices for Mobile Homes

16 May Top 3 Subfloor Choices for Mobile Homes

When picking subfloors for mobile homes, choose wisely. You need strong materials that last, resist water, and fit your budget. Bad choices, like particleboard, can cause soft spots and expensive fixes—up to $10 per square foot! Strong options like plywood, OSB, and MGO board are better. Plywood resists water well, and OSB is cheaper at $1.40 to $3 per square foot. Choosing the right subfloor saves money and prevents future problems.

Cons of Plywood

While plywood is a strong and reliable choice, it does have some downsides you should know about.

• Moisture Vulnerability: Plywood can absorb water if it’s not treated or sealed properly. Over time, this can lead to swelling, warping, or even rot. If your mobile home is in a humid area, this could be a problem.

• Cost for High-Quality Options: Basic plywood is affordable, but higher-grade options like marine plywood or tongue-and-groove plywood can get pricey. If you’re on a tight budget, this might limit your choices.

• Surface Imperfections: Some types, like CDX plywood, have a rough surface. You might need extra work to smooth it out before installing flooring.

• Weight: Plywood is heavier than some other subfloor materials. This can make handling and installation a bit harder, especially if you’re working alone.

Tip: If you choose plywood for your subfloor, make sure it’s treated for moisture resistance and fits your budget.

When to Choose Plywood for Your Mobile Home Subfloor

Plywood works well in many situations, but it’s not always the best choice. Here’s when you should consider it:

1. Moderate Moisture Areas: If your mobile home is in a region with mild humidity, plywood subfloor materials like CDX plywood can handle the conditions. Just make sure it’s sealed properly.

2. Budget-Friendly Projects: Plywood is a good middle-ground option. It’s cheaper than MGO board but stronger than OSB. CDX plywood is especially affordable and durable.

3. Quick Installation Needs: Plywood is easy to cut and install. If you’re looking for a material that saves time, this is a solid pick.

4. Heavy Furniture or Equipment: Plywood’s strength makes it ideal for homes with heavy furniture or appliances. It won’t bend or crack under pressure.

Note: If your mobile home is in a very humid or wet area, you might want to look at marine-grade plywood or consider other materials like MGO board.

OSB: A Budget-Friendly Subfloor Material for Mobile Homes

What is OSB?

OSB stands for Oriented Strand Board. It’s a common material used for subfloors in mobile homes. OSB is made by pressing wood strands and flakes together with strong glue. These wood pieces often come from small trees like aspen or birch. The result is a tough, lightweight board that’s simple to use and install.

If you need a cheaper option, OSB is a good pick. A 4 x 8-foot sheet of 23/32-inch OSB costs about $16.50. That’s $3 to $5 less per sheet than plywood. When covering a whole mobile home, these savings can make a big difference.

Key Features of OSB

OSB has special qualities that make it a good subfloor choice. Here’s a quick look:

OSB panels are stable and keep their shape well. The outer layers have strands lined up along the panel’s length. The middle strands are placed randomly or across the width. This design makes OSB strong and long-lasting.

Pros of OSB for Mobile Homes

Why choose OSB for your mobile home floors? Here are the main reasons:

• Affordable: OSB costs less than plywood, helping you save money.

• Strong: It can hold heavy furniture and handle lots of foot traffic.

• Lightweight: It’s easy to move and install, even if you’re working alone.

• Water-Resistant: Many OSB panels have a wax layer to protect against water.

• High Quality: OSB is made without gaps or weak areas, ensuring reliability.

If you want a low-cost but dependable subfloor, OSB is a great option. It combines affordability with good performance, making it perfect for mobile homes.

Cons of OSB

OSB is affordable and strong, but it has some downsides:

• Moisture Sensitivity: OSB can handle some water but isn’t fully waterproof. If water gets into the edges, it can swell and weaken. This makes it less suitable for places with high humidity or leaks.

• Heavy Weight: OSB panels are heavier than other subfloor materials. This can make them harder to move and install, especially if you’re working alone.

• Rough Appearance: OSB looks unfinished and rough. While this doesn’t matter for hidden subfloors, it’s not ideal for visible areas.

• Not Great in Wet Areas: OSB lasts longer than particleboard but doesn’t do as well as plywood or MGO board in damp conditions.

Tip: Seal OSB edges and keep it dry to make it last longer.

When to Choose OSB for Your Mobile Home Subfloor

OSB works well in certain situations. Here’s when it’s a good choice:

1. Low Budget: OSB is one of the cheapest subfloor options. It’s great for big projects where saving money is important.

2. Dry Areas: OSB lasts a long time in places with little humidity. If your mobile home is in a dry area, it’s a solid choice.

3. Light Use: OSB is strong enough for most homes without heavy furniture or appliances.

4. Fast Installation: OSB is lightweight and easy to install, saving time and effort.

Note: If your mobile home is in a wet or humid area, consider using MGO board or marine-grade plywood instead.

Picking the right subfloor for your mobile home is important. It can save money, time, and prevent future problems. MGO board is the best option. It’s strong, blocks moisture, and is simple to install. Unlike drywall, MGO board is safer, tougher, and better for the environment. Here’s a comparison:

Plywood is also a solid choice. It’s tough and works well in areas with little moisture. If you need a cheaper option, OSB is a good pick. It’s not as strong as MGO board or plywood, but it’s fine for dry places.

Think about your budget, weather, and home needs before deciding. The right subfloor will keep your mobile home safe and comfortable for years.
