6. Engineered Wood (SmartSide)

Engineered wood, such as LP SmartSide, is made by bonding wood fibers with resins. It’s treated for moisture, decay, and termite resistance. It offers the beauty of wood with added strength.

This material is lighter than traditional wood and easier to install. It’s pre-primed for painting, allowing customization. Regular painting helps maintain its durability.

Engineered wood is a great middle-ground material. It offers solid protection with aesthetic appeal. It’s one of the most commonly used materials for shed walls.

Pros:

• Pre-treated
• Lightweight
• Paintable
• Looks like wood
• Durable surface
• Resistant to pests
• Easy to work with

Cons:
