LP SmartSide vs James Hardie Siding

LP SmartSide vs James Hardie Siding

Which Siding Product Is Best?

So, you have come to the conclusion that your home needs new siding. Now if you could only decide what type of siding to go with! If you want a different look that comes with the “maintenance free” types of siding like vinyl, then you may be looking for a composite board solution.

Composite Siding Products

Today, composite board products have come a long way from the glue and sawdust version of the early 90’s. Not only do they hold up to harsh weather conditions and impact better than vinyl products, they can be given a new fresh look by adding a coat of paint.

The two main contenders for this market are LP SmartSide and James Hardie. This month’s blog post we would like to show you both the pros and cons of these two siding products and also share our professional opinion on which siding we think would best serve you.

LP SmartSide

Also known as Louisiana Pacific SmartSide, this siding is an Oriented Strand Board (OSB) product made up of strands of wood that are coated with a resin binder and then compressed to create a board of incredible strength. SmartSide products are treated with LP’s SmartGuard zinc-borate treatment to protect against wood rot and termites.

A special water-resistant wax is used to coat each fiber of wood for an enhanced durability in rainy and humid environments. With LP SmartSide you can also customize and choose what color/design you would like to go with.

Now that you know what LP SmartSide is made of, check out this list of pros and cons:


  • Durability
  • Variety of styles
  • Long-lasting warranty
  • Affordable
  • Easy to use
  • Environmentally safe


  • Labor intensive during installation
  • Since it is wood, it can burn
  • Does require maintenance

James Hardie Siding

Commonly known as fiber cement siding, this product is made up of water, wood pulp, sand, and Portland cement. James Hardie products have set the standard for fiber cement siding and the terms “Hardie Board” or “Hardie Plank” have become synonymous with “fiber cement” products.

James Hardie siding is generally used as an alternative to using real wood for siding, because it is able to mimic the look of just about any siding material. Because cement is a main ingredient in its construction this product also is extremely durable and resistant to rot and termites.

Let’s take a closer look at the pros and cons of this siding:


  • Durability
  • Fire resistant
  • Storm resistant
  • Variety of styles
  • Pre-finishing options
  • Cost effective alternative to wood


  • Maintenance
  • High-costs
  • Labor intensive during installation
