Overview of LP® SmartSide® and Hardie® siding

There is one thing in common between LP® SmartSide® and James Hardie®. The companies have brilliantly succeeded in their industry because both of them have introduced game-changing siding solutions at a certain point. That is an underlying reason why Hardie® fiber cement products alongside with LP® SmartSide® ones made of engineered wood have snatched the immense amount of market share.

Even so, it is still puzzling. Here are some other factors that you may want to consider when choosing between LP® SmartSide® and James Hardie® siding.

Company experience

While Hardie® has been producing its siding solutions for commercial and residential buildings for over 100 years, LP® SmartSide® has managed to enter the market a little more than 40 years ago. Therefore, the experience is in favor of the Australian company. Do not take that for granted though.


The ability of siding to withstand region-specific weather conditions, remain resistant to extreme temperatures and adequately protect the outer walls of a building against pests should be given priority when making your choice. Both Hardie® and LP® SmartSide® are known for providing highly durable planks. However, there are some differences in their structural integrity. Unlike its counterpart, engineered wood siding is treated with water-resistant waxes and adhesive resins, which create an extra protective layer against all impacts associated with weather. Yet, fiber cement products are far more effective in resisting fire damages.

Appearance and finish

Both manufacturers come up with a variety of colors for their siding products, making it easier for homeowners to improve their exterior design. You can choose any color and repaint those planks as you please. Besides, Hardie® siding comes pre-finished with a 15-year warranty so that you don’t need to deal with painting for a long time.

Installation and maintenance

The ease of installation and maintenance are one of the most serious Hardie® siding problems. Due to their heavy composition, these products are inferior to LP® ones in this regard. The thing is, engineered wood siding solutions require far fewer tools for cutting than those made of fiber cement. Besides, they don’t need to be carefully maintained, unlike Hardie® planks.


If you are about to start a home improvement project, it’s important to make sure you invest in reliable materials. It is a warranty that plays a crucial role in that matter. Both LP® SmartSide® and James Hardie® provide limited warranties but with different coverage periods. It is 50 years for the former and 30 years for the latter.
