We've all seen some epic battles over competing products in which parts of the ad campaign relied on going after the competition. Pepsi vs. Coke, Chevy vs. Ford, or today's PC vs. Mac and I-Phone vs. Android are just a few. While those have played out on the national stage, home improvement product battles take place with the contractors, builders, or with you at your kitchen table. The current battle of paintable composite siding boards has given rise to quite the rivalry between LP SmartSide and James Hardie. These two really don't like each other; they make the Vikings/Packers rivalry look pretty tame in comparison. And like Vikings/Packers, the front line of this battle is taking place in the Twin Cities because this is one of the top remodeling and building markets in the nation.
Why Use Paintable Composite or Engineered Wood Boards?

After thousands upon thousands of houses were done in "maintenance-free" siding like aluminum, steel, and vinyl, a demand for more traditional looking paintable products started to build in the 90's and into the 2000's. Most customers wanted the wider 6" or 7" exposure to differentiate from all the 4" vinyl out there. However, these new products needed to perform much better than earlier hardboard products, which had the problem of swelling and falling apart in high moisture areas. Some were basically sawdust and glue. Customers also wanted to stay away from the expense and regular refinishing needed with real cedar.
Modern composite boards were the answer for millions of homeowners. They got the traditional look they wanted with a vastly improved resistance to moisture. One advantage of these boards over maintenance-free products comes when it is time to sell the house. A fresh coat of paint can make the product look brand new again if it had experienced some fading over time. Also, these types of products stand up much better to hail and other impact than vinyl, aluminum, or steel.
Hardie Takes Over

An Australian company, James Hardie, stepped in to the market with their "fiber cement" product and began killing it in the 90's. Many new neighborhoods were built with a Hardie covenant, meaning every house must be sided in Hardie. Building plans with more traditional looks were calling for Hardie every time. It could be purchased primed (to be painted on the house) or it could be ordered pre-finished with one of their "Colors Plus" colors. Despite some other fiber cement products on the market, like "Certainteed Weatherboards" or the Japanese "Nichiha," the term "Hardie Board" became known as the generic term for "Fiber Cement," much like "Kleenex." They were working with little competition, and the customers were loving the look of the product.
While contractors had complained about Hardie's service with certain warranty issues, they were in no position to switch to anything else. As a response to some of the delamination issues that came up in high moisture areas or as a result of it being installed incorrectly, Hardie re-formulated their product a few years back for the northern climate and named it HZ5. It has improved the overall performance of the product. Also, I have heard that the reps have been more receptive and helpful with warranty claims than they once were. Could the reason for this be that a certain competitor has been taking large bites out of its market share? Enter LP SmartSide.
Here Comes LP Smartside

LP (Louisiana Pacific) SmartSide came into the marketplace in 1997 with barely a blip on the radar. LP had just gone through the fiasco of their earlier Oriented Strand Board (OSB) siding product, Inner Seal, which had major problems. It was plagued with rot and swelling, and once that process started the paint would no longer hold. LP had to settle a class action lawsuit and resolve homeowners' claims. Obviously, the focus of their next siding panel would be resistance from moisture. They still use OSB product, but all of the wood flakes are coated in zinc borate beforebeing pressed into siding with MDI resins and marine waxes. The result? More than 7 billion square feet of siding sold and over 17 years of dependable performance. I've not had to deal with one warranty claim on this product.

The confidence in moisture resistance also shows in their install specifications. LP can be installed 1" up from where a roof line meets a wall; Hardie requires a 2" gap to maintain warranty. The 2" gap requirement leaves installers with a challenge to put something in that gap that looks better than exposed shiny aluminum flashing. Some paint the aluminum only to have it peel later. Others use a small trim board made of a PVC-heavy composite. The image to the right shows aluminum flashing in the gap from the roof line to the Hardie shakes.
