James Hardie Began Selling Fibre Cement Siding Products in the United

James Hardie began selling fibre cement siding products in the United States in 1989 to leading builders,lumberyards,and home improvement centres.Even though ads guaranteed the product would not rot or crack for 50 years,many builders hated the product.It was heavy to install,and it showed every flaw in a bad framing job.In 1997,Hardie decided to run ads in traditional lifestyle magazines and emphasize the emotional appeal of houses made with strong,weather-resistant materials.Soon consumers began asking their builders or remodellers to use the product.Trade ads were used to explain how builders could take advantage of the interest created by the ads in lifestyle magazines.By 2000,the Hardieplank was the number-one brand siding in North America.James Hardie is now the third-most-recognized brand of building material in the world.
