What's the most popular James Hardie siding? 

Need help deciding what type of siding and size to order? We asked one of our pros to tell us what his customers like and here's what he said:

Devon Anderson, Brennan Enterprises
HardiePlank - Select Cedarmill in 8-1/4 in. boards with 7 in. exposure.

"The majority of James Hardie jobs that I spec are for HardiePlank with the Select Cedarmill texture. Homeowners really like the wood grain texture of the Cedarmill. Occasionally, homeowners will ask for the Smooth plank if they want something more modern but it’s really rare, most want what is most popular and that’s the Cedarmill for my customers. We usually order the 8-1/4 in. board that has a 7 in. reveal."
