Comparing the two

When comparing the cost of GAF vs. SmartSide siding, GAF siding prices are generally more expensive than SmartSide siding prices, in large part because of the materials used for manufacturing. GAF's fiber-cement products require special handling and gear to protect against airborne particles during installation. SmartSide products act and work like wood siding, and there are no special tools needed.
