James Hardie Process and Color Technology

Innovation

James Hardie® siding products with ColorPlus® technology – a unified composition of advanced fiber-cement and baked-on pigment – combine the highest quality raw materials, proprietary manufacturing process and equipment, revolutionary paint technology and innovative color process to give homeowners an advanced siding solution for their homes.

James Hardie is the largest producer of fiber-cement siding in North America. The company controls its product from the initial mixing of the cement to final painting in one facility. To ensure that every board meets James Hardie’s standards, over 41 quality assurance checks are made throughout the manufacturing process and each batch of siding is also checked at three outside testing facilities to monitor long-term durability. In addition, most of the raw materials used to make James Hardie Siding are extracted and processed near each manufacturing facility.

Color Technology

James Hardie’s proprietary manufacturing process involves applying consistent, multiple coats of paint developed especially for our fiber-cement siding. Then, the paint is baked-on in a closely controlled factory environment. Our automated manufacturing process, constant quality monitoring and application of up to 50% more paint – compared to field-applied paint – provides the most consistent paint application at the optimal thickness. 

The James Hardie ColorPlus technology finish also represents a revolutionary breakthrough. The paint used in the process was made especially for James Hardie siding after more than four years in development and over 2,000 formulas tested. The end result is a durable, low-maintenance finish that lasts up to two times longer, has 30% better fade resistance and adheres up to 400% better than any other paint available.¹ 

ColorPlus technology finish is backed with a 15-year warranty that covers both paint and labor.² The finish warranty guarantees your color will not crack, chip or peel for 15 years.

Durability

Because long-term climate variables affect the performance of siding, James Hardie has engineered The HardieZone™ System based on ten distinct zones and the variables common among them. The greater Chicagoland area is within Zone 5 which means that the siding has been tested to maintain its integrity through snow and ice, weather changes and extreme humidity conditions. The surface is conditioned for higher performance, giving it superior paint adhesion and moisture resistance.
