HardiZone® Siding System Tailored for St. Louis’ Weather
James Hardie has engineered their siding products specifically for specific regional climate zones and weather patterns. James Hardie scientists have taken into consideration eight distinct variables to consider regarding the exterior of your home. The relevant factors for St. Louis area are:
- Temperature Range
- UV radiation;
- Humidity
- Rainfall
- Snow
- Hail
- Topographical Features
- High Winds
These are factors that are seldom addressed by manufacturers of vinyl siding, aluminum siding, hardboard siding, stucco siding and other siding materials.
With the HardiZone System, James Hardie has added unique proprietary components to their product lines to further enhance the characteristics that you, as a homeowner, are looking for.
- The absorption rate of water has been reduced. Wind-driven rain penetrates through siding through a process called capillary suction. This has been greatly reduced through HardiZone technology.
- The surface has been fortified for superior paint performance and durability.
- The siding formulation has been modified to enhance Hardie’s strength in resisting the freeze/thaw cycle.
- The drip edge has been altered with an angled water jet edge cut to accelerate the water shedding process.
