The Difference Between HZ5 and HZ10 The HZ5 siding is designed to withstand damage from ice, snow, and freezing temperatures. Meanwhile, the HZ10 siding is formulated for areas where humid heat, salty sea air, and hurricane-force winds are present.

What does HZ10 mean?

The HZ10 system is engineered for areas with hurricane-force winds, salty sea air, and the brutal, humid heat of the southern half of the U.S. Specifically formulated for climate zones 6-10, the HZ10 boards resist cracking, splitting, rotting and swelling season after hot, humid, tropical storm season.

What is James Hardie HZ5?

HZ5® Fights Cold, Snow, Ice and Worry To ensure its beauty matches its durability, we’ve engineered the surface for higher performance, giving it superior paint adhesion and moisture resistance. In addition, we’ve added a drip edge to provide improved water management.

What is HardieZone?

They developed the HardieZone® System, which is based on eight individual climatic variables (think temperature, humidity, rain, snow, hail and topographical factors) that affect the long-term performance of siding. It was engineered with a reduced water absorption rate and more strength in freezing climates.

Can you pressure wash HardiPlank?

Tips for Cleaning Your Siding. There’s nothing like the look and feel of clean. Don’t use a high-pressure power washer to get the job done, as it turns out a low-pressure hose and a soft medium bristle (nonmetal) brush is the best way to remove dirt and debris from James Hardie® siding and trim.

How often does Hardie board need painting?

every ten to twenty years
What is Hardie Plank? Hardie Plank is a newer composite material made of concrete substrate. Hardie Plank is also called fiber cement siding. While it’s far heavier than aluminum, vinyl or wood, it is extremely durable and typically only needs a new paint every ten to twenty years for maintenance.

Where are the climate zones?

There are 4 major climate zones:

  • Tropical zone from 0°–23.5°(between the tropics)
  • Subtropics from 23.5°–40°
  • Temperate zone from 40°–60°
  • Cold zone from 60°–90°

What size sheets does Hardie board come?

HardiePanel vertical siding is 5/16 in. thick and is available in 4×8, 4×9 and 4×10 sizes.

Joint-flashing material must be durable, waterproof material that does not react with cement based products. Other products may also be suitable. James Hardie DOES NOT recommend using caulk or “H”-jointers for the butt joints of HardiePlank® siding with ColorPlus® technology.

Does Hardie board get mold?

It is highly susceptible to mold and mildew. Hardie Plank has many seams and the seams must be sealed or water can infiltrate behind the siding. It can crack and if it does, you must tear the whole wall down in order to replace just one plank. It is mold and mildew resistant.

How many climatic zones are in the hz5?

Using these factors we arrived at ten distinct climatic zones. Though different, we found common variables in certain regions, allowing us to engineer the HZ5® product line for zones 1 through 5 and the HZ10® product line for zones 6 through 10.

How does hz5 siding work in cold weather?

The HZ5 siding is designed to withstand damage from ice, snow, and freezing temperatures. To maintain a healthy balance of durability and beauty, its surface is engineered for superior moisture resistance and paint adhesion. It will also remain dimensionally stable during harsh weather conditions.

What are the zones in the hardiezone system?

Though different, we found common variables in certain regions, allowing us to engineer the HZ5® product line for zones 1 through 5 and the HZ10® product line for zones 6 through 10. The HZ5® product line is right at home in climates with freezing temperatures, extreme seasonal temperature variations, and snow and ice.

What makes James Hardie hz5 system so good?

The HZ5® product line is right at home in climates with freezing temperatures, extreme seasonal temperature variations, and snow and ice. To ensure its beauty matches its durability, we’ve engineered the surface for higher performance, giving it superior paint adhesion and moisture resistance.
