Hardiflex for Exterior Walls: Pros and Cons

When considering durable and weather-resistant exterior walls, Hardiflex is a popular material. If you’re willing to invest in the right finishing and care, Hardiflex can be an excellent alternative to wood or other traditional wall materials. Why is this so? Let's find out.

Hardiflex for your exterior walls? Here's Why

Hardiflex is a fiber cement board composed of cellulose fibers, Portland cement, sand, and water. It's engineered to be strong, resistant to fire, and capable of withstanding rain, humidity, and heat.

But how does it hold up when used outside? Let’s take a look at its key advantages and drawbacks.

Pros of Using Hardiflex for Exterior Walls

Weather Resistance

Hardiflex stands up well to rain, humidity, and heat, so it's the ideal material choice for the Philippines’ tropical climate. Unlike wood, it won’t warp or rot due to moisture exposure.

Fire Resistance

One of Hardiflex's significant benefits is its non-combustibility, which lowers the risk of fire damage. If safety is a priority, this material is worth considering.

Termite-Proof

Unlike wood, Hardiflex is impervious to termites, making it a smart investment in areas vulnerable to pest problems. 

Low Maintenance

Hardiflex requires less maintenance than traditional wood or plywood. A good coat of waterproof paint is usually sufficient to keep it looking good and protected from the elements. 

Lightweight and Easy to Install

Compared to concrete or brick, Hardiflex is lighter and easier to handle. It can be cut and shaped using basic tools, which makes it favorable for both DIY enthusiasts and contractors.

Smooth and Versatile Finish

Hardiflex can suit any wall finish, whether you're aiming for a modern smooth look or a textured design. You can paint, render, or tile it for a customized appearance. 

On the other hand, here are some cons to consider: 

Needs Proper Waterproofing:

Hardiflex isn't 100% waterproof on its own. If it isn't sealed or painted properly, moisture can seep in and cause damage over time. Proper waterproofing is needed.

Hardiflex is Not durable:

It can crack or break under heavy force.If you need a wall to withstand significant impact or load, concrete or brick may be better choices. 

Requires a Sturdy Support Frame:

Unlike concrete walls that can stand alone, Hardiflex needs a framework of steel or wood for support, which can increase installation costs and requires precise framing for stability.

Paint and Finishing Required:

To ensure Hardiflex lasts outdoors, you'll need to apply quality exterior paint and sealant, which adds to the initial expense and necessitates regular upkeep. 

If you choose Hardiflex for your exterior walls, here are some best practices to enhance its durability and performance:

• Use waterproof paint and sealants that are of high quality to guard against moisture.
• Ensure proper ventilation to prevent moisture buildup behind the Hardiflex panels.
  
• Install it on a sturdy frame, ensuring that it's properly anchored and resistant to rust or rot.
• Inspect for cracks and reseal them periodically to maintain structural integrity.
• Whenever possible, place Hardiflex walls under eaves or covered areas to minimize exposure to direct water.

In conclusion, Hardiflex can be a strong, cost-effective, and versatile option for exterior walls if installed and maintained correctly. It's particularly appealing to homeowners seeking fire-resistant, termite-proof, and lightweight materials suitable for the Philippine climate. However, ensure you address waterproofing, have a solid frame, and commit to regular maintenance for long-lasting performance. If you’re willing to invest in the right finishing and care, Hardiflex can be an excellent alternative to wood or other traditional wall materials.
