Not only is mold unsightly, it can be harmful to your health. That's why, when you are designing or replacing siding on a home, the choices you make are so important. The siding material and siding installation method you choose can significantly reduce, or increase, your chances of mold inside your home. Choose wisely. Here's how.
From the millions of spores in the air to thriving colonies within the ground, mold is everywhere naturally. Inside and around the house are no different. Still, without proper food and moisture, most molds remain as spores.
Of course, keeping the outdoors dry and absent of food sources is impossible. And mold spores are always ready to start growing into a colony.
Fortunately, there are several premium options for siding material that are incredibly resistant to mold growth and decay. And a well-designed, well-ventilated rainscreen siding installation system will make it even better.
Often siding is installed with a "closed joint" system. A closed joint system uses furring strips with tongue and groove siding. T&G siding installation is longer to install but a lower upfront material cost. But you will need to be vigilante about checking for mold on your exterior since the air cannot freely travel up and out of a system like this.
Trapped moisture can lead to mold, of course, but also rot and decay of your siding system, your siding material, and your exterior walls. This damage can open opportunities for insects, as well. These are problems we all want to avoid in our homes.

Another option is the Climate-Shield® Rainscreen Siding System, a patented system designed to deter mold from forming on your exterior, which also keeps it out of your home's interior. Since Climate-Shield allows moisture to escape faster and in more places, moisture cannot be trapped where you can't see it.

The Climate-Shield Rainscreen system is a higher upfront investment in materials, but the well-designed ventilation of this Rainscreen system will give a lower maintenance and a higher return on investment over its lifecycle. Other time and money savers from Climate-Shield are:
Your siding choice can also determine your home's mold risk. If you are choosing a installation that prevents mold, you can add to your piece of mind with premium siding choices that are just as mold resistant. Let's take a look at the top hardwood siding and Pura NFC HPL laminate wood look siding.
High performing hardwoods' big advantage over other wood siding is the high density gives them an inherent resistance to mold, rot, and insects. This can increase your lifecycle return and lower your home maintenance. Not to mention a strong, gorgeous home exterior. Here are a few top options in premium high-density wood siding materials:
Ipe Wood Siding - With the highest natural fiber density of all tropical hardwoods, sustainably harvested Mataverde Ipe premium hardwood is used as a benchmark to compare the durability of other wood siding materials. With exotic graining and a light to medium brown color range, Ipe is an excellent choice for the strongest, most mold-resistant natural wood siding available.

More affordable than Ipe, it has a rich chocolate brown color range with interesting figuring and graining patterns. Mataverde Premium Machiche is FSC Certified to meet your project needs, and also has the very high mold and damage resistance of a high density hardwood.

Jatoba Wood Siding - Also known as Brazilian Cherry, Jatoba is another strong, tough, and long-lasting option that is also budget friendly. Jatoba boasts deep cherry red to brown tones with a coarser grain and dramatic patterns, making it a wonderful choice for a home exterior.
Cumaru Wood Siding - Cumaru has beautiful exotic graining and a reddish-brown color range that includes lots of variation.

If natural hardwood does not meet your design specifications, there's a beautiful wood look option in HPL laminate Pura NFC siding. If you prefer a more consistent, less varied color in your exterior design, Pura siding can provide that designer look combined with high moisture and damage resistance.
Installed using Rainscreen system, Pura NFC will have the same fantastic ventilation as wood sidings. Pura siding also offers you a strong, damage resistant material that does not bend, split or break in extreme weather.
Even with the right siding materials and installation, a homeowner can still do plenty to create a mold-resistant home from the inside, too.
