Cladding vs. Siding: What’s the Difference?
Cladding and siding both cover the exterior walls of a building. Both protect against the weather, improve appearance, and add value to a home. But they are not the same thing.
The key difference is how they are installed. Siding is applied directly to the exterior wall. Cladding includes an air gap between the covering material and the wall. That air gap changes everything; it affects moisture management, insulation, durability, and cost.
This guide explains the real differences, compares performance across six dimensions, and helps you choose the right system for your home.

What Is Cladding?
“Cladding” is a type of siding system. It consists of the siding itself, which shields your home from rain, snow, and wind, and an air space between the siding and the outer wall that allows for drainage and ventilation. The air gap doesn’t contribute much extra insulation to your building, and the cladding may have its own layer of insulation underneath the air gap to better control temperature. The phrase is often associated with tougher siding materials such as brick and stone, but you can use any siding material as part of a cladding system.
| Pros | Cons |
| Less risk of mold | More expensive |
| Moisture protection | Harder to install |
| Better insulation | Less DIY friendly |
Best for:
- Homes in areas that see excessive rain or moisture.
- Maximizing building efficiency.
- Installing new siding without removing the old siding.
Pros of Cladding
Cladding includes an air space that helps dry any moisture that gets beneath your siding. This is good in locations where high humidity and heavy rainfall would otherwise be an issue for moisture trapping, mold growth, and wood decay. Wood siding in particular works well with cladding systems because wood siding may absorb moisture and keep it away from your structure without that ventilation.
The air gap adds a little bit of extra insulation, but you can also pair siding with an air gap and rigid insulation to make your house even more energy efficient. Keep the conditioned air inside and save on heating and cooling costs.
Cons of Cladding
Installation is more complicated, as cladding includes more than just adhesives or bolts, fastening your siding to your home. It’s more expensive since it takes longer to install and needs more supplies.
The more complicated install also means it’s not as DIY friendly. DIY is still an option, but you’ll have to pay more attention to make sure you’ve got enough spacing for ventilation and drainage. It’s better to hire a siding contractor near you to do the install.
What Is Siding?
Siding is simpler than cladding, with just the siding and often one layer below. You apply siding directly to your outside wall, typically over a basic weather barrier like house wrap, using adhesives or fasteners. It protects your home from the elements and provides a finished look, but does not provide any ventilation or insulation. The word is most often associated with softer siding materials, such as vinyl or wood.
| Pros | Cons |
| Simpler installation | No added insulation |
| Easier to DIY | More prone to mold |
| More affordable | Moisture issues |
Best for:
- Homeowners who want a more affordable way to finish their home’s exterior.
- Homes in areas where moisture and water exposure aren’t a major concern.
- Homes in more moderate climates.
Pros of Siding
Siding is a simplified type of cladding; it has no air gap or insulation, so it takes fewer materials and is faster to install. It is therefore cheaper in material, as well as in labor.
It’s also easy to do yourself with the simpler installation. With some patience and practice, you can install basic siding yourself; a siding pro will give you a cleaner look.
Cons of Siding
Siding does not insulate or provide an insulating air gap; it makes your home less efficient. Choosing siding over cladding may lead to increased energy expenditures, especially in harsh regions.
In places with high humidity and a lot of rain, basic siding solutions also make your home more susceptible to moisture problems, mildew, and wood decay. This is especially true if you go with a semi-permeable siding material like wood.
Cladding vs. Siding: Side-by-Side Comparison
| Factor | Siding (Direct-Applied) | Cladding (Rainscreen System) | Advantage |
| Installation complexity | Simple, fasten to the wall over the house wrap | More complex, requires WRB, furring strips, ventilation gaps, and detailed flashing | Siding |
| Cost | $3–$8 per sq ft installed | $6–$14 per sq ft installed | Siding |
| Moisture management | Limited, no drainage or drying path | Excellent, an air gap allows drainage and drying | Cladding |
| Mold risk | Higher in humid climates | Significantly lower | Cladding |
| Energy efficiency | No added insulation | Air gap + optional rigid insulation improves R-value | Cladding |
| Durability | Good in dry climates | Better in all climates, especially wet regions | Cladding |
| DIY friendliness | Easier for homeowners | Harder, professional install recommended | Siding |
| Appearance | Identical from the outside | Identical from the outside (wall is ~1 inch thicker) | Tie |

When to Choose Siding
Siding is the right choice when:
- Budget is the primary concern. Direct-applied siding costs roughly 30–50% less than a rainscreen cladding system using the same material.
- Your climate is dry to moderate. In areas with low humidity and infrequent heavy rain, the moisture management advantages of cladding are less critical.
- You plan to DIY. Attaching siding over house wrap is a manageable project for experienced DIYers. No air gap engineering is required.
- You are re-siding an existing home on a budget. Removing old siding and applying new material directly is faster and cheaper.
When to Choose Cladding
Cladding is the better investment when:
- You live in a humid or rainy climate. The ventilated air gap is the most effective way to prevent moisture from being trapped inside wall assemblies. This dramatically reduces mold, wood rot, and structural damage over time.
- You want maximum energy efficiency. Adding rigid insulation (such as XPS or mineral wool) behind the cladding can increase wall R-value by R-5 to R-10, reducing heating and cooling costs.
- You are building new construction. It is far easier and more cost-effective to install a rainscreen system during new construction than to retrofit one later.
- You are using wood or composite cladding. Wood absorbs moisture more readily than vinyl or metal. A rainscreen gap is especially important for wood and wood-composite materials to prevent rot and extend lifespan.
Common Cladding and Siding Materials Compared
The material you choose matters as much as the installation method. Here is how common options perform in both systems.
| Material | Best System | Cost per Sq Ft (material only) | Maintenance | Lifespan |
| Vinyl | Siding (direct) | $2–$5 | Very low | 20–30 years |
| Wood (cedar, redwood) | Cladding (rainscreen) | $5–$12 | High (stain/seal every 1–3 years) | 15–30 years |
| Fiber cement (e.g., Hardie) | Either | $5–$10 | Low–medium (paint every 10–15 years) | 30–50 years |
| Composite | Either (cladding preferred) | $6–$12 | Very low | 25–30+ years |
| Metal (aluminum, steel) | Either | $5–$15 | Low | 40–50+ years |
| Stone / Brick veneer | Cladding (rainscreen) | $10–$30 | Very low | 50+ years |
Why Composite Cladding Is Growing in Popularity
Composite cladding combines recycled wood fibers and plastic polymers. It looks like natural wood but does not rot, warp, or require painting. It resists moisture, insects, and UV fading with virtually zero maintenance.
EVODEK composite cladding uses capped co-extrusion technology, the same protective polymer shell used in capped composite decking. This shell blocks moisture penetration at the surface level. When installed as part of a rainscreen system, EVODEK cladding provides both the ventilated air gap and a moisture-proof surface layer, double protection against the most common cause of exterior wall failure.

FAQ
How to Tell If Your Home Has Siding or Cladding
You cannot tell from the outside alone. Both systems look identical once finished.
To check, carefully remove a small section of the exterior material near the base of a wall. If the material is attached directly to the sheathing or house wrap with no gap, you have direct-applied siding. If there is a visible air space (3/4 inch to 1 inch) created by furring strips between the exterior material and the wall, you have a rainscreen cladding system.
Is Stucco Considered Siding or Cladding?
Stucco is technically a form of cladding. A properly installed stucco system includes a waterproof membrane, a drainage layer or air gap, metal lath, and multiple coats of stucco material (scratch coat, brown coat, finish coat). This multi-layer assembly provides built-in ventilation and moisture management.
However, in everyday language, many homeowners and contractors simply call it “stucco siding.” Functionally, it behaves more like a cladding system than direct-applied siding.
What is cheaper: siding or cladding?
Siding is cheaper. Direct-applied siding typically costs $3 to $8 per square foot installed. Rainscreen cladding costs $6 to $14 per square foot installed due to the added furring strips, insulation, flashing, and labor. The extra cost is most justified in wet climates where moisture protection prevents expensive repairs later.
Can I install cladding over existing siding?
Yes. This is one of the advantages of a rainscreen system. You can install furring strips over old siding and then attach new cladding material to the furring strips. This creates the ventilated air gap without removing the old siding. Make sure the old siding is structurally sound and free of active rot or mold before covering it.
Does cladding add insulation to my home?
The air gap alone provides a small amount of thermal benefit. The real insulation gain comes from adding rigid insulation board (XPS, EPS, or mineral wool) between the wall and the furring strips. This can add R-5 to R-10 to your wall assembly, noticeably reducing heating and cooling costs.
