Selecting the Best Shutter Material
The material used to manufacture a plantation shutter influences much more than its finished look. It can influence moisture resistance, stability, weight, maintenance, finish and how suitable the shutter is for different rooms in the home. The three materials most often discussed when comparing shutters are timber, aluminium and PVC. Each has strengths, but they aren’t interchangeable. For most interior residential applications, we believe aluminium-reinforced PVC offers the best combination of finished look, durability, moisture resistance, stability and value. Timber remains an excellent choice when the natural look and grain of real stained wood is an important part of the design.

Why shutter material matters
Plantation shutters are expected to remain straight, operate smoothly and retain a consistent finish over many years. That makes the construction material especially important.
When comparing shutters, consider:
- How the material reacts to moisture.
- Whether long louvres are internally reinforced.
- Resistance to bowing and warping.
- How straightforward the surface is to clean.
- Whether the shutter is intended for interior or exterior use.
- Whether you want a painted finish or visible natural timber grain.
- Warranty and overall product construction.
A shutter should be judged as a complete engineered product instead of by the material name alone.
Timber shutters
Timber is the traditional plantation-shutter material and remains popular because of its natural finished look.
Real timber can be stained instead of merely painted, allowing the grain, variation and character of the wood to remain visible. This can create a warm, premium finish that works especially well in traditional interiors or rooms where natural materials are an important part of the design.
Timber can also be machined and finished in a wide variety of ways, making it a versatile material from an aesthetic point of view.
The main consideration is moisture. Timber is a natural material and can react to changing environmental conditions. Prolonged exposure to moisture can contribute to swelling, movement or warping, based on the timber, construction and finish.
For this reason, timber is typically not our first recommendation for moisture-prone rooms including bathrooms or areas where the shutter may regularly be exposed to water.
When should you select timber?
Select timber when you specifically want the finished look of real wood.
A stained timber shutter displays natural grain and variation that a synthetic material can’t genuinely reproduce. If that is an important part of the room, the additional cost of timber can make sense.
However, if you intend to select a painted white or neutral shutter, much of the visual reason for selecting timber disappears because the grain is covered by the painted finish.
Once fitted, there is very little visual difference between a high-quality painted PVC shutter and a painted timber shutter from normal viewing distance.
For most clients wanting a white plantation shutter, PVC therefore provides the more workable option.
Aluminium shutters
Aluminium is strong, lightweight and capable of being used in demanding applications. It is often associated with shutters designed for exterior, balcony or high-exposure environments where weather resistance and structural strength are especially important.
Aluminium doesn’t behave like timber and doesn’t absorb water, but exposed aluminium systems need appropriate coatings and design to protect against oxidation and corrosion, especially in harsh or coastal environments.
It also has a very different finished look and thermal behaviour from an interior PVC or timber plantation shutter. Aluminium readily conducts heat, so it can become hot or cold based on the surrounding conditions.
For a typical interior residential plantation shutter, aluminium is therefore a different type of solution instead of automatically being a superior material.
At National Trade Blinds we instead use aluminium where it provides the greatest benefit: hidden inside our PVC louvres as structural reinforcement.
PVC plantation shutters
PVC is an excellent material for interior plantation shutters because it combines a smooth, consistent finish with excellent resistance to moisture and straightforward maintenance.
Unlike natural timber, PVC doesn’t absorb water. This makes it especially workable for bathrooms, kitchens, laundries and other interior areas where humidity, splashes or regular cleaning may be a consideration.
The surface is also straightforward to maintain. Dust can typically be removed with a soft cloth and marks can be wiped away without the more specialised maintenance that some natural timber finishes can require.
PVC also produces a very consistent painted finished look. For clients selecting the classic white plantation-shutter look, this is one of its major strengths.
Aluminium-reinforced PVC
Not every PVC shutter should be assumed to have the same construction.
Our PVC shutters use an internal aluminium core to reinforce the louvres. This combines the moisture resistance and clean finish of PVC with additional structural strength from aluminium.
The reinforcement is especially important because plantation-shutter louvres are long, relatively thin components that need to remain straight while being repeatedly opened and closed.
The internal aluminium core helps increase rigidity and reduce the tendency for the louvre to bow or warp over time.
Rather than selecting between the advantages of PVC and aluminium, this construction uses both materials for the job each performs best: PVC for the exterior surface and aluminium for hidden internal reinforcement.
Are PVC shutters waterproof?
The PVC material used in our shutters is waterproof, which makes it especially suitable for moisture-prone areas inside the home.
That is different from saying the shutter is designed for outdoor use.
Our PVC plantation shutters are intended for interior installation only. They should not be fitted outside the home where the complete shutter, hardware and finish would be continuously exposed to exterior weather conditions.
For an interior bathroom, kitchen or laundry, however, PVC provides a major workable advantage over natural timber because the material itself doesn’t absorb moisture in the same way.
PVC vs timber
For most clients, the useful comparison isn’t merely “plastic versus wood”. It is a comparison between the finished look and workable performance of two different shutter systems.
PVC offers:
- Excellent moisture resistance.
- Easy cleaning.
- A consistent painted finish.
- Internal aluminium reinforcement in our shutters.
- Strong resistance to bowing and warping.
- Excellent suitability for kitchens and bathrooms.
- Typically better value for a painted shutter.
Timber offers:
- Genuine natural wood.
- Visible grain and natural variation.
- The ability to create beautiful stained finishes.
- A traditional premium finished look when the timber itself is intended to be seen.
If you want a stained natural-wood shutter, timber has a clear aesthetic advantage. If you want a painted white shutter, PVC will typically make more sense.
Painted white PVC vs painted timber
White remains one of the most popular plantation-shutter finishes because it produces a clean finished look and works with a wide variety of interiors.
Once timber has been painted white, the natural grain that makes real timber visually distinctive is largely hidden. This means the finished look of painted timber and a quality painted-look PVC shutter can be extremely similar once fitted.
That is why we typically don’t recommend paying the timber premium merely because timber sounds like the more expensive material.
If the final shutter is going to be white, consider the workable characteristics as well: moisture resistance, stability, cleaning, reinforcement and price.
On those criteria, aluminium-reinforced PVC is typically the stronger all-round choice.
Which material is best for bathrooms and kitchens?
For bathrooms, kitchens and other moisture-prone interior areas, PVC is the clear workable choice.
Steam, humidity and occasional splashes are conditions where natural timber needs greater care. PVC doesn’t absorb water and its smooth surface can be wiped clean easily.
The internal aluminium reinforcement in our PVC louvres also provides additional rigidity without changing the water-resistant exterior surface.
This combination makes PVC especially well suited to wet areas inside the home.
What about heat and insulation?
A plantation shutter produces another substantial layer between the room and the glass.
When the louvres are closed, the shutter can reduce direct sunlight entering the room and produces an additional air space at the window. This can help with comfort and light control, although shutters should not be considered a replacement for appropriate glazing or building insulation.
Material also influences how the shutter itself responds to temperature. Aluminium conducts heat readily, whereas PVC is much less thermally conductive.
For an interior shutter, this is another reason a PVC exterior is typically more comfortable and workable than a shutter manufactured entirely from aluminium.
Durability and maintenance
A good plantation shutter should not require complicated ongoing maintenance.
PVC is especially straightforward to live with because the surface doesn’t need staining, oiling or refinishing. Regular dusting and occasional wiping with a soft damp cloth is typically all that is needed.
Timber can also last for many years when used in the right environment and properly cared for, but natural materials and decorative timber finishes may require more consideration around moisture and cleaning products.
Regardless of material, durability also depends on the complete shutter construction. Louvre reinforcement, hinges, frames, panel design, manufacturing tolerances and hardware all matter.
This is why material should never be the only specification you compare.
So, what is the best material for plantation shutters?
For most interior residential applications, our recommendation is aluminium-reinforced PVC.
It provides the clean finished look clients expect from plantation shutters while being waterproof, straightforward to maintain and reinforced internally for greater rigidity. It is especially well suited to painted white shutters and moisture-prone rooms including kitchens and bathrooms.
Timber is the better choice when the material itself is part of the design — especially when you want a stained finish that showcases genuine natural timber grain.
Aluminium has valuable structural properties and is widely used in other types of shutter systems, but for our interior plantation shutters we believe those properties are better used as hidden reinforcement inside the PVC louvre instead of as the exposed shutter surface.
The simplest way to select is:
- Painted white or neutral interior shutter: select aluminium-reinforced PVC.
- Stained shutter with visible real timber grain: select timber.
That gives you the material whose advantages actually match the finished look and environment you want.
