PVC mouldings and trims are becoming increasingly popular across Perth and Adelaide builds — and for good reason. They offer durability, moisture resistance, and a clean finish without the maintenance issues that come with traditional timber trims.
Whether you’re working on a residential build, renovation, or commercial fit-out, understanding where and how to use PVC trims can improve both performance and aesthetics.
—What Are PVC Mouldings and Trims?
PVC (polyvinyl chloride) mouldings and trims are lightweight plastic profiles used for finishing edges, corners, and transitions in construction.
- Water-resistant and non-rot
- Lightweight and easy to install
- Low maintenance compared to timber
- Consistent finish with no warping
They are commonly used in areas where moisture or wear is a concern.
—Why Builders Are Switching to PVC Trims
Traditional timber trims have limitations — especially in Australian conditions. PVC trims solve many of these issues.
- No swelling or warping in humidity
- Resistant to mould and moisture
- Longer lifespan in wet areas
- Cleaner, more consistent finish
This makes them ideal for both internal and external applications.
—Common Uses for PVC Mouldings and Trims
Internal Corners
PVC internal corner trims provide a clean finish and protect plasterboard edges.
- Used in walls and ceilings
- Improves durability in high-traffic areas
External Corners
External corner trims protect exposed edges from damage.
- Ideal for hallways and commercial spaces
- Prevents chipping and wear
Wet Areas
PVC trims are perfect for bathrooms, laundries, and kitchens where moisture is present.
- Won’t absorb water like timber
- Maintains shape over time
Often used alongside materials like: Fibre Cement
—Expansion Joints
Expansion trims allow for movement in materials, reducing cracking.
- Used in long wall runs
- Important in temperature-variable environments
Shadowline & Architectural Finishes
PVC trims are also used for modern design features like shadowline finishes.
- Creates clean, minimal lines
- Popular in contemporary builds
