PVC Mouldings for Exterior Applications
PVC mouldings are exterior-grade trim profiles designed to add architectural detail and create clean transitions across elements such as rooflines, windows, doors, and trim assemblies. Unlike wood, PVC mouldings resist moisture and will not rot, split, or warp over time, making them a durable, low-maintenance solution for exterior applications.
Available in a range of profiles, PVC mouldings provide flexibility in design while maintaining consistent performance across different trim applications..

PVC Moulding Applications
PVC mouldings are used across a wide range of exterior and moisture-prone applications, including:
- Crown moulding along rooflines and soffits
- Window and door casing for finished openings
- Decorative trim profiles for architectural detailing
- Transition mouldings between different exterior surfaces
PVC mouldings can also be used in high-moisture interior areas such as bathrooms and laundry rooms where traditional wood mouldings are more prone tomoisture damage and mold.
Benefits of PVC Mouldings
PVC mouldings provide consistent performance and durability in exterior conditions:
- Resistant to moisture, mold, and mildew
- Will not rot, split, warp, or cup over time
- Not susceptible to insect damage
- Maintains consistent shape and crisp profile details
- Stable material that installs and fastens predictably
- Low maintenance compared to traditional wood
- Can be left white or painted for custom finishes
PVC Moulding Profiles
PVC Crown Moulding
PVC crown moulding profiles are used at the junction of rooflines, soffits, and exterior wall assemblies to add architectural detail and create clean transitions. Profiles can be used individually or combined with other trim elements to build out more complex cornice and column capital designs.
Crown moulding installs using standard tools and fasteners and is available in a range of classical styles suited for both traditional and contemporary applications. The material maintains crisp profile lines over time without cupping, splitting, or moisture-related deterioration, making it well suited for exterior exposure as well as high-moisture interior areas such as bathrooms and laundry rooms.
Profiles are available in 12, 16, or 18 foot lengths depending on the profile dimensions and lengths are shown in each image.
PVC Sill & Detail Moulding
PVC sill and drip profiles are used to manage water around windows, doors, and cladding while creating clean transitions within exterior assemblies. These profiles are commonly used as brick ledges or water tables to separate different material veneers, while detail profiles can be used as base shoe, inside corner moulding, or to cover veneer joints and transitions.
Sill and detail profiles can be used as standalone trim elements or integrated into larger build-outs above windows, doors, and along roofline rakes. The material performs reliably in exterior conditions without cupping, splitting, or moisture-related deterioration and is suitable for ground contact applications.
Profile dimensions and available lengths are shown in the images for reference.
PVC Window & Door Casing
PVC casing profiles are decorative mouldings installed flush against walls, windows, and doors to create finished surrounds and clean architectural transitions. Profiles can be used individually or combined with other mouldings to build out more detailed window and door assemblies suited to both traditional and contemporary designs.
Profile dimensions and available lengths are shown in the images for reference.
Casing profiles install using standard woodworking tools and fasteners and maintain crisp profile lines over time without cupping, splitting, or moisture-related deterioration. The material performs reliably in exterior conditions, including high-moisture areas where wood casing would be more prone to damage.
Casing profiles are compatible with multiple siding types and can be used across a range of exterior assemblies. They can also be combined with sill and moulding elements to create complete window surround assemblies, as shown below.
PVC Window Surround Designs
PVC window surrounds are built using combinations of casing, sill, and trim profiles to create complete, finished assemblies around windows and doors. These designs add architectural depth and visual character to exterior elevations while simplifying installation compared to traditional multi-piece trim construction
Each surround shown uses standard PVC trim and moulding profiles, allowing for flexible design combinations that perform consistently across different exterior conditions without the maintenance concerns associated with wood.
