Choosing a Wall Moulding Material
There are four materials commonly used for moulding: wood, PVC, MDF and polystyrene. Below we’ll explore the characteristics of each type:
- Wood moulding offers a high-end look that's ideal for traditional homes. It can be painted or stained for a fully customizable look. Though it’s durable and can typically last for years, it’s not recommended for bathrooms as humid conditions can cause wood to warp.
- MDF is a more affordable wall moulding option. It typically comes primed and ready for paint. MDF is less susceptible to warping compared to wood.
- PVC is designed to withstand moisture, making it a good moulding choice for bathrooms, laundry rooms and other areas prone to moisture. It’s considered low-maintenance and is insect-repellant. PVC can be painted with 100% latex paint.
- Polystyrene moulding is a lightweight, affordable moulding type. It’s a good choice for quick DIY upgrades but doesn’t offer the durability of other moulding types.
Wall Moulding Types
Wall moulding can be purely decorative or functional, and there are many types of wall moulding to choose from. Learn more about each type below.
Baseboard Moulding
Baseboards serve both aesthetic and functional purposes in interior spaces. Installed along the bottom edge of walls where they meet the floor, baseboards create a polished transition between vertical and horizontal surfaces, enhancing a room's appearance. They can also shield wall surfaces from any impact caused by furniture movement, foot traffic or cleaning activities like vacuuming.
Casing
Casing is used to frame doors and windows to cover the gap between the frame and the surrounding drywall. This type of moulding creates a clean, finished look by framing these openings with square or rectangular profiles that complement the style of the room. Beyond its practical role of concealing rough edges, casing adds visual interest and depth to doorways and windows.
Crown Moulding
Crown moulding is a classic architectural feature that has maintained its popularity. This decorative trim is installed where the walls meet the ceiling, creating a seamless and sophisticated transition between the two surfaces. From sleek to ornate, crown moulding is available in many styles to suit a variety of home styles.
Chair Rail Moulding
Originally designed to protect walls from chair backs, chair rail moulding has evolved into a versatile decorative element. Typically installed three feet above the floor level, aligning with the height of most chair backs, this moulding type creates a visual divide on walls. Beyond its practical origins, chair rails have become a popular way to add architectural interest and define the proportions of a room.
Beadboard
This distinctive wall treatment is characterized by a series of narrow, vertical planks with rounded grooves or beads between each board. This textured paneling originated in farmhouse-style homes but today, it’s a versatile option used in many home styles. In addition to adding texture and dimension to rooms, beadboard is ideal for protecting walls from scuff marks from furniture and foot traffic.
Square & Lattice Moulding
Square and lattice moulding are two different types of moulding but they’re typically grouped together because of their flat surfaces. Square moulding is typically thicker and wider than lattice moulding. It’s popularly used in Craftsman-style homes to create board and batten walls. It’s also commonly used as a baseboard material and for window and door casings.
Lattice moulding is commonly used to create geometric wall patterns. It can also be used as decorative trim for doors, walls or built-ins. It’s thin, narrow and flat with a rectangular profile, typically about ¼-inch thick.
Wall Moulding Accents
When using moulding, accents can be used to complete the look. From ceiling medallions and corbels to rosettes and plinths, below are some popular moulding accents to enhance the overall look of moulding.
Ceiling Medallions
Ceiling medallions install on ceilings around light fixtures and ceiling fans. They can help conceal imperfections on the ceiling where a fixture is installed and highlight the fixture, adding sophistication.
Crown Moulding Corner Blocks
Crown moulding corner blocks are decorative accents that install in wall corners where crown moulding meets, typically at the ceiling corners of a room.
Corbels
Corbels look like brackets and install under shelves, counters and mantels. Originating as a structural feature, corbels are now mainly a decorative feature. Choose from load-bearing or non load-bearing depending on how you’ll use them in your space.
Rosettes
Rosettes are purely decorative blocks that are used at corners where moulding meets. Popular for use around door and window casings, they’re perfect for enhancing ceilings, walls and existing moulding.
Plinths
Plinths serve as a base or support for columns, moulding and other trim. They provide a smooth transition between baseboards and narrow door trim.
Window & Door Headers
Window and door headers, also called crossheads, are placed at the top of windows, doorways or large entryways to enhance these spaces. They easily install with either adhesive or nails.
