Not sure which one to pick?

A brickmould is an exterior trim that frames your window or door where it meets the outside wall.
It provides both aesthetic appeal and structural protection—offering a clean, finished look while sealing the gap between the window frame and the exterior cladding.

Brickmoulds help prevent water infiltration, protect insulation, and improve long-term durability—especially important in Canadian climates.

When and Why Brickmoulds Are Used

Brickmoulds are commonly used in:

Brick-to-brick installations (typically in full-frame window replacements)
New construction projects where the window or door is installed before exterior finishes
Retrofits where old brickmoulds are replaced for a tighter seal or updated appearance

They act as a transition piece between the window or door and the wall—helping align the unit properly while providing a flush edge for fastening and sealing. They also enhance curb appeal by creating a consistent, architectural outline.

Features & Benefits

Made from 100% virgin uPVC—same maintenance-free material as IRIS windows and doors

Available in multiple profiles and sizes for every style

Choosing the Right Brickmould

New Construction? Use plank or nail fin brickmoulds for structural fastening and clean installation.
Retrofit Install? Use cap brickmould or sill nosing for minimal disruption to exterior finishes.
Vinyl Siding? Choose BMJ J brickmould for an integrated siding channel.
Custom Shapes? All IRIS vinyl brickmoulds can be bent to match shaped or arched windows.

💡 Pro Tip

The presence of a nail fin typically indicates a new construction window. Nail fins are fastened directly to the wall framing before siding or brick is applied—ensuring stability and performance from the ground up.

Note: All IRIS brickmoulds are manufactured in-house and color-matched to your window or door for a seamless, professional finish that lasts.
