FLEXTRIM #WM180 Flexible Brick Molding
This flexible brick molding is designed for very gentle curves and arches with an 80″ radius or larger. At 12 feet long and 1.25″ thick by 2″ wide, it’s suitable for long straight runs and curved transitions. It won’t warp, rot, or crack in high moisture environments. Best for projects with gradual arches where standard straight molding would be insufficient. Better for curved applications than rigid trims.
Best for: Interior or exterior uses requiring a flexible solution to cover door or window edges with gentle curves.
Limit: Not intended for half-round or very tight arches; use other options for tight curves.
FLEXTRIM #180 Flexible Brick Molding
This pre-curved molding is specifically designed to fit half-round arches with diameters from 34″ to 40″. It’s a complete curved piece that reduces on-site bending. Best for exterior arches and interior transitions where a consistent half-round look is desired. Choose this if you need a ready-made curved section.
Best for: Half-round door or window arches where a dedicated curved profile is preferred.
Limitation: Not suitable for eyebrow arches or very large custom arches outside the specified diameter range.
Novabright Precurved Flexible Casing Molding 3/4” THK
This polyurethane-based molding arrives pre-curved to fit half-round arches 34″ to 40″ in diameter. The 3/4″ thickness and 3-1/2″ width provide steady coverage around archways. It is designed to resist moisture, heat, and typical outdoor conditions, with air pockets on the back for stronger adhesion. Best for archways needing a strong, curved trim that installs with standard tools. Better for arched openings needing efficient installation.
Best for: Archways where pre-curved performance and moisture resistance matter.
Caution: Air pockets on the back exist; follow factory guidance for adhesive use.
Novabright Precurved Flexible Casing Molding 1.25” THK
With a thicker 1.25” profile, this pre-curved half-round PU trim covers larger arch gaps while maintaining a streamlined look. It’s designed for exterior and interior use, offering strong resistance to moisture and temperature fluctuations. This option suits wider arches or when a more substantial casing is desired. Choose this for a bolder arch profile.
Best for: Wider arches or when a more prominent trim line is preferred.
Limitation: Slightly heavier than thinner profiles; ensure door/frame fit accommodates the thickness.
Buying Guide
What material should you choose?
PVC trims are affordable, moisture-resistant, and easy to cut. Polyurethane trims offer superior rigidity, better edge definitions, and strong adhesion for curved arches. Choose PVC for quick installs and low maintenance, PU for arched or decorative needs.
Do you need pre-curved or flexible molding?
Pre-curved molding is ideal for half-round arches and fixed curves. Flexible molding accommodates gentle curves, longer runs, and uneven walls. For precise arch sizes (34″–40″ diameters), pre-curved options simplify installation.
How important is installation ease?
If speed matters, lean toward kits with pre-sized sections and minimal cutting. For complex openings, flexible or pre-curved pieces reduce on-site bending and gaps. Always plan for weatherproof sealing at the frame edges.
What about weather resistance?
Exterior trims should resist moisture, temperature swings, and pest exposure. PVC trims excel in damp environments, while polyurethane trims provide strong durability for intricate arches. Confirm compatibility with your door type and climate.
How to measure and plan?
Measure door rough opening width and height, plus any arch diameter. For arches, confirm diameter (34″–40″ is common) and choose a matching curved profile. Prepare for potential corner joints at door jambs and verify nail or adhesive requirements with each product.
