Deceuninck H Mullion, Colonial White, 3/4" x 16' PVC Trim Profile
This Deceuninck H Mullion is a 3/4 in. x 16 ft. H-shaped divider profile in Colonial White, sold as a single piece. Made from rigid PVC, it slips over the meeting edges of two panels or sheets to create a clean, finished seam in window, door and cladding assemblies. One 16 ft. length covers a full-height joint in most installations.
Key Features:
- H-profile joint cover: The H shape captures the edges of two adjacent panels, hiding the joint with a finished divider.
- Rigid PVC construction: Deceuninck PVC profiles resist rot, moisture and insect damage compared with wood trim.
- Colonial White finish: A Colonial White color integrates with white window, door and cladding systems.
- 16 ft. length: One 16 ft. piece spans most full-height joints without splicing.
- 3/4 in. profile: The 3/4 in. width suits the mating edges of Deceuninck panel and trim components.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
H mullions are the tidy way to close panel joints in clad assemblies; measure each run before ordering because profiles cannot be stretched. Cut with a fine-tooth blade, support the length while cutting, and let the profile, not sealant, carry the alignment. If your joint faces sustained direct sun, confirm expansion clearance at the panel edges so the PVC can move seasonally.
Wear eye protection and gloves when cutting PVC; chips and edges are sharp, and hot scrap should not be handled until cooled.
Finish your panel joints cleanly with the Deceuninck H Mullion in Colonial White, 3/4" x 16'.
