VZB Z Flashing - 100 Pieces

VZB Z Flashing — Long-Lasting Water Penetration Protection for Vertical Surfaces

The VZB Z Flashing is a professionally engineered flashing solution designed to prevent water infiltration at critical transition points on exterior wall assemblies. Available in primed galvanized steel or color-matched aluminum, it is suited for contractors working on residential and commercial siding installations. Primary applications include window trim, band boards, panel intersections, and other vertical surfaces where moisture management is essential. The 8-foot standard length and optional hem configuration make it adaptable to a wide range of project requirements.

Technical Specifications

Available Variants

Unlike generic flashing products, the VZB Z Flashing is offered in both a primed galvanized steel option for field-painted applications and a color-matched aluminum option pre-coated with an exterior-grade paint system, eliminating the need for additional finishing on most standard siding and soffit color schemes. The proprietary coating on the primed version provides weather resistance while maintaining paint adhesion, giving contractors flexibility in how they finish the installation.

Key Features & Benefits

Dual Material Options

The VZB is available in primed galvanized steel or color-matched aluminum, allowing contractors to select the right material for their specific project finish requirements. The primed version accepts field-applied paint, while the color-matched aluminum arrives pre-finished for faster installation.

Proprietary Weather-Resistant Coating (Primed)

The galvanized steel primed version features a proprietary coating engineered to withstand harsh weather conditions. This coating also promotes paint adhesion, ensuring a durable finish bond when the flashing is painted on-site.

Exterior-Grade Paint System (Color Matched)

The color-matched aluminum variant is coated on both sides with a paint system specifically formulated for exterior applications. This dual-side coating provides consistent protection and appearance, reducing callbacks related to coating failure.

Hem Option for Enhanced Water Shedding

A hem is standard on all color-matched standard colors and available upon request on the primed version. The hem provides a finished edge that improves water shedding performance at the flashing termination point.

8-Foot Standard Length

The 8-foot standard length reduces the number of joints required on typical window and band board runs, minimizing potential leak points and speeding up installation.

Common Applications

Window Trim Flashing

Installs over window trim to direct water away from the window-to-wall interface, preventing moisture intrusion at one of the most common failure points in exterior wall assemblies.

Band Board Protection

Applied over band boards to shed water at floor-line transitions, protecting the structural framing below from water damage.

Panel Intersections

Used at siding panel intersections to bridge the gap between panels and prevent water from tracking behind the cladding system.

Vertical Surface Transitions

Suitable for any vertical surface transition where a durable, weather-resistant flashing is required to stop water penetration.
