Henry Yellow Jacket

Henry Yellow Jacket is a high-performance, self-adhesive fiberglass-reinforced flashing membrane designed for sealing around windows, doors, and other critical transitions in above-grade wall assemblies. Engineered for reliable moisture management and long-term adhesion, this versatile product is trusted by contractors for both new builds and retrofits. It delivers robust protection against air and water intrusion, even under harsh Canadian weather conditions.

Featuring a flexible, durable construction with superior tack on a wide range of substrates, Henry Yellow Jacket enhances the air barrier system and improves the energy efficiency of your building envelope. Whether you’re working on residential siding or commercial cladding, this membrane provides a dependable seal to keep structures dry, airtight, and structurally sound.

Benefits

Weather-Resistant Seal: Provides a watertight, airtight barrier that prevents water and air from penetrating vulnerable openings.
Strong Adhesion: Adheres tenaciously to plywood, OSB, concrete, and other construction surfaces — even in cold weather conditions.
Reinforced Durability: Fiberglass reinforcement resists tearing, stretching, and UV degradation, making it ideal for job sites with frequent exposure.
Improved Energy Efficiency: Helps minimize air leakage, supporting compliance with modern building codes and improving thermal performance.
Simple Application: Self-adhered roll format eliminates the need for primers or fasteners, reducing installation time and labor costs.

Properties

FUNCTION: Acts as a flashing membrane and transition seal in air and weather barrier systems.
PRODUCT ROLE: Protects building envelope from air, water, and moisture infiltration.
BUILDING COMPONENT: Above-grade wall assemblies, door/window transitions, penetrations, and structural connections.

Overview

Henry Yellow Jacket serves as a critical line of defense in modern building systems, especially where water and air intrusion pose the greatest risk — around openings, joints, and complex transitions. The product’s aggressive adhesive bonds quickly, allowing for clean, efficient installation without the need for staples, nails, or mechanical fasteners.

Its fiberglass reinforcement adds structural integrity, enabling it to span gaps and resist wrinkling during installation. Unlike standard flashing tapes, which can degrade under UV exposure or lose adhesion in extreme temperatures, Henry Yellow Jacket maintains its performance year-round — a major advantage in climates like Toronto’s, where sudden temperature drops and wet conditions are common.

This flashing membrane also improves the overall integrity of air barrier systems by preventing drafts and thermal bridging. It supports energy-efficient construction and is an ideal choice for builders aiming to meet or exceed Canadian building codes, including SB-12 and other energy performance standards.

Developers, contractors, and renovation specialists all benefit from its balance of flexibility, toughness, and dependable adhesion. Whether sealing sheathing joints or detailing around penetrations, Henry Yellow Jacket ensures clean, effective transitions that stand the test of time.

Guide

Installation

Step

01

Ensure the surface is dry, clean, and free of dust, frost, or debris. For cold-weather installations (below 4°C), store the membrane in a warm area prior to use for optimal adhesion.

Step

02

Measure and cut the Henry Yellow Jacket roll to the required length. Peel off the release liner while applying pressure to bond the membrane to the surface, starting at the center and smoothing outward.

Step

03

When overlapping, maintain a minimum 2″ (5 cm) overlap between adjacent pieces. Use a hand roller to press the membrane firmly into place, especially at corners and edges.

Step

04

Seal any protrusions or irregular areas using compatible Henry sealants. For maximum performance, integrate with Henry’s full suite of air barrier components.

COMPARATIVE TESTING

Independent field and lab testing confirm that Henry Yellow Jacket outperforms traditional flashing tapes and generic peel-and-stick membranes in critical performance categories — including adhesion under cold conditions, UV resistance, tensile strength, and waterproofing integrity. Contractors report reduced callbacks and superior project outcomes when choosing Henry Yellow Jacket for flashing transitions.
