FlashLock Vapour Open Flashing Tape 60mm x 30m

FlashLock Vapour Open Flashing Tape is a high-performance seaming and flashing tape designed to create durable, airtight and weatherproof connections within the building envelope. Engineered for sealing overlaps in vapour permeable membranes and flashing around windows, doors and service penetrations, it provides long-lasting protection while allowing trapped moisture vapour to escape.

By combining outstanding weather resistance with vapour permeability, FlashLock helps maintain the integrity of modern wall systems, reducing the risk of moisture-related damage while improving the overall performance of the building envelope.

Whether you’re constructing a new home, completing a commercial project or upgrading an existing structure, FlashLock delivers dependable sealing performance in demanding Australian conditions.

Engineered for Airtight and Weatherproof Seals

FlashLock has been specifically developed to create secure external seals where reliable weather protection is essential.

It is ideal for:

• Sealing overlaps in vapour permeable membranes
• Flashing around windows
• Flashing around doors
• Sealing service penetrations
• Wall junctions
• Building envelope connections

Its advanced design creates an airtight and driving rain-resistant seal, helping protect vulnerable junctions from air leakage and water ingress.

Vapour Open for Effective Moisture Management

Modern buildings require products that not only prevent water entry but also allow internal moisture to escape.

FlashLock’s vapour-open construction allows trapped moisture vapour to diffuse through the tape while maintaining a weather-tight seal. This helps reduce the likelihood of condensation build-up, mould growth and timber decay within wall systems.

The result is a healthier, more durable building envelope that performs efficiently throughout its lifespan.

FlashLock helps:

• Reduce trapped moisture
• Prevent water ingress
• Improve building durability
• Support energy-efficient construction
• Protect wall systems from condensation damage

High Tack Acrylic Adhesive for Lasting Performance

FlashLock features a premium high tack acrylic adhesive that provides excellent long-term adhesion to many common building materials.

It bonds securely to:

• Timber framing
• Vapour permeable membranes
• Rigid air barriers
• Common construction substrates

The advanced adhesive system is designed to maintain reliable performance over time, even in demanding Australian construction environments.

Tough Enough for Australian Building Sites

Construction products need to withstand challenging site conditions.

FlashLock features a robust puncture-resistant fleece backing that improves durability during handling and installation while helping resist damage on-site.

Its wide operating temperature range also allows dependable performance across changing Australian climates.

Service temperature:

• -10°C to 80°C

This makes FlashLock suitable for projects exposed to both cold winter mornings and extreme summer temperatures.
