Product Overview
Tyvek Double-Sided Acrylic Tape with a 50mm width supplied on a 25m roll is a high-tack bonding tape designed for secure joining of Tyvek membranes and vapour control layers within the building envelope.
Featuring a reinforced carrier with acrylic adhesive on both sides, it creates a permanent bond between overlapping sheets, ensuring full airtight and watertight continuity.
The tape delivers excellent adhesion under site conditions and remains flexible for easy installation on irregular surfaces.
The 50mm width provides controlled coverage for joint bonding where precision alignment is required.
Features & Benefits
- Double-sided adhesion: Bonds two membrane layers together for continuous airtight and watertight performance.
- High-tack acrylic adhesive: Delivers fast, reliable bonding in a range of site temperatures.
- Durable and flexible: Reinforced carrier ensures consistent contact without tearing or deformation.
- Weather-resistant performance: Maintains adhesion under UV exposure and thermal variation.
- System compatibility: Fully approved for use with Tyvek breather membranes and vapour control layers.
- Ease of application: Simple peel-and-stick liner for quick on-site bonding.
- Permanent seal: Ensures long-term joint integrity within the Tyvek envelope system.
- Width specification: 50mm width suited to precise bonding of laps and narrow joints.
Applications
- Membrane joint bonding: For secure attachment of Tyvek membrane overlaps and joints.
- Air and vapour barrier sealing: Provides airtight connection between VCL sheets and adjacent materials.
- Roof and wall detailing: Suitable for internal and external interfaces requiring long-term adhesion.
- Service penetrations: Ideal for sealing around fixings, ducts, and conduits to prevent air leakage.
Installation Guidance
- Surface preparation: Surfaces must be clean, dry, and free from contamination.
- Application process: Remove release liner progressively and apply firm pressure to ensure complete contact.
- Temperature range: Apply between +5°C and +40°C; serviceable between −40°C and +100°C.
- Alignment: Use steady, even tension to prevent wrinkles or trapped air.
- Storage: Store flat, dry, and protected from sunlight at moderate temperature.
Compliance & Performance
