Product Overview
Tyvek Single-Sided Acrylic Tape with a 75mm width supplied on a 25m roll. A high-performance sealing tape engineered for use with Tyvek breather membranes and vapour control layers.
Manufactured with a UV-resistant acrylic adhesive and a strong Tyvek HDPE backing, it delivers a durable, airtight, and watertight seal at overlaps, penetrations, and junctions.
The high-tack adhesive forms a permanent bond to membranes, timber, and metal substrates even in low-temperature conditions.
The 75mm width provides secure coverage of membrane laps and junctions, ensuring long-term building envelope integrity and energy efficiency.
Features & Benefits
- Airtight and watertight seal: Provides a reliable barrier against air leakage and moisture ingress at laps and junctions.
- UV-resistant adhesive: Maintains adhesion under site exposure and varying weather conditions.
- Strong Tyvek backing: Reinforces mechanical strength and tear resistance during installation.
- High tack performance: Bonds quickly to Tyvek membranes, timber, and metal substrates.
- Durable acrylic adhesive: Ensures permanent adhesion with long-term ageing stability.
- Vapour control compatibility: Fully compatible with Tyvek breather membranes and vapour control layers.
- Easy application: Can be applied by hand or roller, conforming smoothly to irregular surfaces.
- Width specification: 75mm width provides secure lap coverage and robust sealing of wide joints.
Applications
- Membrane lap sealing: For joining Tyvek breather membranes and VCL overlaps.
- Penetration sealing: Ensures airtight joints around service penetrations and fixings.
- Window and door detailing: Maintains continuity of the air and moisture barrier at openings.
- Timber and steel framing: Provides weather-resistant sealing at junctions and interfaces.
Installation Guidance
- Surface preparation: Ensure substrates are dry, clean, and free from dust, oil, or frost before application.
- Application method: Apply firm pressure along the full tape length to achieve total adhesive contact.
- Temperature range: Apply between +5°C and +40°C for optimal adhesion; suitable for service from −40°C to +100°C.
- Overlap alignment: Centre the tape over the joint to ensure equal bond either side of the seam.
- Storage: Keep rolls flat and dry, stored between +10°C and +30°C, protected from direct sunlight.
Compliance & Performance
- Adhesive system: UV-resistant acrylic pressure-sensitive adhesive.
- Carrier backing: Tyvek HDPE film.
- Service temperature range: −40°C to +100°C.
- Water vapour resistance: Maintains airtightness and moisture barrier function within tested limits of Tyvek systems.
