Flashing Tape – Heavy Duty – Roofing Sealing

Product Overview

This heavy-duty, self-adhesive flashing tape is designed to deliver a durable, watertight seal across a broad range of building substrates. With a width of 225mm and a length of 10m, it provides extensive coverage for various applications.

The tape combines a resin-modified bitumen adhesive with a protective foil facing, creating a robust barrier that resists tearing, weathering, and thermal cycling. Its pressure-sensitive adhesive bonds securely to materials such as brick, masonry, concrete roof tiles, timber, metal, and rigid plastics. It remains flexible at low temperatures and resists flow at high temperatures for reliable long-term performance.

Features & Benefits

• Self-adhesive construction: Provides a strong, immediate bond without the need for separate adhesives, enabling rapid installation.
• Watertight sealing layer: Creates a durable weatherproof barrier that prevents water ingress across joints, laps, and interfaces.
• Robust foil facing: Offers tear resistance and stabilizes the tape under thermal and mechanical stress for dependable service life.
• Good substrate compatibility: Bonds effectively to common building materials including masonry, concrete tiles, timber, metal, and rigid plastics.
• Temperature-tolerant adhesive: Remains flexible at low temperatures and resists flow at elevated temperatures for reliable year-round performance.
• Width specification: 225mm supports large roof transitions, extensive patch repairs, and wide-span detailing where broad coverage is beneficial.

Applications

• Roof flashing repairs: Restores watertightness around chimneys, parapets, and roof penetrations.
• Joint and lap sealing: Provides a continuous seal over roofing felt joints, slate repairs, and small gutter interfaces.
• Emergency waterproofing: Acts as a rapid, self-bonding solution for leaks during adverse weather.
• Decorative over-bridging: Accepts over-painting where required, subject to compatibility testing.

Installation Guidance

• Surface preparation: Ensure all substrates are clean, dry, and free from contaminants, with hollows over 3mm filled before application.
• Primer use: Apply a suitable primer on porous or rough substrates to improve adhesion, allowing it to dry fully before use.

Material: Resin-modified bitumen with protective foil facing.
