Flashing Tape – Heavy Duty – Roofing Applications

Product Overview

Our Heavy Duty Flashing Tape, with a width of 150mm and a length of 10m, is a self-adhesive bituminous tape designed for creating a durable, watertight seal on a wide range of building substrates. It features a resin-modified bitumen adhesive combined with a protective foil facing, forming a robust barrier that resists tearing, weathering, and thermal cycling.

The pressure-sensitive adhesive securely bonds to brick, masonry, concrete roof tiles, timber, metal, and rigid plastics, ensuring flexibility at low temperatures and resistance to flow at high temperatures for reliable long-term performance. The adhesive mass strengthens over time, providing stability in both exposed and sheltered locations without needing separate adhesives or specialist tools. The foil surface offers a clean, uniform finish when in place, making it suitable for both remedial and new-build work where a broader coverage is required.

Features & Benefits

• Self-adhesive construction: Enables rapid installation without separate adhesives.
• Watertight sealing layer: Prevents water ingress across joints, laps, and interfaces.
• Robust foil facing: Provides tear resistance and stability under stress.
• Good substrate compatibility: Bonds to masonry, concrete tiles, timber, metal, and rigid plastics.
• Temperature-tolerant adhesive: Remains flexible in cold and resists flow in heat.
• Width specification: 150mm width for increased coverage on larger joints.

Applications

• Roof flashing repairs: Ensures watertightness around chimneys, parapets, and penetrations.
• Joint and lap sealing: Provides a continuous seal over roofing felt joints and repairs.
• Emergency waterproofing: Rapid solution for leaks during adverse weather.
• Decorative over-bridging: Accepts over-painting, subject to compatibility testing.

Installation Guidance

• Surface preparation: Ensure substrates are clean, dry, and free from contaminants; fill hollows over 3mm before application.
• Primer use: Apply primer on porous or rough substrates for improved adhesion.

• Material: Resin-modified bitumen with foil facing.
• Adhesive type: Pressure-sensitive.
