Self Adhesive Flashing Tape - 100mm 150mm 225mm

Self Adhesive Flashing Tape | 100mm, 150mm, 225mm Widths

Our self-adhesive flashing tape is an essential waterproofing solution specifically designed for polycarbonate roofing installations. This premium-quality tape creates a reliable, long-lasting seal between your polycarbonate roof panels and adjacent walls, glazing bars, or ridge sections, ensuring complete protection against water ingress and weather damage. Available in three convenient widths to suit different applications and roof configurations, this versatile flashing tape is a must-have for any polycarbonate roofing project.

Manufactured from durable, weather-resistant materials with a powerful adhesive backing, this flashing tape bonds securely to polycarbonate, metal, wood, brick, and most common building materials. The flexible nature of the tape allows it to conform perfectly to contours and corners, creating an airtight, watertight seal that prevents leaks, drafts, and moisture penetration. Unlike traditional lead flashing or mortared solutions, this modern alternative requires no specialist skills or tools, making it ideal for both professional installers and DIY enthusiasts looking for a quick, clean, and effective sealing method.

The 100mm width is perfect for standard glazing bar cover strips and narrow junction points where space is limited. The 150mm width offers versatile mid-range coverage, ideal for most wall abutments and general flashing applications on typical conservatory or lean-to installations. The 225mm width provides maximum coverage for wider wall plates, exposed sections, or situations requiring extra protection against driving rain and severe weather conditions. All widths feature the same high-performance adhesive and weather-resistant construction, ensuring consistent reliability regardless of which size you choose.

Installation is remarkably straightforward and requires no heat, flame, or special equipment. Simply ensure the surface is clean, dry, and free from dust or debris, then peel away the protective backing and press the tape firmly into position, smoothing out any air bubbles as you go. The aggressive adhesive creates an instant bond that only strengthens over time, while the flexible material accommodates thermal expansion and contraction without cracking or peeling. This flashing tape maintains its integrity through temperature extremes, UV exposure, and years of weathering, providing maintenance-free protection that won't degrade, corrode, or require replacement.

Suitable for new installations and repairs alike, this self-adhesive flashing tape is the professional's choice for sealing polycarbonate conservatories, carports, canopies, lean-tos, pergola roofs, and garden room glazing. It creates a neat, discreet finish that's far superior to messy sealants or unsightly metal cappings, while delivering superior waterproofing performance that protects your investment and keeps your space completely dry. Whether you're building from scratch or fixing an existing leak, this flashing tape offers the perfect combination of performance, ease of use, and value for money.
