Sealing Tape – Multifoil – Indoor & Outdoor Applications

Product Overview

This high-adhesion sealing tape features a 100mm width and 25m length, ideal for creating continuous airtight and windtight joints in hybrid insulation systems. The reinforced adhesive layer ensures durable bonding across membranes, boards, and junctions, maintaining consistent building envelope performance.

It forms secure seals over overlaps, penetrations, and perimeter interfaces, offering long-term protection against uncontrolled air movement and moisture ingress. The tape's flexible structure adapts to irregular surfaces and complex detailing, ensuring accurate installation along edges, corners, and service routes.

Suitable for both refurbishment and new build applications, this tape integrates effectively with reflective membranes, vapor control layers, and insulation panels to achieve reliable airtightness levels. Its robust construction supports consistent adhesion, contributing to stable thermal and moisture behavior in roof and wall assemblies.

Features & Benefits

• High-adhesion bond: Provides strong, durable sealing of membrane joints for long-term airtightness and moisture protection.
• Flexible application: Easily conforms to corners, edges, and uneven surfaces for continuous and accurate detailing.
• Airtight continuity: Maintains uninterrupted airtight layers in hybrid insulation systems for predictable thermal performance.
• Moisture resistance: Acts as a reliable barrier against moisture ingress at overlaps and junctions.
• Durable construction: Offers stable adhesion over time to ensure consistent building envelope performance.
• Versatile compatibility: Compatible with membranes, vapor control layers, insulation panels, and common substrates.

Applications

• Membrane joints: Seals overlaps on reflective and breathable membranes to maintain airtight and windtight performance.
• Perimeter sealing: Creates continuous boundary seals around openings, edges, and junctions.
• Insulation interfaces: Enhances airtightness at connections between panels, membranes, and structural elements.

Installation Guidance

• Surface preparation: Ensure surfaces are clean, dry, and free from dust before applying the tape.
• Tape placement: Position the tape centrally over joints or penetrations for full coverage.
• Pressure application: Press firmly along the tape's length to activate the adhesive and ensure continuous bonding.
• Temperature consideration: Apply within recommended temperature ranges for optimal performance.
