50mm Thermofloc Adhesive Tape - Airtight Sealing for Vapour Control Layers & Membranes - 25m roll

50mm Thermofloc Adhesive Tape is a high‑performance polyethylene sealing tape designed for creating airtight, durable joints. It ensures a continuous, airtight building envelope that prevents uncontrolled air leakage and protects the insulation from moisture ingress. The tape is suitable for sealing membrane overlaps, stapling lines, and penetrations, as well as for airtight masking of timber‑based boards such as OSB and plywood. The tape uses a solvent‑free acrylate adhesive, offering long‑term elasticity, strong adhesion, and resistance to ageing. When used as part of the Thermofloc system, it contributes to a continuous, efficient and certified airtight layer, essential for achieving high thermal performance and preventing condensation risks.

CHARACTERISTICS

• Airtight sealing - ensures reliable bonding of vapour control layers and breather membranes.
• System‑matched performance - designed specifically for Thermofloc membranes for maximum compatibility.
• Solvent‑free acrylate adhesive - long‑lasting, elastic and resistant to ageing.
• Suitable for timber boards - adheres to OSB, plywood and other timber‑based substrates.
• Essential for airtight construction - prevents thermal bridging and moisture ingress.

APPLICATIONS

• Sealing vapour control layers
• Sealing breather membranes
• Masking joints in OSB/plywood
• Airtight detailing around penetrations
