Air Sealing Tape

Tape Description:

This scrim-reinforced PE single-sided Air Sealing Tape bonds directly to OSB, plywood, membranes, and other common building substrates—often without the need for primer. Its elastic backing stretches without tearing, allowing it to conform tightly around pipes, cables, corners, and irregular penetrations.

Engineered for long-term stability, this airtight sealing tape maintains strong adhesion in both high and low temperature environments and withstands UV exposure for up to 3 months. Its water-impermeable and driving-rain-proof structure offers reliable protection in roof and façade applications.

As a versatile airtight tape, it is ideal for sealing non-breathable membranes, vapor barriers, airtight membrane systems, and structural joints around doors, windows, electrical penetrations, and service lines.

Features & Benefits:

• Superior Airtight Seal: Extremely strong adhesion at high and low temperatures. Creates a permanent airtight and windproof bond. Bonds to OSB, wood, metals, membranes, plastics, and more.
• Durable & Weather-Resistant: UV resistance up to 3 months. Temperature-resistant from -40°C to +100°C. Prevents air, moisture, and vapor infiltration.
• Flexible, Elastic & Reliable: Scrim-reinforced backing stretches without tearing. Maintains seal during building movement. Clings securely around pipes, cables, and irregular shapes.
• Easy Installation: Fast application on interior surfaces. Primer usually not required.
• Vapor-Control Properties: sd value < 2 m (≈1.7 perms). Prevents condensation build-up behind airtight layers.
• Weather & Water Protection: Waterproof and driving-rain-proof. Provides long-term protection for roofs, facades, and cold rooms.

FAQ:

Q1. Is this Air Sealing Tape suitable for OSB panels?
A: Yes. It is specifically designed for direct adhesion to OSB surfaces without needing a primer in most cases.

Q2. Can it be used around windows and doors?
A; Absolutely - this airtight tape is ideal for sealing window frames, door openings, and penetration joints.

Q3. Does it work in cold temperatures?
A: The tape is designed to maintain adhesion down to -40°C once installed. Installation should occur between 0°C and 50°C.

Q4: Does this airtight sealing tape require a primer?
A: No. Due to the extremely strong adhesion of its acrylate dispersion base, this tape bonds reliably to many common building materials—including concrete, wood, metal, and plaster—without needing a primer in most applications.

Q5: What is the benefit of the scrim-reinforced backing?
A: The fiberglass scrim reinforcement provides elasticity and high tensile strength, meaning the airtight membrane tape will stretch to accommodate structural movement and cling tightly around irregular shapes without tearing.
