Air Sealing Tape

Tape Description:

Constructed from a robust polyethylene (PE) film and reinforced with a fiberglass mesh, this single-sided Air Sealing Tape bonds directly to common building substrates—including OSB, plywood, and membranes—most often without the need for an additional primer. The acrylic dispersion adhesive provides an extremely strong, instant tack that remains stable in both high and low-temperature environments.

The tape features a distinct mesh reinforcement within its elastic backing. This allows the tape to stretch without tearing, making it highly conformable when wrapping tightly around pipes, cables, corners, and irregular wall penetrations.

Built for long-term reliability, the tape is water-impermeable, driving-rain-proof, and can withstand direct UV exposure for up to 3 months. Whether sealing a cold room or finishing a modern façade, this versatile Airtight Tape ensures your vapor barriers and non-breathable membrane systems remain entirely uncompromised.

Features & Benefits:

• Superior Airtight Seal: Delivers exceptional adhesion at both high and low extremes (-40°C to +100°C), creating a permanent, windproof bond on wood, OSB, metals, membranes, and plastics.
• Highly Flexible & Elastic: The scrim-reinforced backing stretches without tearing, accommodating natural building movement while clinging securely to irregular shapes and penetrations.
• Primer-Free Application: The aggressive acrylic dispersion adhesive ensures fast, easy interior installation, acting as a highly effective osb tape without the need for liquid primers in most applications.
• Advanced Vapor-Control: Features an sd value of < 2 m (≈1.7 perms), preventing harmful condensation build-up directly behind airtight layers.
• Durable Weather Protection: Completely waterproof and driving-rain-proof, offering outstanding long-term protection for roof systems and facades, alongside UV resistance for up to 3 months.

FAQ:

Q1: Is this Air Sealing Tape suitable for OSB panels?
A: Yes. It functions as an ideal osb tape, specifically designed for direct, permanent adhesion to OSB surfaces without requiring a primer in the vast majority of cases.

Q2: Can it be used to seal around windows and doors?
A: Absolutely. This Airtight Tape is perfect for sealing window frames, rough door openings, and surrounding penetration joints to prevent drafts and moisture entry.

Q3: Does the tape maintain its seal in cold temperatures?
A: Yes. While installation should ideally occur between 0°C and 50°C, the tape is formulated to maintain its strong adhesion in operating temperatures down to -40°C once applied.

Q4: Does this airtight sealing tape require a primer?
A: No. Thanks to its highly aggressive acrylate dispersion adhesive, it bonds reliably to common building materials—including concrete, wood, metal, and plaster—without a primer for most standard applications.

Q5: What is the benefit of the scrim-reinforced backing?
A: The integrated fiberglass mesh (scrim) provides the tape with high tensile strength and elasticity. This ensures the airtight sealing tape can stretch to accommodate minor structural shifts and mold smoothly over irregular profiles without fracturing or tearing.
