Wraptite Detailing Tape 50m – All Sizes

A useful way of stopping unnecessary air leakage around openings and overlaps is to use Wraptite Tape, an airtight, tear-resistant tape with high vapour permeability for internal and external applications. It fully bonds to all standard substrates, suppressing air leakage around joints, openings, and penetrations. It is also suitable for permanent airtight sealing of membrane overlaps.

Composition:

Wraptite Tape consists of a triple-layer polypropylene micro-porous film laminate, with a proprietary acrylic moisture vapour permeable adhesive and silicone-coated PET release liner. Wraptite Tape is also available as a split-release liner for ease of installation.

Drying Capacity:

Wraptite Tape’s high vapour permeability allows damp sheathing to dry quickly and moisture vapour to escape. This ensures good indoor air quality and reduces the likelihood of mold, mildew, condensation, timber distortion, and metal corrosion.

Key Benefits:

• Airtight and vapour permeable
• Resilient composition, which resists punctures and tears during construction
• Flexibility, facilitating ease of application and detailing
• Wide operating temperature range (-40°C to +100°C)
• Can be left exposed for up to 90 days (North America) or 120 days (UK) during construction*
• No primer required
• Suitable for sealing insulation boards
• Free from Volatile Organic Compounds

Vapour Permeability
With an Sd rating of 0.039, Wraptite Tape provides a highly vapour-permeable, but fully airtight performance for multiple applications and conditions. These crucial characteristics allow moisture vapour to escape the structure easily whilst maintaining the integrity of the building envelope.

Installation Instructions
Wraptite Tape should be applied to all vertical and horizontal joints between insulation boards

• Ensure the surface of insulation boards is clean and free of dirt and grease before application
• Pull and fold back the release liner from the end of the tape, line up the tape over the joint, and apply pressure for the initial tack
• Ensuring the tape follows the line of the joint, continue to pull the release liner while taping over the joint
• Apply pressure to tape using a hand roller or successful adhesion
