Tyvek Tape

The versatile Tyvek tape sealing solution secures housewrap and membranes for exceptional airtightness and waterproofing. It handles challenging conditions, including UV exposure, and effectively protects the wall from moisture and air infiltration.

What Is Tyvek DuPont Tape?

Tyvek DuPont tape is a specialist adhesive tape for seams and overlaps in Tyvek membranes and other weather barriers.

Using DuPont tape optimises the Tyvek wrap’s effectiveness. Once applied, the tape seals gaps to prevent air and moisture from passing through the building envelope.

It is available in different adhesive types designed for specific applications.

What Is Tyvek Adhesive Tape Used For?

DuPont adhesive tape is used on Tyvek housewrap and similar breathable membranes.

• It is applied to close seams, overlaps, and cut-outs.
• It seals spots around windows, doors, and corners where air or water might pass.

The tape bonds strongly to the membrane, maintaining the wall’s airtight and weather-tight performance.

Types Of Tyvek Tapes

These are the main Tyvek tapes available:

DuPont Tyvek Acrylic Tape

This comes with an acrylic adhesive and can be single-sided or double-sided (sticky on one or both sides).

The strong but flexible polyethylene backing resists moisture, dust, and dirt well.

It is great for sealing overlaps, repairs, or around smaller penetrations – like pipes or small cut-outs.

Sizes include:

• 75 mm × 25 m for single-sided
• 50 mm × 25 m for double-sided

Acrylic-based tape sticks well to a variety of materials but lacks the extreme sealing strength of butyl for high-moisture or highly exposed joints.

Use Tyvek Acrylic Tape when:

• Sealing Tyvek overlaps (for instance, where two sheets overlap)
• Making small repairs on the wrap or membrane
• Sealing pipes, small penetrations, or less-critical seams

DuPont Tyvek Double-Sided Butyl Tape

This Tyvek double sided tape features a rubber adhesive.

The butyl rubber adhesive element gives it high resistance to water, air, and humidity, making it ideal for junctions between different substrates such as metal, timber, or masonry, or where there is a risk of water ingress.

Use it to:

• Get airtight and waterproof seals.
• Provide weather-resistant seals around door frames, windows, chimneys, and other exposed junctions.
• Bond Tyvek and similar membranes to different building materials like wood or metal.

What is Tyvek tape?

This is a special seal tape for Tyvek housewrap and other breathable building membranes. Its strong adhesion closes up overlaps, joints, and tiny openings where air and moisture could pass through.

How much Tyvek tape do I need?

One 25–30 m roll typically covers approximately 50–70 m² of membrane. Buy enough tape to cover all overlaps, joints, window and door edges, plus any cuts made in the membrane. To avoid running short, add an extra roll in projects with complex layouts, plenty of windows, or challenging corners.

Where to use Tyvek tape?

On Tyvek housewrap and other breathable barriers:

1. On joints, overlaps, and cut-outs.
2. All around doors, windows, corners, and service penetrations where air or moisture could pass through.
3. For small repairs.
4. To tidy up edges during installation.
