Construction Tapes Explained

Choosing the Right Construction Tape for the Job

Construction tape might seem like a small part of a build, but the right tape plays an important role in creating a durable, weather-resistant and high-performing building envelope. From sealing wall wraps and membranes to joining insulation, flashing penetrations and creating airtight connections, construction tapes are designed for a wide range of applications. Here are the most common.

The Different Types of Construction Tapes

Building Wrap and Membrane Tapes

These hand-tearable tapes help maintain continuity and support an airtight, watertight building by sealing overlaps, joins and penetrations.

Use: These tapes are used for seaming and jointing breathable building wraps, reflective foil insulation, door openings and other penetrations.

Flashing Tapes

Flashing tapes provide additional protection around vulnerable areas where water could enter the building envelope.

Use: Windows, doors, openings, penetrations, junctions and transitions.

Insulation Tapes

Designed for sealing, joining, reinforcing or repairing insulation foil and insulation batts to ensure an airtight seal.

Use: Roof, wall, underfloor and ceiling insulation.

Joist Protection Tapes

These tapes protect timber joists, deck subframes and decking fixings from moisture. They’re designed for durability and weather resistance and can be hand-torn for easy installation.

Use: Timber or steel-framed decks.

General-Purpose Construction Tapes

General-purpose tapes can be useful for repairs and a range of construction tasks, but they shouldn’t automatically be substituted for products specifically designed for building-envelope applications.

Why Choosing the Right Construction Tape Matters

An unsuitable construction tape can lose adhesion, lift or peel over time, leaving gaps around joins and penetrations. This can compromise weather protection, airtightness and the overall performance of insulation, membranes and flashings, issues that are often difficult and costly to fix once a build is complete. Selecting a tape that’s purpose-built for its application, and installing it correctly, is one of the simplest ways to protect the long-term performance of a building envelope.
