Joist Tape Protecting your deck’s structural integrity

What Is Joist Tape: A Brief Introduction

Experience the Pacific Northwest with Confidence: The Benefits of Composite Decking and the Importance of Joist Tape

In the Pacific Northwest, where the weather and climate can be demanding, choosing the right decking material is crucial. Composite decking offers unparalleled benefits that allow you to create an outdoor space that stands the test of time, even in locations like Washington State, where the desire for durable outdoor gathering spaces is constantly growing.

Composite and PVC decking products have a remarkable lifespan of 25+ years, making them an excellent investment. However, it’s important to protect the underlying timber framing to ensure maximum longevity. That’s why we highly recommend the use of protective joist tape on every deck project. By applying a thin, waterproof membrane to your deck’s joists, double joists, rim joists, bearers, ledger boards, and stringers, you can enjoy a range of benefits:

Reducing future maintenance: Joist tape acts as a barrier, shielding your deck’s structural components from moisture, which can lead to rot and decay. By preventing water penetration, you minimize the need for frequent repairs and maintenance, saving you time and effort in the long run.

Preserving structural integrity: The strength and reliability of composite decking rely on the quality of the underlying structure. Joist tape adds an extra layer of protection, preventing moisture-related issues that can compromise the stability and lifespan of your deck. With a well-protected substructure, you can ensure your composite decking remains strong and secure for years to come.

Enhancing fastener grip: Joist tape helps hold deck screws and fasteners tighter and stronger, further reinforcing the overall structural integrity of your deck. This added stability ensures that your deck remains safe and secure, even in the face of harsh weather conditions.

While the global market for composite decking continues to grow, with an estimated size of US$5.8 Billion by 2027, the need for maintenance remains minimal due to the longevity and durability of composite materials. However, it’s important to recognize that most substructures, such as bearers and joists, are typically made of timber. Without proper protection, these components can start to rot in as little as 8 to 10 years, despite being treated timber.

When selecting joist tape, consider these critical factors:

Type of material: Joist tape is available in acrylic, asphalt, and butyl options. Opting for a butyl-based tape ensures superior protection and durability. Butyl adhesives offer greater stickiness and can withstand a broader range of temperatures, making them ideal for challenging climates.

Ease of installation: Modern joist tapes are self-adhesive, making them easy to install. You can seamlessly apply them to the tops of the substructure before adding deck boards, ensuring comprehensive protection from the start.

Cost-effectiveness: Butyl tape provides excellent peace of mind at a minimal cost. By incorporating deck flashing tape into your construction plan during the installation of a new deck or as part of a deck replacement project, you ensure long-term protection and extend the life of your investment.
