Composite Decking Tape

What Is Composite Decking Tape?

Composite Decking Tape, otherwise known as joist flashing tape, is a weather-resistant adhesive material used to protect and enhance the performance of composite decking. This specialised tape creates a protective barrier against moisture, debris, and wear, ensuring that the substructure remains in excellent condition for years. 

In decking projects, its use is vital for preventing water infiltration at points where fasteners penetrate the surface. By forming a protective barrier, it minimises the risk of fasteners loosening over time, enhancing the deck's durability and structural integrity - especially in high-humidity environments or areas frequently exposed to rain.

Easy to apply and built to last, Composite Decking Tape complements the overall durability of composite decking systems.

How Does Composite Decking Tape Work?

Decking tape is designed to protect timber joists by creating a moisture barrier that prevents water from penetrating the wood, thereby reducing the risk of rot or decay. Applied to the top of the joists before deck boards are installed, it ensures that any water draining through the gaps between the boards does not come into direct contact with the timber substructure.

With a strong adhesive that forms a permanent bond to the wood, the tape provides a durable seal, safeguarding your deck's foundation for years to come.
