What is the purpose of joist tape on a deck?
The core purpose of applying support joist tape on the deck is to protect the wooden structure below the deck and significantly extend its service life through waterproofing.
◉ Core function: Waterproof and moisture-proof
This is the primary and fundamental purpose. The structural framework of the deck, such as joists and crossbeams, is usually made of wood. The joist tape forms a waterproof barrier at the top of the joists to prevent moisture from directly contacting and penetrating into the wood.
◉ Other functions:
• Protecting metal fasteners: Tape can isolate metal from wood that has undergone anti-corrosion treatment, preventing chemical reactions and corrosion caused by contact between the two. At the same time, it can also wrap around the nail holes of fasteners such as screws and nails, block moisture, and prevent rusting and failure.
• Enhance structural strength: Tape can make screws and fasteners more tightly and firmly connected to wood.
• Reduce squeaking noise: Deck boards may experience friction with the support beams when they expand or contract due to heat, or when people walk. The support beam tape can provide a buffer layer, effectively eliminating or reducing this friction noise.
• Extend service life: By isolating moisture and reducing wear, it helps maintain the structural integrity of the support beam and avoid premature damage.
