Description

Extend the life of your decking frame with NeoTimber® Decking Joist Tape. Designed to protect timber substructures, this tape provides a strong seal against water and weather damage. Apply it as a cap along joists, noggins, or double joists to prevent water rot and decay.

Decking Joist Tape creates a waterproof barrier that keeps moisture out and timber dry. It works by sealing the top of wooden joists, helping to stop frame weathering before it starts. Use it with NeoTimber® composite decking boards for maximum protection and performance.

Made from durable non-butyl, self-sealing material, this Decking Joist Tape delivers a high-strength polymer acrylic adhesive. This ensures a firm bond and long-lasting moisture resistance, even in harsh conditions. Its weatherproof design adds extra peace of mind during wet and cold months.

Choose from three sizes: 50mm for joists, 82mm for noggins, and 100mm for double joists. Each roll offers 20 metres of reliable coverage in a sleek black finish. Quick and easy to install, it helps protect your deck with minimal effort.

What is NeoTimber® Decking Joist Tape used for?

NeoTimber® Decking Joist Tape is designed to protect timber subframes from water damage and rot. It seals the tops of joists, noggins, and double joists to prevent moisture from penetrating the timber, extending the lifespan of your decking frame.

The tape creates a waterproof barrier over timber joists, helping to keep them dry and shielded from rain, frost, and general weathering. This reduces the risk of rot and decay, ensuring your deck remains strong and stable over time.

The tape is available in three sizes to suit different parts of your subframe: 50mm for standard joists, 82mm for noggins, and 100mm for double joists. Each roll provides 20 metres of coverage.

Is the Joist Tape easy to install?

Yes. The self-sealing, non-butyl design with high-strength polymer acrylic adhesive makes installation simple and mess-free. Just apply it along the top of your joists to create an instant weatherproof seal.

Can I use Decking Joist Tape with NeoTimber® composite decking?

Absolutely. The tape is recommended for use with NeoTimber® composite decking boards, particularly on timber subframes, helping to ensure maximum protection and long-term outdoor performance.
