Upgrade Your Timber Subframe With NeoTimber®'s Long-Life, High-Performance Decking Joist Tape
Why do you need to use decking joist tape? Let us tell you... Laying composite decking onto a poorly prepared timber subframe is a little like building a house on sand. While we generally believe that opting for composite joists or recycled plastic subframe solutions is the best way forward for decking installations, we do still see the merits of using timber as a subframe for composite decking installs.
After all, it is a very diverse, low-cost and accessible material that is used in a number of outdoor applications and remains the most popular solution for our customers.
NeoTimber® decking joist tape is designed to enhance timber's longevity and overall performance, better preparing your subframe for what the elements have to throw at it.
Why Opt For NeoTimber® Decking Joist Tape?
Joist tape provides users with more peace of mind, as it is designed to enhance the longevity and performance of timber subframes. Manufactured in the UK, the product is designed to protect timber deck substructures by providing a completely waterproof seal on the surface of the timber joist. Without this, exposure to the elements can result in significant deck frame weathering and eventually lead to a rotting timber joist.
The most common area for this damage to occur is where the deck boards come into contact with the deck substructure. With a permanent adhesive bond for 50 years and a 25-year guarantee, this significantly adds to the life of your deck frame by sealing the joist where it is most vulnerable. What's more, the decking joist tape has been tested with all timber treatments, so you can rest assured that application will be simple and hassle-free.

NeoTimber® decking joist tape is a non-butyl tape. Non-butyl tapes are particularly suitable for this application, as they are completely UV stable and keep their integrity for longer. This means they offer several advantages over both butyl and asphalt tapes. In addition to this, the tape is stable from -40°C to +93°C, with no cracking, peeling or strength loss.
Our Decking Joist Tape Sizes
NeoTimber® decking joist tape comes in three sizes, all of which are supplied in 20 linear metre rolls and designed to cover a wide range of subframe applications and settings. We break down each application below:

NeoTimber® 50mm Joist Tape

Our most popular solution, this width is designed to fit directly onto the top of a 50mm wide joist, providing a protective layer between the underside of the deck board and the timber joist.
NeoTimber® 82mm Joist Tape

This width is for application on the bottom end of joists that come into direct contact with the ground. The wider adhesive strip wraps around the bottom of the joist and also protects the sides.
NeoTimber® 100mm Joist Tape

The widest joist tape we offer, ideal for areas of the subframe where joining double joists are situated. The 100mm extra-wide decking joist tape offers ultimate protection across a wider surface area.
