Simply apply to the top of your joists to protect your decking subframe from rotting.

Our self-sealing, adhesive tape is Non-Butyl, meaning it is completely water-proof, weather proof and UV stable so it will keep its integrity for longer.

Choosing a Non-Butyl tape is particularly important when used on decking subframe joists. Other tapes such as Butyl and Asphalt Tapes can peel, shrink and /or split in certain weather conditions and have also been known to seep up into composite decking creating stains.

This tape is a must to protect and prolong the life of your decking subframe from rotting.
