Replacing traditional wooden joists while creating a 100% dry space in the area below. It’s a single system, integrative design that eliminates add-on gutter systems, waterproofing membranes or drainage substructures.

Three products in One!

Waterproof Substructure – Deck drain allows for 100% waterproof area underneath

Joist System for Decking – Low profile structural system will span up to 1.8metres long

Finished Ceiling Underneath – Powdercoated beadboard finished soffit ceiling

Components

With only two components, NexGEN DryJoist is perfect for new construction or remodelling existing structures and provides a lifetime of strength and durability. DryJoist is capable of spanning 1800mm without the need of support beams and provides structural support for deck boards every 150mm on centre. Installation requires standard deck tools and the lightweight aluminium boards are much easier to handle than traditional materials such as pressure treated timber.

Important

Made of marine-grade, precision-extruded aluminium, the system is strong enough to replace the need for conventional wood joists and is impervious to rot, insects, mildew, and fire.
