Deckchair Systems Ltd have developed three low cost timber options to provide support for decking joists, to overlay membrane or concrete deck sub structures. The Deckchair has a registered design mark and the rubber foot is SGS tested to carry weights of over 20 tons. The system is plastic free, made from recycled tyres and LVL timber using 100% of the tree, making it a Green option. The Deckchair systems were developed in New Zealand at the request of designers and builders to provide a low-cost, easy to use support for decking joists. The three options are mounted on the Deckchair Rubber Foot Joist mount.

The traditional option is to pre-cut a joist to the specified angle (1.5 to 2 deg). The Deckchair rubber foot is mounted under the joist (max) 450mm apart to provide the 15mm clearance required. Made from a composite rubber derived from recycled car tires, the Deck Chair Joist Mount is manufactured by one of the world’s leading rubber recycling companies, with decades of industry experience in producing a range of composite rubber surfaces that are hardwearing and long lasting – from playgrounds to sports tracks and hundreds of other uses.

Builders assemble a frame from treated timber using the specified sized joists and boundary joists to the size of the deck. This frame then needs to be leveled to the required height by fixing the frame to the Premade 2 deg Deckchair LVL Deck Jack Legs that come complete with Deckchair Rubber Mount. These are fixed every 450c (max) Once the deck frame is fixed level any surplus jack leg is cut off level using a sabre saw or similar.

The Deck Chair Adjustable Joist is made from H 3.2 grade laminated veneer lumber (LVL), and produced by a leading NZ supplier. It will withstand warping and twisting over time and is certified to deliver decades of substructure support. The Deck Chair Adjustable joist comes pre-fitted with Deck Chair Joist Mounts for quick and simple installation.
