Duflex is a high quality composite panel made to order under controlled conditions. The skin laminates can be timber, glass, carbon or kevlar in epoxy and the core materials can be virtually any commonly employed material including PVC foam, end grain balsa or aramid honeycomb.
Note that we do not specify balsa core for the construction of our boats. PVC cores are specified for the main structure. Paper honey comb core may be used for furniture panels to minimise weight in the saloon furniture but PVC core is the standard specification.
The panel shapes are defined by routing 2.4m x 1.2 m panels which are joined on the build site to create the full size and shape of the required panel. They have a unique scarf join in the long edge which eliminates the need for glass tapes on that edge, substantially reducing the taping and fairing work.
Duflex panels have a strength to weight ratio that is difficult to match with conventional laminating techniques. The panels have a peel ply finish which requires very little preparation as a finished surface.
The primary features of ATL’s DuFLEX kits are;
•High quality composite panels manufactured under controlled conditions to achieve a consistent laminate with a high fibre ratio.
•The proprietary Z join that makes joining the panels a breeze and avoids the need to tape the panels on the long edge.
•A streamlined process managed by ATL Composites that integrates design, engineering, panel nesting, laminating, and delivery to your workshop door, combined with technical support and service that is unsurpassed in the industry.

We have a highly productive working relationship with ATL Composites that goes back to 1986 when the then manager of Adhesive Technologies in Sydney, Graeme Bird, built the 8m trimaran ATL to test and promote Durakore and the West Resin System.
ATL (the trimaran, not the company) has had a number of different owners and different names over the years and has an impressive racing history including winning the Queensland Multihull Championships in 2010. She is still actively being campaigned on the race circuit today (2018).
ATL have been developing and selling the DuFLEX kits since 1994. The kits are used enthusiastically by amateur builders, professional yards and even production builders of motor yachts and
sailing yachts, multihull and mono.
