U-DEK^® marine decking is owned, manufactured and distributed around the world by Ultralon^® International Foams.

Over the past forty years, Ultralon has established itself as a niche manufacturer of high quality closed-cell cross-linked foams, with a very tight consistent cell structure. As a result, Ultralon has focused on market sectors where foam performance is key and includes supply to the world’s top 12 ski and snow board boot manufacturers and to various companies making protective head gear for rugby union and rugby league head gear. The company also supplies PE and EVA foam to the orthotic, construction and packaging sectors around the world. U-DEK^® is the company’s marine brand which is focused on the production and supply of foam for marine decking in the USA, APAC and EU regions.

U-DEK^® marine decking is available in kit form from an Authorised Dealer or from OEM boat manufacturers across the country.

U-DEK^® marine decking is a great looking and high performing option for all types of marine craft, from sailing yachts, motor yachts, trailer boats, to RIBS and personal watercraft.

It is made from lightweight closed cell foam, offering a high level of comfort underfoot and excellent traction in all conditions. Durable, low maintenance, U-DEK^® has been designed specifically for deck kits and is supplied in various colours and tread options to suit individual styles.

As a leading global manufacturer of PE and EVA foam, Ultralon^® Foam International designs and produces U-DEK^® using our own dedicated plant and IP. Tightly controlled manufacturing processes, careful selection of raw materials, high level technical expertise and the latest technology and equipment, enable us to offer customers quality, reliability and consistency of product.

Our closed-cell chemically cross-linked foams are manufactured from polyethylene (PE), ethylene-vinyl acetate copolymers (EVA) or a high-tech blended copolymer. The fine cell structure gives minimal water absorption, a high buoyancy rating and excellent chemical resistance.

Ultralon^® foams are produced in moulded block form and can be trimmed to size and thickness. They are easily processed, using standard foam-processing machinery. No chlorofluorocarbon (CFC) product or derivatives are used, and no organic fillers are added to foams.
