New Zealand is where U-DEK® began.

It was developed by foam manufacturer, Ultralon®, whose parent company is Skellerup, the same people who have brought you Red Bands for over 60 years. With a heritage like that, it isn’t surprising that U-DEK® has become popular with the discerning and established NZ marine community.

U-DEK® marine decking is available in kit form - from one of the Ultralon® facilities (Auckland or Christchurch), from an Authorised Installer, or from OEM boat manufacturers across the country.

Small packs of U-DEK® are available for DIY installation from several chandleries or from our online shop.
