Enhanced Grain Decking

Use Millboard decking for all standard outdoor flooring applications (e.g. in residential, commercial, education, healthcare, leisure and hospitality) including:

• Ground-level terraces/ patios;
• Roof-level terraces;
• Balconies (subject to Building Control);
• Podium decks;
• Public spaces/ areas;
• Boardwalks;
• Pool surrounds;
• Jetties/ pontoons/ marinas

Millboard can be used as the decorative face for most outdoor designs, as long as it is fixed to a structural element.

Installation:

Millboard decking boards should be installed with a 4 mm gap between the boards and a 1 mm gap at the butt ends, to facilitate drainage. There is no need for a ventilation gap to be left under the Millboard decking boards. The maximum unsupported overhang for the boards is 50 mm, each cut board must be supported by a minimum of three joists. Each board must be screwed down with 2 x Millboard Durafix® stainless steel screw fixings where a board crosses a joist, and 3 x Millboard Durafix® stainless steel screw fixings at the ends of the boards. All installation recommendations set out in the installation guide found on the manufacturer's website.
