The 6FT x 6FT Ultra Heavy Duty Closeboard Fence Panel - Pressure Treated Brown is the extra-support version of our 6ft closeboard panel, manufactured in-house by East Coast Fencing for full-height rear and side garden boundaries where privacy and a solid visual screen are the main priorities. It measures 1830mm wide by 1800mm high with a listed depth of 45mm. The overlapping feather edge construction provides the traditional closeboard appearance, but the Ultra specification is aimed at customers who want more rail support through the height of the panel.
At the full 1800mm height, the five-rail layout is the clearest expression of the Ultra specification. The panel has the largest face area in the range, so shortening the distance between support rails gives the feather edge boards more frequent fixing points from top to bottom. For a sheltered garden the four-rail standard panel may still be appropriate; for an exposed run or a customer specifically prioritising panel stiffness, this is the direct upgrade.
This Ultra Heavy Duty panel uses 5 75 x 32mm backing rails, compared with 4 rails on our standard 6ft closeboard panel. The feather edge boards are fixed across those rails, so the additional support point reduce the unsupported span between fixings and make the panel stiffer as a complete unit. That is the practical reason to choose Ultra: not a different decorative style, but a more heavily supported version of the same closeboard principle. The panel remains unframed and is finished with weather capping along the top edge.
The timber is pressure treated and supplied in brown. For customers comparing the two treatment colours, the brown finish gives the darker initial appearance while the construction specification is what determines the standard-versus-Ultra difference. Use the closeboard fence panels category to compare the standard and Ultra versions at the same height rather than assuming that every closeboard panel has the same number of rails.
Full-height panels place more demand on the supporting fence structure than low panels. Set suitable posts accurately, keep each bay consistent and plan for a gravel board or other separation from damp ground. On exposed sites, the Ultra Heavy Duty construction is the comparison to make. On an Ultra panel, the extra rails do not remove the need for a properly built supporting fence. Pair the panel with suitable fence posts, keep posts plumb, and check the actual bay before fitting. On longer or more exposed runs, consistent post spacing and a straight base line are just as important as the panel specification itself.
Keep the bottom of the timber panel away from persistent ground moisture. A gravel board can take the low-level contact and splashback that would otherwise reach the feather edge boards, while also giving the panels a consistent line to sit above. If the panel needs to be reduced in width for a non-standard opening, cut carefully and re-treat fresh timber surfaces after trimming. Choose this Ultra version when the additional rail support is a meaningful benefit for the boundary, rather than simply because it carries a heavier-duty name.
