A column reads as finished or unfinished at the top, not the middle — an unadorned capital undersells even a well-proportioned shaft below it. Unitex Column Capping gives builders and renderers a lightweight, precisely formed capital that sits cleanly on top of a column, matches the diameter of the shaft it’s crowning, and finishes as part of the same render system as the rest of the facade, without the weight or on-site carving a masonry or cast capital demands.

What’s in the Column Capping Range

The range covers three round capital profiles, numbered Capital #1, #2 and #4, each carrying a distinct decorative line so the finished look can be matched to the style of column and the wider facade. Capital #4 is the standout of the three — a bellied, flared design that gives a noticeably more ornate, classical capital than the straighter #1 and #2 profiles. Each profile is available in a set of standard diameters (210mm, 260mm, 290mm and 350mm) to suit the corresponding Uni-Shape column shaft, and square bespoke equivalents are available across the same profile and diameter range for facades built on a squared, more contemporary column line. A separate stock ring-profile capital is also available in two diameters, offering a slimmer, simpler capping option where a full decorative capital isn’t the brief.

Matching Capping to Your Columns

Column Capping is designed to pair directly with the Uni-Shape column shafts range, which is supplied in 260mm and 350mm standard diameters (custom diameters and heights available on request). Because both ranges are sized against the same diameter references, a builder or designer can select a column shaft and its capital together with confidence the two will meet cleanly on site, rather than relying on-site trimming to make an ill-fitting capital work.

Built to Finish, Not Just to Fit

Like the rest of the Uni-Shape range, Column Capping is mechanically fixed rather than glued in place. Unitex takes this position deliberately: an adhesive-only bond relies on surface contact and can weaken over time as it’s exposed to weather, while a properly selected and applied mechanical fixing is built to last the life of the installation. Capitals are also never texture-coated, so the crisp, defined lines of the profile stay sharp — the recommended finish is a smooth Uni-Flex Membrane or Unitex PTC coating in the chosen colour, keeping the capital as sharp as the day it was installed.

Frequently Asked Questions

Can Column Capping be matched to any column diameter? The standard Capital #1, #2 and #4 profiles are supplied in 210mm, 260mm, 290mm and 350mm diameters to suit the standard Uni-Shape Columns range. Square bespoke capitals are available at the same diameters, and custom sizing can be discussed with the technical sales team for non-standard column shafts.

How is Column Capping fixed to a column? Column Capping is mechanically fixed, consistent with the rest of the Uni-Shape range, rather than relied on to hold in place with adhesive alone. This is a deliberate durability decision, not an installation shortcut.

Can a damaged capital be repaired without full replacement? Hairline cracks in Uni-Shape mouldings can typically be repaired in place rather than requiring full replacement — speak to your technical sales representative about the process for your specific capital profile.
