Most people examining trellis panels in a garden cannot instantly tell how they are constructed. At first glance, each panel appears quite similar to another. However, the difference between a jointed trellis panel and an overlap panel is one of the most important distinctions in garden joinery, and once you grasp it, you will never view trellis the same way again.
How overlap trellis is made
Most garden trellises sold in the UK are made using the overlap method. Battens are laid across each other at every intersection and secured, usually with staples or nails. This creates a panel where the intersections sit proud on one side and recessed on the other. It is a quick and inexpensive way to produce a trellis panel, and for many basic uses, it works sufficiently.
However, overlap construction has inherent limitations. The intersections are mechanical fixing points that experience constant stress as the timber expands and contracts with temperature and moisture changes. Over time, these points can become loose. Panels develop a shaky, rattling quality that no amount of maintenance can fully eliminate. The face of the panel is also naturally uneven, with the raised intersections catching light and shadow in a way that, to a discerning eye, appears visually busy and unrefined.
What jointed construction means
A jointed trellis panel is constructed quite differently. At each intersection, the battens are cut and assembled so that the crossing points sit flush on both panel faces. There are no fixings under stress, and no proud intersections. The panel is a single integrated structure rather than a series of crossing pieces held together at individual points.
The difference in appearance is immediately clear. A jointed panel has a clean, precise face that appears as a single surface rather than a collection of parts. Light falls evenly across it. The geometry is sharp. It simply looks more refined. Run your hand over the face of a jointed panel and it feels smooth and uniform from edge to edge. On an overlap panel, you will clearly feel the raised intersections. That difference is in the construction you can feel.
Why it matters for durability
The structural case for jointed construction is just as persuasive as the aesthetic one. Since the panel is integrated at every intersection rather than being reliant on mechanical fixing at crossing points, there are no weak joints prone to failure. The structure distributes load across the entire panel rather than concentrating stress at specific fixing points.
In practice, this means a jointed garden trellis panel maintains its shape and structural integrity significantly longer than an overlap equivalent. It does not rattle. It does not develop a loose, flexible quality over time. It is, from the outset, a fundamentally more solid and reliable piece of garden joinery.
The cost of doing it properly
A jointed trellis takes longer to produce. Each intersection must be individually cut and fitted, which is a skilled and time-consuming task. That’s why the overlap method dominates the market: it is faster, cheaper, and more suitable for volume production. The jointed method, however, is preferable for craftsmen producing one panel at a time to a standard, rather than in bulk.
At Stuart Garden Architecture, all our garden trellis panels feature jointed construction. It is one of the key aspects of our work and one of the most common remarks from clients when they see a panel for the first time. The flush face finish, the precision of the geometry, and the overall quality of the structure are direct results of this approach, and they set our trellis apart from nearly everything else available in the UK market.
Where it matters most
The difference between jointed and overlap trellis matters most where the panels are prominent in the design. Against rendered walls, framing a garden room, forming a significant section of screening, or incorporated into an arbour or pergola, the quality of the construction is always visible. In those situations, the clean precision of a jointed panel is not simply a technical detail; it is part of the garden’s architecture.
For clients investing seriously in their outdoor space, understanding the construction of trellis is important before choosing. The best timber garden trellis is not decided just by its pattern or finish, but by the quality of the joinery that holds it together.
