Taller Fence Panels
Taller fence panels between 4ft and 6ft, are much more useful for deterring unwanted visitors, the extra height makes them harder to get over and it offers increased privacy from prying eyes. It is worth making some distinction here between solid panels, like Featherboard (also known as Feather edge or Close board fencing) and Tongue and Groove effect, these provide much more security and privacy, because there are no spaces or gaps between the fence pales or boards. When compared to semi-solid panels like trellis, horizontal slatted panels Venetian or Woven panels. Privacy may be a concern though, as most of them are reasonably easy to see through, they do offer certain benefits though; more light can get through the open design, which is great if you want more light in your garden, they also can create wonderful light and shade effects.
Another bonus of fencing and trellis panels is that the gaps not only allow light through, but also air, or more importantly wind. In locations where strong winds are a problem a solid fence would present a barrier that won’t let any wind through it, this can weaken the fence over time and could result in the fence failing, breaking or being blown over, if the foundations are not strong enough. A panel that has some gaps or spaces offer less wind resistance and will allow wind to travel though it, this is just right for fencing windy locations.
Although a perfect compromise could be a combination of a low solid panels of say 3ft or 4ft high - which at this height, should not present too much of a barrier to the wind, with contemporary or trellis topper panels on the top, making the height up to 5ft or 6ft.
