Timber hoardings are either constructed off site in panels and fixed in place on site, or built from scratch on site. Timber hoardings can take a long time to put together on site, unless prefabricated first. Usually they require modification on site by carpenters during installation to suit the landscape. Once the hoardings are built, cover strips and skirtings are added before the final painting and signage is completed. The main issues with using timber panel hoardings are that they take a relatively long time to install, they need to be erected by carpenters, they require adaption and painting on site, the paint finish deteriorates over a fairly short time and they produce a lot of waste once removed from site.
