which is better
featherboard or lap panels?
Though this style is attractive, the timber pales that are used are usually only dip treated and approximately between only 5-6mm thick which makes the timber highly susceptible to wet and dry rot as well as insect attack.
While larch lap fencing panels are considered a good option for enhancing privacy in the garden they are often manufactured in high quantities using cheaply sourced timber which rarely undergo any considerable pressure preservation treatment. Dip or brush treatment will only treat the surface which does not penetrate through the outer sapwood to the heartwood.
Over time the individual pales will begin to fade and distort leaving unsightly gaps in the panels, compromising the privacy and structural integrity. These cheaply made lap panels are often constructed using plated steel nails or staples that will rust in a short time, causing rust to run down the fencing.
Another disadvantage of lap panels, if climbing plants are placed near these panels then the plants will sometimes grow through the panels which can cause the slats to move and for the gaps to appear.
