You have a number of options when searching for the perfect cladding profile for your shed. One of these options is feather edge cladding. However, it is often considered a low quality option for shed cladding and this reputation is entirely undeserved. This type of cladding profile is affordable and makes use of thin narrow panels.
One of the most common misconceptions associated with this type of cladding profile is that the small section size and thin panels might lead to distortion and warping in the future. Feather boards are available in many different widths ranging from the typical 100 mm to more than 200 mm. The bigger feather edge boards have the advantage of being thicker which keeps the timber in place and reduces the risk of distortion and warping.
To make the installation weather tight, experts recommend overlapping individual boards similar to fish scales. One of the most common mistakes installers make when installing this cladding profile is that they keep the overlap smaller than the recommended size. Experts recommend a minimum overlap of 40 mm for board width of 150 mm and an overlap of at least 50 mm for board width of 200 mm. This much overlap is necessary to allow for any kind of expansion and contraction in the boards. This also provides ample protection from wind driven rain.
As far as the style of feather edge cladding is concerned, it has a much more rustic appearance and the boards are often supplied with a rough sawn finish. It is also an advantage as the boards are cheaper and no thickness is lost due to the planning process. The boards are typically cut from wet timber which means the boards tend to shrink with time. Experts recommend taking into account shrinkage of as much as 15 mm in 2 to 3 years and make sure the overlap isn’t less than the recommended size.
As far as installation is concerned, it is recommended to fix a nail at least 10 mm above the upper edge of the last board. While you might get advice to use two nails per board but experts recommend using only one nail as two nails might not allow the board to shrink properly which can cause splitting. Also, the end joints need to be staggered to ensure that no two boards are joined at the same place.
Overall, feather edge cladding offers a number of advantages as it is affordable and offers a rustic appearance but the installation needs to be perfect in order to make it as weather tight as possible.
