What it's used for
- Closeboard panel fencing for garden boundaries and privacy screening
- Cladding for sheds, garden buildings, and outbuildings
- Horizontal lapped cladding on timber-framed structures
- Replacement boards on existing feather edge fences
Fitting and handling
Store boards flat and off the ground prior to installation, ideally under cover, to prevent warping before fixing. When building a closeboard fence, fix boards vertically to arris rails with a minimum 25mm overlap between each board, working from one end and checking for plumb as you go. These boards are supplied ready to paint or stain with an appropriate exterior preservative finish, or they can be left to weather to a natural silver-grey over time.
FAQ
What overlap should I use when fitting feather edge cladding boards?
A minimum overlap of 25mm is recommended between adjacent boards. This ensures adequate weather resistance and gives the finished fence a consistent appearance. On exposed sites, a slightly larger overlap can help reduce wind-driven rain penetration.
Can these boards be used horizontally on a shed or outbuilding?
Yes. Feather edge boards are commonly fitted horizontally in a lapped arrangement on shed walls and timber-framed garden buildings. Fix with the thick edge downward and overlap each course by at least 25mm for effective weather shedding.
Do Tanalised boards need additional treatment before use?
Tanalised boards are pressure treated prior to supply and do not require further preservative treatment before installation. However, all cut ends should be treated with an end-grain preservative, and an exterior wood stain or paint can be applied once the timber has dried fully after delivery.
