Board-and-Batten – Overview
Board-and-batten is a vertical design created using wide cedar boards spaced apart with narrower boards (battens) covering the joins. There are no set board or batten widths - various combinations are used to create different looks suitable for large or small scale applications.
Sizes
While there are no set widths for board and batten fencing, a popular combination is 19 x 89mm battens and 19 x 235mm boards. This can also be reversed with boards installed over battens to create a deep channel effect. The following board widths are available from stock (all 19mm in thickness): 89mm, 140mm, 184mm, 235mm and 286mm.
Grade and Dressing
Western Red Cedar boards are available in kiln dried ‘select tight knot’ grade. Boards are planed on one face and two edges and sawn on one face. Silva recommends installing board-and-batten cladding with the sawn face exposed.
Uses
Aside from board-and-batten fencing, boards are primarily used on buildings for cladding, trim, soffits, fascias and barge boards.
Installation
Board-and-Batten is a vertical pattern created using cedar boards and battens of various widths for a wide range of appearances. For nominal 150mm boards spaced 13mm apart, battens should overlap by a least 13mm. With wider boards, increase batten overlap proportionately.
Boards up to 150mm wide should be fixed with one nail per bearing driven through the center of the board. The overlying batten covering the gap between boards should be attached with one nail per bearing, the shank passing between the edges of the under boards. Use two nails per bearing on boards 200mm and wider placing the nails 65mm to 75mm apart.
