Board and batten, planche et baguette, planche et couvre-joint
Board and batten is vertical siding: wide boards standing upright, with a narrow batten covering each seam. That is where the name comes from.
Shopping for it in Quebec is harder than it should be, because nobody writes it the same way. Home Depot calls it planche et baguette, BMR calls it planche et couvre-joint, CanExel keeps the English Board & Batten, and some listings never name the profile at all. The same wall can cost you double depending on which listing you happen to find, simply because you never found the other three.
- Board, or planche: the wide part, installed vertically.
- Batten, or baguette, or couvre-joint: the narrow strip covering the seam.
- In vinyl, both are moulded into the same panel.
- In fibre cement and engineered wood, they are two separate purchases.
