A Batten is a strip of solid timber, rectangular in cross section, used in roof construction to provide the fixing point for roof tiles. With full roof boarding, counter-battens are sometimes used, installed at a right angle to battens.

A counter-batten is a strip of square timber which is nailed onto a rafter to provide some distance between a breather membrane and a batten. Counter-battens allow the water penetrating under the tiles to flow down the breather membrane without any obstacles, such as battens fixed directly to rafters. It also provides the necessary ventilation space for the roof covering.

Counter-battens | 24 | 48 | 6 |
