The traditional structure of a framework is always composed of the same elements: farm, purlins, rafters, battens, etc. Back here on the battens of a roof: what are they, what are they for and where are they placed?

What are the battens of a roof?

The battens of a roof are baguettes, usually of wood, nailed or screwed horizontally on perpendicular wooden slats called rafters. Together, battens and rafters form the basic structure on which is placed and hung the roof covering. The batten is therefore one of the elements of the roof covering.

The battens are used to hang and support the tiles, slates or any other material used for making the roof. The battens have a length that can be variable. They have what is called a rectangular section of 40 x 40 mm approximately obtained by sawing. The batten is called latte when it is split. The battens are more rarely made of metallic material.

What is the use of the battens of a roof?

The battens, nailed or screwed to the rafters, thus serve to support the roofing of a roof. They support terracotta or concrete tiles, slates, zinc, wooden shingles... or any other material used for making the roof. Whatever this material, it is directly attached to the battens and rafters.

The battens have a supporting role. The whole of this structure of battens is called bedding, lathing or lathing.

Where are the battens of a roof placed?

The battens are perpendicular to the rafters. Battens and rafters together form the upper structure of the farm on which is laid the roof of a roof. The battens are placed at the top of the set of the wooden structure of the roof.

The battens must be arranged at regular spacing, called pureau, but there is no obligation on the width of this spacing, unlike the rafters which must be arranged at regular intervals of 60 cm maximum. The spacing between each batten depends on the roof to be supported, the weight of the loads and the architectural constraints.
