Rafters

mm -- the distance between the middle of each rafter.

Buildup of Materials over Rafter

Skew Fast are fixed through the counterbatten and into the rafters through all the materials between these two.

Tile Batten
In rare cases you can fix through the tile batten, but this often means adjusting the tile batten spacing so it is cumbersome. Once the counterbattens are fixed down, tile battens can be fixed down to the counterbattens in the usual manner. If you wish to fix Skew Fast through the tile batten, please call the Target technical department.

mm -- Above the rafter only

mm

kg/m²

mm -- Between Rafter and Counterbatten (e.g. Ply)

Roof Details
