This tool will calculate the number of Skew Fast warm roof fixings you will require on your project. For pricing and availability, please contact Target's sales team.
Above the rafter only. If your insulation is greater than 150mm, please contact Target's technical department.
If your counterbatten is less than 25mm or greater than 50mm, please contact Target's technical department.
Please see the Tile Weight Guide if you are not sure.
Only between the rafter and the counterbatten (e.g. plyboard). If you are installing through plyboard you may require a pilot hole.
If you have a variable pitch (e.g. mansard roof), you must treat each pitch as a different roof. You can use 90° for a wall.
Don't forget to include both elevations if necessary!
A stop batten runs at the eaves across the full width of the roof, supporting the insulation, and can half the number of fixings required.
Measure the distance between the same point on each rafter (the distance between two rafters, plus the width of one rafter).
This is only used to estimate the Wind Zone below.
Please see the Wind Zone Map if you are not sure.
