Brackets should be installed no more than 600mm apart with end brackets and 100mm from the roof edge.
To calculate the quantity of brackets, simply divide the gutter length ( L) by 0.6 and add one extra bracket (i.e Bracket Quantity = L ÷ 0.6 +1 ).
Therefore, a 15m run of Lindab gutter would require 15 ÷ 0.6 + 1 = 26 brackets.
