Ordering Flashings Information
Flashing drawings
Standard Flashing Drawings
All standard flashing drawings are shown as non-tapered, however can be ordered as tapered flashings using the “Ordering Tapered Flashings” details outlined below. Letters describe the dimensions of each plane of the flashing, and numbers describe the angle. You will need to advise us of all dimensions, and identify any angle which is not 90 degrees.
Order Methods
Clock Method For Phone Orders
Commence at the centre of the clock. Draw a straight line from the centre to the number on the clock (1-12 ) at the required angle, representing the first line of your flashing drawing. Where the pen stops becomes the centre of the clock for the next line. Complete the flashing using this method. For tapered flashings quote near edges first. Repeat for back (use same letters) unless otherwise indicated.
Page Method
The page method describes the flashing as it is drawn on a page. Commence drawing the flashing at the centre of the page describing the direction of the line as you draw it, advising if the line moves vertically up or down the page, horizontally left or right, or to which corner of the page. Also advise the length of the line. Do this for every line in the flashing, advising of any included angles.
