Iridak Long Tile (ILT)

ILT is a modification of the Clay tile roof. Observations of the Clay tiled

roofs showed that it imposed its weight in addition to other imposed loads

directly onto its structural carcassing which tend to fail when there is a slight defect in the carcassing

material. Another aspect is the discolouration of the clay tiles which gives an unpleasant look over

time. This gave birth to the Long tile which uses the Zincalume sheets in the formation of the design

with the tile appearance. It has the advantage of being lightweight and has wider coverage than the clay

tiles which makes it economical in terms of cost. The only disadvantage is that the structural carcassing

has to have close purlin members to make the sheet sit well. It has an effective coverage area of

900mm and a depth of 28mm making it difficult to distinguish between the long tile and the clay tile

from a distance.
