Practical External Cladding

This morning, as a group, finished off the take off excersise number 6. As i was already half way through it didn't take long. After this we moved on to making a height stick, used to represent the layers of cladding going up the wall. On one side we marked out lines for 185mm cedar cladding that gave us 160mm coverage with a 25mm overlap, which as Mike found out was the standard coverage overlap. On the other side we worked out how many panels of pine cladding would be required and the equation i used to figure it out was as below:
152mm total panel width
152 - 25 (overlap coverage) = 127
2520 (height of the wall to be covered) / 127 = 19.84
Round up to 20 panels to cover the wall.
2520 / 20 = 126
so 126 coverage with each board with a (152 - 126) = 26mm overlap.
After this we moved onto actually putting on the cladding. Behind the cedar and pine cladding we placed on a water proof lining that is coloured blue to stop reflection of light, and also acts as an insulater. On a framed timber wall it must perferated so that the walls can breathe, stopping moisture build up due to condensation.
Mike and Greg worked on the pine cladding over the plastic lining, Dan and Rhys worked on the cedar cladding whilst Greg and I worked on lining the back wall with sheets of hardiflex.
This required us to put in trimmers behind where the sheets were going to join as per AS1684 guidelines. Cutting and installing the sheets was relatively easy and fixed them with clout nails. We first of all got the overall span between the two corner pieces of timber, halved it and marked a line. We then placed the tape length of 600mm on the mark and then marked 1200mm and 0mm, for the width of the middle sheet. That way we would have even sized sheets either side of the full sheet, which worked out to 1000mm.
Around the corner of the house we applied 3 sheets with vertical joins in them. First of all we put on a sheet on the bottom and fully nailed it. We marked 20mm from the top of the sheet down, and we then put on the Alcoil over the top of the sheet, with the bottom of the Alcoil lining up with our 20mm line that we marked. We pulled it tight and nailed it down with clouts.
After this we put on the next sheet above it, pressing it down to the top of the bottom sheet, which made the Alcoil bend outwards. Once this was done we nailed in the top sheet. After the Alcoil had been placed in we are going to placed a batten over the top of the join.
