So today I got stuck into the Fixing,for the window facings and flashings.I measured the distance between the weatherboards then went to the joinery room with Cam and ripped the timber to 45mm by 45mm.With some of the window headers,I had to use packers so that the face of the H1.2 timber was flush with the window.The facings will be ready to put on tomorrow.Then we can nail up the window top sill flashings.



Fixing for the window flashings and facings.

In class this morning,we went back over sealants and roofing.We were told that for the top of the sheets for the roof that we use vice grips and bend the valley parts of the sheets back,this prevents water from entering the top of the building under the flashing caps.The sheets are to overhang into the gutter by 50mm.The overlap of the iron is 2 valleys.The over lap for the builders paper is 150mm. The top and bottom of the roof has a screw on every rise. and a screw on every 2-3 rise to every purlin.I will set up a string line at each end of the roof,Top and Bottom So that I can line up the sheets of iron nicely and straight.We start off with one full length sheet then carry on.The overlaps of the sheets are determined when we know the main direction that the wind blows for that area,but in our case,We will do whatever as we are building indoors and don't know where the house will finally be placed.
