Hi all
I am building an extension and the width of my extension is 6.5m (the width of my house). The length will be 6m. The joists will be going width ways (6.5m long).
My plans state I must have a drop which is at least 1 in 80. So, by my calculation I need a drop of 75mm (1/80*6*1000)
I have been led to believe that it is better to get a piece of wood which is lets say 100mm high at one end so the other end will be 25mm. This way it is easier to nail into the joists.
What I'd like to know is the following...........
1) Does each furring have to be 6 meters long? (I'm assuming it does)
2) Should I make sure that if the drop needs to be 75mm then I should have one end being 100mm and the other end 25mm?
3) What wood should I use?
4) I'm assuming a good quality nail gun will be the best way of holding the furrings in place.
All answers are very much appreciated.
