The morning was spent trimming all 22 iBeams to exact lengths! We got out our chop saw on the bench and along with two extension benches proceeded to very carefully get the angle of the cut just right, at 1.3degrees which is the slope of the roof! Once the saw was set up and tested with samples, we carried each beam to the saw for one end and then spin it around to cut the other end! Well it wasn’t that easy, walking the whole iBeam out of the garage, turning it around and then walking it back in again! And remember each beam is 9metres (29feet) long!! We walked miles today!

We also glued and stapled strips of fluffy geo-textile over the holes drilled yesterday in the first i-beam to act as a filter for the incoming air.
