I have experience and great interest in timber construction, so I was pretty pleased to get a job with Swissline Designs where I will work under Swiss Master Carpenters. I had a great first week working on a house in Vredehoek. A very old single story house has been gutted, and a second story / roof living space is being added. The original brick walls of the ground floor have been kept and a new suspended timber floor added. The 2nd storey, which may officially be called a roof-space, consists of exposed timber rafters supported by a large laminated timber ridge beam on timber posts. Set back from the ground floor walls, are dormers running the length of the building on both sides, allowing light and views. (photos coming soon...maybe drawings if i have the time)
I spent the whole week balancing on battens and purlins on the rooftop. It was tall, steep, and hot as heck, but sure beats sitting in an office. We installed a membrane called Alububble which acts as an insulator, a reflector of radiant heat, and a moisture barrier. We secured the Alububble using 38x38 treated pine battens nailed directly to the top edge of each rafter. Not crossing the rafters like purlins or ceiling battens, but along the tops of each rafter. The purlins were then nailed to these (right through to the rafters) in the usual horizontal manner. I was told that the architect wanted the 38mm battens to increase the space between the roof tiles and the membrane for greater air flow.

I started writing this post on Saturday and got sidetracked and thought I could finish it on Monday. Its Monday now and was hotter than hell on site and I'm completely exhausted so although I had some other stuff to add, this is the end of this post.
