Roof Insulation & Cladding

I was going to fit traditional sisalation paper however after some research it became apparent that blue and silver sisalation is old technology and has been replaced with bubble wrap like insulation. 

A roll of "Air Cell" insulation and aluminum tape were purchased off ebay. The plan is to also use it on the walls.

The insulation was cut to length on the ground and secured with shade cloth "nails".

Underside of the Air Cell

Air Cell insulation was overlapped and the join covered with aluminum tape. Note that the Air Cell overhangs the lower roofing batten so that condensation can drip off without wetting ie rotting, the batten. 

As I am constructing the tiny house without assistance, I have had to develop ways to compensate for lack of hands. In the case of fitting the sheets of roofing iron, blocks were temporarily nailed bottom roofing batten to stop them sliding down while securing them.

The first sheet of roofing fitted.

Gables

Batten screws being fitted to battens.

The barge board will be secured via the battens and in order to stop flex, blocks of wood are cut to butt against the last rafter and back of the barge board. The picture below shows the barge board prior to fitting. Note that the end rafter has been infilled with framing and the rectangular framing will be were the loft window will be installed.

The angle of the cut for the top of the barge board should be the same as the angle that the rafter was cut. Im my case 45 degrees.

Barge board fitted and held in place with batten screws.

Color Bond Commercial Building

Was driving past a color bond commercial building so stopped into see how the corners were handled.

Roof Battens

The roof battens were placed over length and 3 per side. They were positioned straight by using a string line and held in place by nails. 

View of the fitted battens from above.

Note that batten screws were subsequently using to secured via batten screws.

Batten screws will tend to split wood if the wood is not pre-drilled and they are also hard on drills due to the torque required to screw them.

Batten is held in place at the ridge board via skew nailing and hoop iron and clout nails.

The battens have been trimmed in preparation for the fitting of the gable ends.
