Renovation Revalation

 
The plan had been to spend four days cladding the upper part of the exterior with ship lap and putting up plaster board on the interior walls. Funny how the best laid plans don't always work out.

On investigating the state of the building frame, what had seemed like a little bit of wet rot turned out to be worse than expected with some timbers rotted right through.

The rot appears to be due to two causes, leaks in the guttering and cedar shingles that had been nailed directly onto the original ship lap cladding which trapped water between the two.


So instead of the original plan, I spent my time (with the help of a friend, Andrew) cutting out the offending timber and splicing in new. First the external shingles and cladding was removed, then the roof was propped up and the rotten timber cut out. Once cut and cleaned up, new kiln dried timber was treated and spliced into the remaining timber frame.

In place of the ship lap cladding, OSB board was attached to act as a sheathing, this also acted to add extra stability to the structure. Once complete, the props were removed and the walls remained standing :-)
The final part of the wall building process that was completed on this trip was to put up house wrap to keep out the rain.

The final wall layers will be: (from outside to inside)

  • Thermowood ship lap
  • Battens
  • Exterior building wrap
  • OSB sheathing
  • Wood frame insulated with thermofleece
  • Inner vapor barrier membrane
  • Plaster board.
