Insulation Part 2

So the battens were attached with self tapping screws and I coated the back with silicone as it came into contact with the steel

The battens were squared from the floor, as I had used string lines to install it.
I then fitted the 1" polystyrene between the battens, fixing and sealing with silicone.

This resulted in a thickness of 3" below the gunwales and 2" above. Under the gunwales were insulated with strips of polystyrene, again fixed with silicone.


Some areas of the boat were difficult so
I used spray foam from cans to ensure a good seal.
The sides were made longer to create a natural trunking for cables. Where the cable runs were to feed sockets I used 9mm ply channels, so there was no contact between cable and polystyrene, as this could cause corrosion to the outer sheath of the cable.

Skirting channels were also created with ply to house the plumbing.
