GRP narrowboat

[Lottie]

We are refitting the above and would like to know the best way to fit plywood to the grp insides. Can we fit straight to the grp or should we fix to batons? Any help gratefully received.

You want to fit to batons to give it a cavity and get some insulation in them cavitys.

Never done one, but that sounds about right to me. Celotex insulation or similar?

Yes when I did mine I used kingspan.

Absolutely, battens with insulation then board over the top. Avoid polystyrene at all costs, this has been used in the past but has proven to store up trouble, issues with the PVC insulation on wiring being affected and is more of a fire hazard than other insulation materials.
