Insulation (1 Viewer)

I have a service hatch inside the van for access to the fresh water tank, that I have noticed is a cold spot. On checking there is no insulation on it, so I am looking to put some insulation on the underside of the hatch.

What is the best material to go for and best method of attachment? Would hate to use something that would then need replacing due to water ingress or mould. (Probably looking to cover an area of 60cm x 20cm).

Also what is the best material for lagging external pipes?

Thanks in advance.

closed cell foam sheet for the hatch.

or just plain polystyrene.....its waterproof.

I would get a roll of loft insulation from B&Q and then seal it in polythene bags to make water proof

you will also find space blanket at B&Q which would do the job, its cheap as well

Any particular adhesive recommended, or still not recommended?

polystyrene for the hatch, use PVA adhesive

and domestic water pipe insulation to lag pipes , IIRC .. comes in two internal diameters, 15 and 22mm , it's pre split for easy installation

just had another thought, if you can insulate the tank from the outside rather than stop heating reaching it from the van, the tank might freeze

Good thinking. The tank has a heater, so I do not believe that will be an issue. :thumb:
