I'm looking to strip out the contents of my van ready for its new interior. To fit the interior They need to have doors, floors and walls in ply plus also a roof lining. For the roof I was thinking of some thin ply so I can fit recessed lights and either cover with a material of wife's choice or just lightly varnish. Either way I think it needs to be finished before interior units go in. I suspect it would be difficult to change this after. Not like changing door cards. Is this type of roof lining difficult to do? Are there better alternatives, bearing in mind I want recessed led lights? As always your help is appreciated.
If you can get yourself a template or buy it precut, I'd say its the easiest option. I've seen them installed by means of some J shaped trim on either side which the board sits in or screwed directly to the metal work. It will have to be 2 or 3 parts, and if you go with ply make sure it is thin enough or heated as it can split when bent.
