101 Ambi body-gap & Celotex

Mother"

Lee_D uttered summat worrerz funny about:

Oh should add... when you refit if you don't go the velcro route, perhaphs wise in the cab! I slid the new sheets backwards in to the gap above the bulkhead support... then slide them forwards on to the lip above the windscreen, then sideways into the lip at the side... then you only have the edge along the roof reenforcement to secure, smae for the other side and finslly fit the centre bit though I expect if you fit it like mine the cente bit may infact be two bits with a aircon unit in the middle.

Just make sure that the old formica is completely gone from around the edges especially where the screws hold it fast. I bit of cunning with a chisel will soon address this but mind that second skin.

Worrabout this instead ?

I did my cab roof as 2 sections with a join pretty much in the middle (where the strut is). Front one slid in forwards, rear one backwards, then push up and screw in centre..

I dont fancy taking the front one out ever again (it was a fight to get in past the air boxes), but the back one is easy enough if i want to run an cables above it.

the join has a bit of B&Q ally trim with screws through it, and i refitted screws along the front edge. I will probably drill a few in along the back edge too, though its pretty wlel wedged so probably doesnt need them.

Some kind of trim along the sides will probably make it look tidier. If you have a tiny drill you could redrill it and screw upwards. I didnt so chose to screw into the wall and support it. I used plastic trunking (which will hold wires later and doesnt cost me anything!), but some nice ally angle would probably look better

piccy here:

That type of rigid foam is the best insulator but note rigid. It'll flex a bit but 40 or 50mm boards are quite stiff. Expanded polystrene may have more flex in that thickness than Kingspan/Celotex and is still a good insulator. I suspect the expanded poly sold as insulation is the fire retarded version...

There is a web site where you can get "seconds" Celotex/Kingspan for considerably less than your local builders merchant.

Ooh. mine _used_ to look that clean and tidy... ;-)
