Insulation advice

[p.o.w van]

Im after advice on how to insulate me van properly as i intend to use it alot next year,once ive stripped everything out the back this is what im planning on doing.

1. Clean floor,walls to a high stanard.

2.Sort any rust out and paint floor with hammerite.

3.Waxoyl floor and walls.

4.Apply adhesive roof flashing to the walls ( hope this sticks after the waxoyl has been applyed ? )

5.Use space blanket insulation on the walls.

6.Use a vapour barrier over the insulaton on top of the wood battons then refit the 6mm ply.

7.On the ceiling thinking of using celotex ensuring there is a air gap.

8.On the floor some sort of thermal sheeting then refit the 18mm ply.

Can anyone tell me if if this is a good combination to insulate the van and any pros ands cons of using the above materials,many thanks.

sounds good apart from hammerite cos its shi*e!!!!!!!!!!!!!!!!!! try a paint called rustoleum, longer lasting and goes on better, or good old red oxide on places you cant see

I doubt anything would stick to a waxoil covered surface.

That stuff you put under your sleeping bag when camping, (sorry dont know the name) its sound proofing and keeps in the heat (thats why you use it when camping) it also stops moisture. Thats good for the walls, as for the floor thin styrox (the same as what goes under ply wood floors) and then carpet on top. Wood is good to clean but its cold as hell. as for the roof,same as the walls, use neopreane glue. Its the mutts nuts and sticks like s*** to a blanket! you have to warm it before conntact and use in a well ventilated place!!!! tervesia: frisky

you may be right mate but i read somewhere that it would,before i do the whole wall ill try a little square of the flashing on some waxoyl and see what happens.

Nothing sticks to Waxoil......

Nothing sticks to Waxoil......

rust.....

[MinorMatt]

anything light and fibreous does...

ok then its plan B no waxoyl on the sides of the van ill just do the floor after ive painted it.
i aslo read cause of the condesation the van can rust from the inside out i know this would take along time,back to the original question then is the above materials a good combination to insulate me van,cheers.

there ok, but make sure you have good air circulation and the condensation problem won't start.

Reflectix 'Double Bubble' would provide a lightweight, easily applied vapour and thermal barrier which is also far less bulky (more room in van!) than Kingspan.

I did the sides of my van with spray-on underseal, then bubble insulation, followed by rockwool.
Any bits I couldn't get in to were filled with expanding foam

Surely using standard loft insulation is a sure way of speeding up the rust worm??? It will trap moisture, perhaps the space blanket stuff if you seal all the ends with duct tape?

I'm currently going with Thermal foil only - B&Q has it BOGOF at the mo, so works out £10 per roll. Poundland does alluminium tape too

My 2p, based on converting vans in the past....

Use the foil backed bubblewrap over polystyrene sheet. Celotex/Kingspan is great, but far more expensive. (I'm a tight wad)

Using rockwool is a recipe for disaster in many cases.

Use the foil backed stuff as the top layer, and gaffer it to the recess in each panel and you'll get a decent air tight pocket, so no danger of condensation behind the insulation (a bad thing) - the bonus is the reflective properties of the foil backing, keeping heat in and cold out.

Use any sort of sound deadening SPARINGLY (flashing tape seems to be a favourite, although the bitumen tiles are good - and just as good as the 'named' stuff that costs a fortune).

I say sparingly for good reason - have you felt the weight of this stuff?? Covering every panel, as some folk do, is adding massive weight to the van and doing not much. Weight is bad.....

Expanding foam is great - but you need to make sure you'll NEVER need access to those hollows again..... it's kind of a one hit thing.

I'll leave it at that, but if you need any info or help, please drop me a PM

I'm in Scotland and did the roof of my van with that silver bubble airex type stuff.

£10 a roll from B&Q and had left overs!

no more ice inside, no condensation, warm as toast - DO IT!

That's my 2 cents worth anyway.......
