I have a 28x10 static which we live in now. As we are going to be there in the winters, I would like advice on how best to add insulation.
1. to externally use boards or rolls of insulation materials, with battens and then waterproof with ? [cladding] - both walls and roof.
2. strip existing insulation and replace with something better [what] and replace panels. how tricky is this?
3. line walls internally - though dont want to decrease internal space too much
We have a gas fire, can replace with a burner though.
I have added thermal liners to curtains.
I have carpets and extra mats/rugs on the floor.
I will be putting a 'skirt' between the base and the ground.
I will consider putting in some/all double glazing if its worthwhile.
Any advice is worth it, incuding possible pricing estimate and ease of the work involved.

use the insulation you mentioned. put pvc skirting around bottom and, this is tricky but easily done use the expandig foam you mentioned to insulate the walls. not sure if you should block up vents though, even if you dont use gas fire. Also foam is a1 fire rated. and no, it wont push the walls out

i'm really struggling with this one but so far we have rock wooled the entire underneath (this is really cheap at the mo in B & Q £3.00 for three rolls we used £12.00 worth on same size van to cover all plus some left over) really easy to do because underneath is split into sections then we just stapled wool to boards. filled any empty spaces in side with insulation ie, underseat storage. We are looking at cladding inside with 25-40mm celotex or polystyrene sheets. We don't use a gas fire so we were able to fill alot of the ventilation gaps with expanding foam. Also we are investigating double layer honeycomb perspex with has good insulating properties to cover the windows in the winter. apart from that we are stumped.
