Motorhome insulation (1 Viewer)

[swampsnake]

Just wondering how well modern 40k-50k motorhomes are insulated?
When I was considering a panel van conversion, the insulation was probably the single most important issue. I assumed that was because of the steel skin. Most were insulated with 50mm Celotex. Are motorhomes fitted with similar?
The motorhome body is GRP, is this correct? Is that better than steel from an insulation point of view?
Also, are the windows generally double glazed?
Finally, where do the full timers go in winter? abroad?
I'm so sorry for all the questions and if it's all been said before but i'm brand new here and this forum is HUGE!!!, gonna take months to read everything!

The issue with PVCs isn't thickness of insulation. In fact, this is usually quite good (i.e. 50mm). However, compared to coachbuilt models, there is way more cold bridging, because they use steel spars, rather than having sandwich construction with few interloping structural elements.

At 40-50k I wouldn't be buying a new one. If You want proper insulation, fully winterised, double floor, inboard tanks double glazed egc, you're going to need to look at 5-10 year old usually German.

Winter destinations tend to be skiing or Spain or Morroco.

Also, with a PVC and large sliding door......there is a big gap for warm air to rush out when opened!

If it's a coach built or an A class or in other words anything other than a PVC then the body will be GRP or aluminium or quite possibly a bit of both, yes windows will be double glazed plastic. The wall panels may or may not be fully bonded and the thickness of these panels varies from van to van so you need to do your research, and then you need to look into where the tanks for water and waste are housed and are these well insulated.

Lower cost and nearly all Brit built vans use polystyrene for insulation, higher quality vans used a closed cell foam like PU which gives far better insulation also they take far more care avoidinding cold bridges.

Thanks, I've just noticed the section listing foreign manufacturers so I will more research!

I'm a full timer, unfortunately I still have to work but my work usually comes in blocks of weeks, in the summer I might work 8 weeks then have 4 weeks off to go mooching. In the winter I hunker down in a mates yard with ehu and water on my pitch, facilities are available because attached to his yard he's got a cs.

Some of us might open the door only part way
