I'm going to be on the road in my van (1984 Devon Moonraker) pretty much all this year - mostly at camp sites - and wondered whether it would be worth investing in some window insulation screens? By how many degrees would you say they help keep in the warmth? (Oooh, I can't word that sentence correctly, but you get my point!)
I've got my electric fan heater which brings the temp up to a good level but wondered whether when I switch the heater off, I'm going be losing all the heat - and wasting money - unless I invest in some insulation like this.
What d'ya think? It's a shame, just saw some of these sold on the 'For Sale' section - damn it!
Thanks for any advice as always,
PA
