We are using Knauf Eko Roll loft insulation in any parts of panels with moving parts (e.g. the bottom panel of the doors which houses the handle and locking mechanism). This stuff looks super fluffy but it's actually irritating to the skin and not a comfy place for a nap. It's easy to use, just rip apart to size and stuff in the holes... The parts using the Eko Roll are covered are vapour barriered using the same 4mm PET bubble insulation that's under the floor, which is foil taped into place. The reason we've created this vapour barrier is because as there's some chat that the Eko Roll insulation can absorb moisture. (The last van conversion used a similar loft insulation and hasn't encountered any moisture problems, but we want to err on the side of caution!)
Most of the insulation however is using 50mm thick Celotex insulation board which has already all been cut to size (see previous post!)
Next we got to play with some fun skooshy chemicals... The Celotex boards were affixed to the inside panels of the van with Soudall adhesive foam... Which is expensive but very, very, very sticky!
It's applied around the edges of each insulation panel, looking very much like strawberry icing, and allowed five minutes to become 'stringy' and then it's pressed onto the panel of the van.
The adhesive is allowed to dry for half an hour and then we've used Soudal expanding foam around the periphery to further insulate and secure the boards. This stuff is great fun!
We used foil tape to 'control' the expanding foam and keep it where it's meant to be!
This will all be left overnight to dry, and we'll trim any excess expanding foam tomorrow. There's some panels we couldn't complete today as we need to be further along in the build (e.g. have cables finalised)
(The smily faced and ticks is our own little code to indicate which panels are completed in terms of insulation!)
