Well the liner was well and truly tested over the weekend up at Wasdale Head up in the Lakes.
We didn't put the external topper on as the idea was to test the new internal liner and see how it performed.
As usual in the Lakes in mid February the weather wasn't good. Friday night we had a mixture of rain, sleet and snow, very heavy at times. Saturday night it pretty much rained all night and the wind also got up blowing the rain sideways into the roof.
Pleased to say the inside of the roof stayed bone dry all weekend with the liner in. On Sunday morning I opened one of the side "windows" in the liner and felt the inside of the roof canvas. This was fairly damp and I'm sure that without the liner the mattress would also have got wet where it touched the roof canvas sides.
We normally sleep upstairs but as it was around freezing we decided to stay downstairs but left the bed platform raised to see what effect the liner had on retaining heat. I wasn't really expecting it to do much as after all it's not designed to be a thermal barrier. However it really made a difference as it virtually cuts out any drafts. A bit of air still comes in round the top of the liner as it's impossible to seal it completely around the top so we still had some ventilation. Normally in these conditions we would definitely have had the bed board down and the slats closed up.
The internal light grey colour makes the inside of the van considerably lighter as well and matches in well with grey Cali plastic trim.
The liner is fastened in with Velcro, top and bottom, so there is no need for any alteration at all to the Cali, about three quarters of an hours job to put all the top connectors in, hang the liner up and fasten the sticky back Velcro to the ledge round the bottom. This means it could be moved from van to van if necessary.
All in all it does what it's designed to do excellently and folds up in the roof without any problems.
General inside view
Upstairs with the bed board down. The liner is fastened at the top rear with Plasticard sewn to the liner and pushed between the roof liner panel and the actual roof.
Side "window"
The front hangers in position. These are Plasticard again pushed between the roof liner panel and the roof again like the rear. Velcro is stitched to the card which then connects the liner.
A hanger detail
A series of Vecro hangers support the liner down the sides. These again are made from Plasticard which simply slots down into the roof fabric channels.
Use is also made of the existing roof eyelets. Elastic stitched to the liner is threaded through the rear one, then the front and connected back to the rear one with a hook. Turning he rear eyelet round pulls the liner closer in to the side.
Bottom detail at the sides where the liner is notched out to clear the struts. This also shows how the liner is attached at the bottom with the sticky backed Velcro.
I would say that the bungy for pulling the fabric in when the roof is closed is essential to ensure that the canvas and the liner are pulled in safely when the roof is closed. Without this I could see that the liner may bunch up in places and possibly push the canvas outwards trapping it in the pantograph supports.
I hope this gives a reasonably clear indication of how the liner looks and works.
I'm sure Nick at Comfortz will be able to help out with any queries that may arise.
