We want to spend more time in higher latitudes and the plan, before Covid and Brexit got in the way, was to head up to Svarlbard in Spring 2021. So after sailing back from the Azores, we put Shadowfax into Plymouth for the winter and began the job of improving the insulation, particularly in the main saloon.
The main living area of the boat is pretty large and the coach roof extends up on all sides, making it more prone to loosing heat.
Fortunately the roof cavity is fairly large and we remove 25 mm of polystyrene that was already up there and replaced it with a combination of Armaflex closed cell phone and SuperQuilt foil insulation.
Here’s a video explaining all!
