I don't know about other owners but on a recent winters trip we noticed that the wardrobes got really cold compared to the rest of the storage areas. Has anybody else noticed the problem? I had thought about drilling a couple of holes in the floor so that heat from the garage could rise up into the wardrobe areas, but have decided against it for now. Browsing around a local DIY store I spotted some thin cork tiles and wondered if it would be a good idea to line-out the wardrobes to insulate them. What do others think?
