Winter Warmer: One of the big changes to the chalet will actually go probably almost entirely unnoticed by renters. Darren and I (and indeed any of our previous fffffreezing guests over the past season) will most certainly notice, given how baltic our first experiences in the chalet were all those months ago. When we first arrived, in minus 12 or so temperatures and much constant unending falling snow, we had to keep on all our outside clothing inside the chalet too. A big part of that lack of temperature distinction between inside and outside, was because the building had lain empty for so damn long and it just takes a good darn while to take that terrible freezing edge off the floors and the walls. That and the lack of any central heating (hello tiny blow heaters), and also the small amount of power supplied to the chalet, so we couldn't even max out on tiny heaters scattered around everywhere either. Having said that, when the building was stripped right back, having only a few tiny centimetres of anything resembling insulation really didn't help all matters. And all in a wooden building.
A Brave New Warm World: So new sparkling chalet will look super dooper, shiny and new, but will crucially be super warm too. And because we're recladding the outside, the heat won't be leaking out through all the enormous holes, as it currently does. In real terms, we're actually increasing the width (? depth?) of the insulation from around 7-10cm to over 20cm, and adding in some windproofing to boot, all in all will make a tremendous difference to the efficiency of the building, but also ensuring that it'll be far easier to keep snug and warm inside. And on the flip side, during summer, the building won't overheat either.
