popag: INSUL:ATE< INSULATE< INSULATE, to paraphrase a popular TV program!
My deluxe, castillo, bungalow, shed (whatever you want to call it) is insulated everywhere. The roof void has 100mm of polystyrene (most of it re-used, salvaged from the bins/tip from new domestic appliances) FREE.
The inside of the external walls are lined with 50mm "Styro-Dur" (other flavours available) which is 50% more thermally efficient than polystyrene sheet. Stuck to the bare wall with sticky silicone and then that was clad with 13mm plaster board.
The floor was also layered with the Styro-Dur and then covered with ceramic tiles. You can walk on Styro-Dur without it deforming unlike polystyrene.
So, the result is: we use very little wood in the log burner, we tend not to use it until about 6 weeks after others do. The A/C if far more efficient because of minimal heat loss to the outside.
There IS a downside: In the summer, when it's hot outside and you've had the windows and doors open, then it cools downd outside, the heat gets trapped inside the house so you don't get the benefit of the drop in temperature outside.
Before you spend thousands on expensive stuff, do the cheap basics.
Good luck
